I need a small repo / script that turns the whole OpenClaw + Telegram + LLM stack into a single-command experience. When a user supplies nothing more than their Telegram bot token (and an OpenRouter key for Deepseek), the script should: 1. Pull the latest stable release of OpenClaw. 2. Build and run it inside a Docker container. 3. Spin the container up on Railway via their CLI/API, setting all required environment variables automatically. 4. Wire the bot to speak English only and route every prompt through Deepseek served by openrouter. I am expecting: • A clean Dockerfile (or docker-compose) and a Railway template that work out of the box. • A (or similar) that asks for the two keys and does everything else unattended. • Brief inline docs/readme so any n...
Project Title (Freelancer.com) Build a Web Version of My Telegram Channel on My Domain (Migration + Admin Posting) Project Description I run a Telegram channel for Solana trending updates and I want to migrate this content experience to my own domain website. The goal is to have a clean, fast website that shows the same type of posts we publish on Telegram, but fully owned by us on our domain, with a simple admin system so we can publish posts easily. This is not just a landing page. I need a real web platform that can display posts in a feed style, support categories/tags, and be optimized for mobile users. Core Requirements The website must have a public feed page that displays posts similar to a Telegram channel timeline. Each post should support text, images, and links, and optional...
I need a fully-coded Relative Strength Index indicator that plugs straight into Quantower via its open API. The core requirement is simple: the look-back period must be user-adjustable from the platform’s settings panel so I (or any trader) can fine-tune it on the chart without opening the source. Please keep the script lightweight, coded in C# as recommended by Quantower, and use the platform’s standard drawing and event hooks so it behaves exactly like a native study—automatic repaint on bar close, proper scaling on sub-panes, and settings persistence between sessions. I am only targeting this one technical indicator right now, but if you design the class structure cleanly, adding overbought/oversold bands or divergence logic later should be straightforward; solid...
I’m building a full-stack, fully secure money-exchange platform that spans Android, iOS, and a responsive website. The public landing screen must fetch and display up-to-the-second buy/sell rates even for guests, then invite them to sign in. Authentication will rely on Google Authenticator one-time codes; every sensitive endpoint must be locked behind this 2-factor flow. Once inside, customers need a clean dashboard where they can: • place buy orders • place sell orders • review a complete, filterable transaction history Behind the scenes I’ll need an admin console that lets me adjust spreads manually or, at the flip of a switch, pull live forex data from an API (feel free to recommend the most cost-effective feed). All price changes should propagate ...

I need a propensity-modelling software package that plugs directly into our CRM system, website analytics, and sales database, unifying those streams into a clean, continuously updated dataset. On top of that data layer, the build must train, evaluate, and deploy the best-performing predictive models—whether regression, decision-tree, neural-network, or any other technique that proves superior—then surface the results through a lightweight web interface and an API our teams can call in real time. Key deliverables • Automated ETL jobs and data-quality checks for the three sources mentioned above • Modular training pipeline with experiment tracking, lift/ROC reporting, and feature-importance visuals • Scoring service exposed via REST (or GraphQL) endpoints plu...
We are looking for an experienced Windows developer to research and implement a solution related to low-level input handling and Windows system behavior. The project involves investigating how Windows processes certain input events, identifying limitations, and building a reliable technical solution. This is a system-level engineering task and not a UI-focused project. Work will be completed in two phases. The first phase focuses on research, reproduction of the issue, and a working proof of concept. The second phase focuses on refining the implementation and delivering clean, production-ready code. Skills Required: C++, Windows App Development, Desktop Application, Standalone Application, API
I need a small middleware service that can pull live inventory levels from a third-party POS platform (it’s not Shopify, Square, or Lightspeed—so please be comfortable discovering or reverse-engineering a different API or database schema). The single purpose is to keep my own server in sync with whatever is on the POS in real time. Here’s what the job looks like from my side: • Goal Every sale or stock adjustment in the store should trigger, or at least very quickly reflect, a quantity update on my server so the numbers stay accurate across all of my channels. • Flow I’m picturing 1. Authenticate to the POS (REST, GraphQL, WebSocket, direct DB—whatever the platform offers). 2. Detect inventory changes continuously—ideally through a web...

I’m building a crypto-centric trading app and need a partner who can handle the technical core and the growth engine in one streamlined engagement. On the product side, the app must stream real-time market data from leading exchanges and display it flawlessly on both mobile and web. Low-latency price feeds, order-book depth, and responsive charts are essential so users always act on up-to-the-second information. On the marketing side, the goal is to drive a steady wave of qualified traffic to the app’s landing pages. My focus is on backlink building paired with content marketing; together they should strengthen domain authority and keep fresh, insightful crypto articles ranking for targeted topics. Keyword optimisation is optional—I’m prioritising high-quality l...
I want to build an end-to-end platform that lets any business spin up its own virtual sales assistant, train it on brand-specific data, and deploy it in minutes to a website, a mobile app, or an eCommerce storefront such as Shopify. The assistant must converse naturally, answer customer questions, recommend the right products or services, and qualify leads before handing them off to a human team or a CRM. The project covers everything from the AI core to the customer-facing widgets. I need a secure multi-tenant backend where companies can upload FAQs, product feeds, and sales scripts, then fine-tune a large-language-model–based agent around that content. A no-code dashboard should expose conversation flows, tone controls, and performance analytics. On the delivery side, I expect lig...

I’m ready to turn my idea into a fully-functional Android application and need a developer who can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus. Please let me know: ...

I need an experienced Angular developer to jump on AnyDesk with me and get a fresh project up and running on my machine. This is a single-session engagement: once the app builds, serves, and I can rerun it on my own, we’re done. During the session you’ll initialise the workspace, install and configure the necessary dependencies, lay out a clean folder structure that follows current best practices, and verify everything compiles without errors. If there’s a smarter way to organise modules, services, or shared assets, I’m happy to follow your lead. You must be comfortable driving the setup while explaining what you’re doing so I can maintain the project afterwards. Clear spoken English, a stable connection, and availability to start immediately are essential. ...
The prototype was implemented cross-platform using React Native and Firebase as a backend. Fundamental implementation choices prioritized security and interoperability: Security: AES-256 encryption of data at rest; TLS for data in transit; role-based access by family members versus clinicians. Interoperability: A modular API with FHIR-compatible endpoints for eventual EHR/RPM integration. Offline capability: local caching and deferred sync to accommodate intermittent connectivity. Accessibility: large font toggle, voice prompts, and simple language; eventual localization into Swahili and French for pilot implementations in East Africa and West Africa. Care dashboard (daily/weekly view): Task list with confirmations and shared task assignment among multiple family caregivers. Tasks can be r...

I already have a working desktop budget-management application and now I’m ready to extend its capabilities. My priority is to add new features rather than fix bugs or work on performance tuning, so I need someone who enjoys feature development and can plug into an existing codebase quickly. The current build is stable and fully documented; you will receive the repository and a brief walkthrough of its architecture at the start of the engagement. From there, we’ll outline the features in detail together—think smarter reporting views, additional expense categories, maybe a quick-export to CSV/PDF—then agree on a milestone plan so you can deliver iterative updates and I can test on my side. Deliverables (per milestone) • Updated source with the agreed fea...
I need someone to help me setup a system to manage accounts. I do have a gps tracking system where we charge clients monthly a fee to use the system. Some clients have multiple login account, these need to be grouped together so when a client dont pay we dont close 1 and miss to close the others and he will keep tracking on other account. We receive cash payments, swipe and bank transfer. We use freshbooks to process payments and based on open invoices we close accounts on my server website. I need someone to help me with creating a system to manage things and maybe help me keep in track of new clients and existing clients. Maybe create something or a website or somehow a way to keep informations accurate
I’m ready to launch a proprietary AI-driven builder inspired by Lovable and Base44. The vision is a web-based platform where non-technical users can assemble complex assets in minutes while the system quietly orchestrates the heavy lifting—model selection, training, and deployment—behind the scenes. You’ll guide the entire build: architect the cloud infrastructure, code the core engine, design an intuitive front-end, and wire everything together with robust APIs. Think drag-and-drop creation, reusable templates, realtime previews, and seamless connections to popular third-party tools so that users can publish or integrate their results without touching code. On the AI side I’m open to the mix you feel best suits the goal—classical machine-learning pip...
I maintain a live Angular + Dotnet Core application and need someone who can sit with me in Bangalore—preferably on-site, at least for the first few sessions—to quickly enhance the backend. The core goal is to improve an existing system, not start from scratch. Right now the Dotnet Core layer is showing its cracks: data isn’t syncing cleanly between services and several API calls are failing on production, causing intermittent errors in the Angular front-end. I’d like you to dive straight into the repository, isolate the synchronization logic, patch the API communication issues, and leave the codebase cleaner and easier to extend. Key deliverables • Stable, fully functioning Dotnet Core backend with no data synchronization lapses • API endpoints retu...
I’m looking to add a small but essential feature to my PrestaShop 8 store: the option to flag one or more specific products so they always ship for free. Here’s what I need: • A fully installable, PrestaShop 8-compatible module that lets me select individual products in the back-office and mark them as “Free Shipping.” • At checkout the module must automatically set the shipping cost of those marked items to €0, without affecting normal rates for everything else. • The change should work seamlessly with all native carriers, taxes, and combinations, and display the “Free Shipping” notice in the cart and order summary. • Clean, override-free code that follows PrestaShop best practices, plus an uninstall option that remove...
This is a Technology-sector project centred on software development, specifically a web-based application that will evolve over time. The goal is to ship an initial MVP and then move into an iterative release cycle, adding new features, refining UX, and keeping the codebase healthy with regular refactors and testing. The work will be continuous rather than one-off, so clean, well-documented code and reliable communication are critical. Git version control, REST/JSON APIs, automated tests, and modern front-end frameworks all fit naturally into the workflow; if you already have a preferred stack, feel free to mention it when you reply. Deliverables at each milestone should include: • All source code committed to a shared repository • Brief release notes summarising changes and ...

I need a seasoned backend developer to design and implement a secure REST API that lets my users check award-seat availability (Avios) directly from Iberia.com. The core of the job is to automate the full search flow — login, query, filter, and return the results — while keeping the service fast and reliable. Authentication & security The service must issue and validate JWT tokens for every request beyond the public health-check route. Token refresh, revocation, and a simple role model (“user” vs. “admin”) should be built in from the start. Flight data extraction I do not have official Iberia developer access, so we will need to pull the data ourselves. I’m open to whichever tooling you are most comfortable with — BeautifulSoup, Sel...
I need a robust NinjaTrader 8 add-on that stops traders (my coaching clients) from sabotaging their own plans. The core functions are clear: • Block the entire NinjaTrader platform for the rest of the trading session once predefined thresholds are hit. • Allow me to set hard limits on daily PnL, total number of trades, or consecutive wins/losses—mirroring typical prop-firm rules. • Offer a straightforward graphical user interface inside NinjaTrader so coaches and traders can adjust these rules without touching code. When any rule is breached, the add-on must automatically disable order placement and chart trading for the remainder of the session—no manual override. Additional requirements • Licensing: link each installation to the machine ID (or a...

I want to enrich my online shoe store with an AI-powered recommendation engine that studies each shopper’s purchase history and instantly serves up the pairs they are most likely to buy next. The model can draw on three data streams—user account data, my e-commerce platform records, and any third-party customer datasets I supply—to build a unified profile and surface truly personal suggestions. Here is what the finished job looks like from my side: • A trained model (Python preferred, TensorFlow or PyTorch are both fine) that ingests the above data sources, updates itself regularly, and outputs ranked product recommendations in real time. • An API or embeddable snippet I can drop into the product and home pages to display “You might also like” sh...
I am developing an end-to-end platform that pulls live claim-related data from Revit models, runs it through a FIDIC rules engine, and then immutably stores and certifies every step on Hyperledger Fabric. The objective is clear: the moment a potential claim is flagged in the BIM environment, it should be automatically registered, classified, validated against the relevant FIDIC clauses, and published to an auditable ledger—with a web dashboard showing the entire trail in real time. Scope of work • BIM connector: a service that extracts the necessary objects, properties, and metadata directly from Revit (IFC compatibility is a plus) and hands them to the API. • Integration backend (API): a lightweight, well-documented REST/GraphQL layer focused on automated workflows&md...
I need a small script or micro-service that calls an odds API once per day and extracts NBA player-prop markets—specifically all categories—for every nba game on the board. The job is only about player props; spreads, moneylines, and totals can be ignored. Here is what I expect: • Code (Python or Node preferred, but I’m flexible) that hits a public or paid odds endpoint, parses the daily response, and saves the three prop categories in a tidy JSON or CSV file. Excel preferably • A clear spot in the code where I can drop my own API key and set the run time (cron, Cloud Function, Lambda, etc.). • Basic logging so I can confirm the call succeeded and see any errors. • Quick README explaining setup and the output format. If the script runs co...
I need an end-to-end AI assistant that first and foremost sweeps through years of email, automatically deciding what can be deleted, archived, or highlighted so my storage stops ballooning and my focus shifts back to real work. This inbox-cleanup engine is the absolute priority, so your proposal should open with how you will train, test, and safely deploy that module for major providers such as Gmail and Outlook. Once the email layer is solid, the same system must branch into the routine drudgery that clogs a workday: filling out repeat documentation, kicking off standard operating procedures, and nudging me when something has slipped. Think of it as an AI Ops Assistant—handling docs, reminders, and other predictable workflows without supervision. A built-in calendar is next on the...

I need a clean, modern-looking e-commerce site that showcases my physical products and lets customers add products to their cart and at checkout page customer must be able to fill their information to place the order, once order is placed a GST quotation must be sent to customer from whatsapp. As soon as they hit “Request Quote”, the site should automatically generate a PDF quotation or pro-forma invoice and push it to the customer through my mobile number (SMS, WhatsApp, or a similar gateway you recommend). Because I already handle stock control and invoicing elsewhere, the site itself doesn’t need a full inventory or billing module, but it must stay in sync with my existing billing software. A two-way API connection that pulls product data and pushes confirmed orders...
I’m working with the AI-Powered Physiotherapy Recovery Flutter template from CodeCanyon (see link above) and now need a purpose-built backend to handle its scheduling flow. The mobile side is ready; what I’m missing is the server logic that lets therapists create, update, and cancel treatment sessions while automatically sending SMS reminders to patients ahead of each appointment. My priorities are clear: – Robust session scheduling and management endpoints that the existing Flutter code can call seamlessly (REST or GraphQL, your choice as long as it’s well-documented). – A background job or queue that fires SMS reminders at configurable intervals—Twilio, Nexmo, or another SMS gateway works for me provided it’s abstracted cleanly so I can swap p...
I’m putting together a proof-of-concept and need a single-page web app, built in React, that mimics the look and feel of Dexscreener but runs entirely on simulated data. Candlestick charts must be rendered with , while the surrounding stats—price, 24 h change, market cap, volume, etc.—update in real time. Flow I envision • A Telegram bot (already under my control) sends JSON payloads with the latest price, market cap and any extra metrics I decide to test. • A lightweight server receives those webhook calls and streams the data to the front-end (WebSocket or SSE—whichever you find cleaner). • The React UI redraws the active candle and refreshes all displayed figures instantly, giving the impression of a live market feed. Key requirements &...
I want the running total revenue from my Shopify store to show on a Wi-Fi-enabled physical counter that sits on my desk. The job is to build the small bridge between Shopify’s JSON API and the hardware. Here’s what I already have and what I need from you: • Data source – Shopify: I only care about the store’s Total revenue figure. A lightweight call to the REST Admin API (or GraphQL if you prefer) is enough. I will supply the private-app credentials. • Destination – Hardware counter: It connects over Wi-Fi. You can target it with plain HTTP, WebSocket, or MQTT; whichever is simplest to flash onto a common ESP8266/ESP32 controller. I can handle the flashing if you give me the compiled binary or the Arduino/PlatformIO project. • Service layer:...
I want a single code-base app (React Native or Flutter is fine if it meets Apple and Google policies) that lets my users save any public video or audio they encounter online—Instagram Reels, YouTube clips, Facebook posts and beyond—directly to their device. The app must automatically detect the highest available quality, then offer MP4 for video and MP3 for audio before placing the file in a tidy, built-in library. The admin could see each user link they downloaded in a admin dashboard where he could see all people whom they are using the app. Core flow • Paste or share a link into the app • Choose format (MP4 or MP3) and resolution/bitrate • File downloads in the background, lands inside an in-app folder structure the user can rename, move or delete &bu...
My custom e-commerce site is built on Laravel, not on Shopify or WooCommerce, and I need a sharp developer to tidy up a few pain points. First, a handful of pages are throwing 404s or directing to the wrong place. I’d like those links traced, corrected, and any underlying routing issues cleaned up so future content changes don’t break again. Second, page loads feel sluggish. I’ve spotted heavy database queries, un-optimised images, and a couple of third-party integrations that look chatty. I’d like you to profile these bottlenecks, refactor the queries, compress or lazy-load media where it makes sense, and audit the external calls so they only fire when truly needed. Deliverables • All broken links/pages resolved and verified • Average page load tim...
I’m looking for a small, no-frills tool that I can spin up on a Linux VPS and use to blast out a single message to every recipient listed in a CSV file. The workflow is simple: I upload the CSV, paste or type the message, press send, and watch the log as each username or user_id is processed. Core expectations • Runs headless on common Linux distros (Ubuntu/Debian preferred) • Leverages the unofficial Telegram API • Accepts CSV upload (one column of @usernames or ids) and sends the same text to each entry in sequence • Streams progress to stdout or a minimal web dashboard, then saves a completion report (sent / failed) to CSV or JSON Deliverables 1. Clean, well-commented source code 2. Step-by-step setup notes I can follow on a fresh server (Dockerf...
I’m looking for a technical freelancer to design and implement a reliable ChatGPT automation system using the OpenAI API. The goal is to capture tasks, notes, and decisions via text or voice and automatically push them into my task system (Apple Reminders preferred, or a robust alternative).
