We are a hotel using a specific electronic door lock. We need to integrate these locks with our Property Management System (PMS) to automate keycard management. The lock company cannot provide an API or documentation, so we need to determine the communication protocol and build a custom interface. Scope of Work: Analyze the communication protocol between the lock system and its hardware. Develop a software middleware/API to connect our PMS to the lock system. The interface must handle core functions: creating new keycards for check-in, extending access, and revoking access at check-out. Provide clear documentation on the protocol and the solution. Test the integration to ensure it is reliable. Dumps of Master Card, Guest Cards, Configuration Cards and Add Locks Card will be provided. Th...

I’m looking for an experienced Windows native developer (C++ / reverse engineering / performance optimization) to analyze and refactor an existing desktop application startup flow. The application currently performs blocking network checks during startup, which significantly slows down launch time and makes it dependent on an external service availability. Goals: Analyze application startup sequence Identify blocking operations (network / license / initialization) Propose and implement a faster startup approach (e.g. async checks, caching last valid state, or local test mode for development) Improve overall startup performance and stability Tech details: Windows desktop application Native executable (C++ / mixed native) Tools used: IDA / Ghidra Requirements: Strong experi...

I have already wrapped up all product design, UX, and UI work for my new Android app and now I need the engineering muscle to bring it to life. Your main mission is two-fold: first, build system-level battery-optimization enforcement so the app behaves responsibly in the background without being killed by Doze or aggressive OEM policies; second, hook the project into Firebase. On the Firebase side, the app must support Authentication and Realtime Database right out of the gate, with Cloud Messaging for push notifications and Remote Config for on-the-fly feature tuning. For sign-in flows, I only need email-and-password and Google Sign-In. You will be working from a clean, well-commented repository that already contains the complete UI layer. I’ll provide the Figma files, current Gra...

I’m building Mirai Album, a desktop application that lets photographers design complete wedding albums without leaving one streamlined workspace. The program must run smoothly on Windows 10 and Windows 11, install with a single click, and feel at home on modern systems. Tech stack You can take either route—Java (Swing/JavaFX) or Python (PyQt/PySide)—as long as the final EXE is stable and fast. I’ll supply brand assets and preliminary UI mock-ups; you focus on the engineering. Core feature set • Integrated photo-editing tools: filters & effects, precise cropping/resizing, and dependable red-eye removal, all updating in real time even with large JPEG or RAW files. • Intuitive page and spread layout with drag-and-drop, unlimited undo/redo, and liv...

I need a compact piece of code that can create an L1-eligible product listing on the Government e-Marketplace (GEM) portal. The sole focus is the “Product on GEM site” functionality— no user management, payment handling, or analytics at this stage. The script should: • Authenticate with my GEM account (I’ll supply sandbox credentials). • Push all mandatory product data— title, specifications, price, images— so the item appears in the catalogue and is flagged as the lowest (L1) offer when applicable. • Return the product ID or any response GEM provides that confirms the listing. Language can be Python, Node.js, or another mainstream stack if you can justify the choice. Keep the code clean, well-commented, and drop a short README...

I’m building a product, not a demo and not a quick MVP. I’m looking for a a small and strong team who wants to help build something foundational and stay involved, not someone who just wants to close a ticket and move on. The work is split into two tightly connected parts: 1) Code name - RAYA This is the core platform. RAYA is an AI orchestration system — basically the “brain” that handles AI workflows, task routing, logic, decision layers, and integrations. It’s not tied to one product. The idea is to build this once, properly, so it can power multiple products over time. Think platform first, product second. 2) Code name - LEO LEO is the first real product built on top of RAYA. It’s focused on jobs, talent, hiring workflows, 6 other field niche a...

I’m looking for experienced engineers who can step into an active code-base built with React on the frontend and a Node.js backend, keep everything running smoothly, and leave the code healthier than you found it. Most of the work revolves around maintaining the existing platform—troubleshooting production issues, refactoring brittle components, tightening test coverage, and slipping in incremental feature requests without disrupting current users. What you’ll actually tackle day-to-day depends on your strength: • Frontend specialists will focus on React component updates, state management fixes, accessibility tweaks, and performance profiling. • Backend specialists will handle Node.js services, REST/GraphQL endpoints, database queries, and deployment script...

I’m a newly minted Integration Engineer who wants to move beyond theory and get confident inside the Fiorano Integration Tool. To do that, I’m booking a focused, 60-minute video or voice session with someone who has real-world Fiorano experience and knows how to translate that knowledge to a beginner. During our call I’d like to walk through practical integration scenarios, then zoom in on the areas I find toughest—debugging, routing, selectors, XSLT flows, and the overall logic that ties a complete solution together. By the end of the hour I should not only understand what to click but why it matters in production. Key topics I need you to cover clearly: • Common debugging techniques • Routing configurations • Handling errors in flows After ...

Schwab API Execution Hardening – 2 Week Contract I’m completing a nearly finished Python trading system (“Hyperion”) and need a senior execution-focused engineer for final hardening and validation. This is NOT a strategy build. This is broker execution stabilization. System Context: • Schwab API integration • Cash account only • Single-leg options only • No spreads • No margin • GUI guardrails implemented (contract limits, capital caps, DTE filters, one position per symbol) • 80–90% complete Scope: • Validate OAuth refresh logic • Harden order submission (idempotency, duplicate prevention) • Confirm proper order lifecycle handling • Implement position reconciliation checks • Add structured logging &bu...

My Ruby (Rails) API usually answers in milliseconds, yet at unpredictable moments the same endpoints take seconds to return. Standard logs show no spikes in traffic, and CPU / memory look normal, so I suspect a hidden bottleneck—perhaps DB connection exhaustion, an elusive N+1 query, or a background job starving Puma threads. You will dive into the codebase, profile the request/response cycle, pinpoint the root cause, and supply a clean fix that restores consistent response times. Feel free to use rack-mini-profiler, New Relic, Scout, or your preferred Ruby profilers; the server runs Ruby 3.1 and Rails 7 on PostgreSQL. Deliverables • Diagnostic report summarising findings and root cause • Patch or pull request with the optimised code/configuration • Before-an...

I need a lightweight manual dialer that runs smoothly on Windows and faithfully records every call I make. The core requirement is simple: I enter a number, hit dial, and the application logs key details—number dialed, start & end time, and call outcome—into a clear, exportable file (CSV or similar). While contact management or speed-dial shortcuts might be nice down the road, for this first release I only want reliable call-logging baked in. Feel free to build in a modular way so extra features can be bolted on later without a full rewrite. Deliverable: a Windows-ready installer (or portable EXE) plus clean, well-commented source code and a quick read-me that shows me how to configure, run, and access the log. I’ll test by placing 10 sample calls; if all appear...

I need an experienced engineer to analyze and improve a high-demand online booking workflow so bookings can succeed reliably even under extreme traffic. I already have a working Playwright-based browser automation, but during peak demand all sessions currently land on a “high demand / unavailable” state. The goal is to improve success rate through deeper system understanding, better timing, and smarter flow control . The work involves analyzing booking flow and state transitions, understanding how availability actually appears during high demand (including delayed or staggered releases), improving timing, retries, waiting strategy, and navigation logic, eliminating race conditions and aborted navigations, and designing the automation to be long-running, reactive, and resilient ...

I’m seeking an expert who knows Cosmiol 5.5 inside out for a focused, one-time assignment. I’ll share the exact objectives with you once we connect, but the end goal is simple: walk away with a fully functional Cosmiol setup that does exactly what I need—no lingering bugs, no half-finished features, and clear documentation so I can maintain it later. Because Cosmiol’s workflow can get intricate, I’m counting on you to: • Analyse my current environment and quickly pinpoint what must change or be built. • Implement the agreed solution directly in Cosmiol 5.5, following best practices. • Validate every change with me in real time, making revisions until we hit the mark. • Hand over concise notes or a short screencast explaining what yo...

I’m overhauling the sign-in flow for my private messaging product and need an engineer who can implement a rock-solid, token-based authentication system. The goal is simple: on the web client a user scans a QR code from the mobile app, receives a short-lived access token plus refresh token, and stays logged in until they choose to unlink that browser. Scope of work • Build the complete QR-code handshake between the mobile app (already in React Native) and the web client (React + Node). • Issue, sign, and validate JWTs with advanced security: asymmetric keys, rotating refresh tokens, strict audience / issuer claims, TLS everywhere. • Automatic, silent refresh of access tokens before expiry without interrupting the user. • Server-side endpoint to terminate a ...

I’m ready to move an idea from concept to a working product and need a seasoned full-stack developer who can own the entire build. The core scope includes shaping the architecture, more details will be shared with potential freelancer

I need a lightweight Windows utility that I can drop onto any PC (USB-portable, no installer) and lock down three specific areas with a single master password: • block any executable I specify, • disable or hide every active sound driver so the system stays silent, • cut all internet connectivity on demand. AskAdmin already covers most of this, but it does not touch audio devices, so that gap is crucial. A simple “Enable / Disable” toggle behind the password is enough—there is no need for multiple user levels or activity reports. Deliverable: a standalone EXE (or similar) that runs on Windows 10 and 11, along with brief usage notes so I can add or remove apps, sound, or network from the block list.

I’m working on an STM32H7 design and I need the ST Acoustic_SL middleware added cleanly to my firmware so I can start experimenting with the Sound Localization feature right away. The CubeMX-generated project is already set up and building under STM32CubeIDE; what’s missing is a fully integrated Acoustic_SL stack (latest release) with all required dependencies, paths, and initialization code. Here’s what I’m expecting from you: • Import Acoustic_SL into the existing STM32H7 project and resolve every include, linker, and memory-map requirement. • Provide a minimal example (e.g., mic array capture + X-Y angle printout over UART) that shows Sound Localization working on real hardware. • Supply a short read-me that explains any CubeMX tweaks, middl...

My Python-based automation bot just lost its first head-to-head race against a competitor. I noticed a clear lag, even though I’m already steering clear of packet manipulation tricks and want to keep it that way. Execution speed is my top priority, and initial profiling points to the data-processing routines—mainly the window-reading layer that gathers live information before each decision cycle. Here’s what I need: • A careful code review focused on the sections handling window reads and subsequent parsing. • Concrete refactoring or micro-optimisations that shave milliseconds without compromising detection accuracy. You’re welcome to propose techniques like caching, vectorised operations, Numba/Cython acceleration, asyncio or threaded batching—a...

I have the original Turbo Pascal source code of a classic dial-up BBS. I now need it refreshed for today’s networks and hardware while keeping the old-school spirit intact. The first priority is a clean build that runs natively on Ubuntu (64-bit). After that, I will also want Windows 11 and ARM binaries, so please structure the project with cross-platform portability in mind from day one. Core objectives • Eliminate all pre-2000 date logic and make the code fully Y2K-compliant. • Replace the COM-port/modem routines with an integrated Telnet server so users can connect over TCP/IP without external helpers. • Modernize the interface where it matters for functionality—clearer menus, smoother navigation, and optional theme hooks—while respecting the ret...

I need an experienced Erlang/OTP developer to extend an already-running application by adding a brand-new feature focused on improved data handling—specifically, real-time text replacement. The current codebase is stable but offers only limited, batch-style substitution; I now want replacements to happen on the fly as data moves through the system so downstream processes always receive the updated stream without noticeable latency. The job involves diving into the existing OTP supervision tree, identifying the modules that touch the data pipeline, and rewriting or adding functions so dynamic replacement rules can be injected, updated, and applied immediately. Concurrency, hot-code upgrades, and fault tolerance all matter here, so I am looking for someone genuinely comfortable with g...

Project Overview We would like you to develop a training support tool that displays recommended actions on the UI by mirroring the "xPoker" smartphone app's club screen to a PC using ApowerMirror and reading the screen information. * Automation of operations (clicking, bet input, etc.) will not be performed. * Completely local operation (no server or cloud). --- Intended Use • Practice tool for regular poker • Supports up to 8-player tables (MAX 8) • Supports simultaneous play on 3 tables (Note: 3-table play involves sliding between screens, not simultaneous display on one screen) --- Operating Environment and Prerequisites • OS: Windows 10 / 11 • Mirroring: Using ApowerMirror • Operates entirely on a local PC • Language: Python or othe...

I’m after a lightweight Electron + React desktop application whose sole purpose is to collect user input. A single-window interface is fine—as long as it captures plain text fields and a small form submission flow smoothly. There’s no need for data display dashboards or file-management tools; everything can live locally, with no complex backend. Here’s what I need: • An Electron-React scaffold (electron-forge, Vite, or your preferred tool) with clean project structure • Minimal UI: text inputs and a submit action handled in React state • Final Windows build (.exe or installer) plus a script so I can reproduce the build • Clear README covering setup, development, and packaging steps I’m working with a limited budget, so lean on prove...

Our Python-based platform has been in production long enough to accumulate a handful of thorny issues. I want a fresh, senior-level pair of eyes to go through the codebase, diagnose what’s really happening, and bring the system back to a stable, performant and secure state. Scope of the audit • Security: probe for obvious misconfigurations, insecure dependencies, injection risks and any surface that could be exploited. • Performance: profile critical paths, highlight bottlenecks, and suggest optimisations that translate into measurable speed-ups or lower resource usage. • Code quality: evaluate structure, readability and test coverage; recommend refactors that reduce technical debt. Highest priority fix Functionality issues come first. Anything preventing cor...
