    My goal is to turn a manual Google Sheet into a fully self-updating workspace. The sheet must pull fresh data automatically and place it in the correct tabs without my intervention. The data sources in scope are: • REST/JSON APIs • Web pages that need light scraping • A small internal SQL/MySQL database Whether you prefer Google Apps Script, AppSheet, or a hybrid approach, the final build should remain lightweight and easy for non-technical teammates to adjust. Key expectations 1. Time- or event-driven triggers that fetch, parse, and write data into designated ranges. 2. Well-commented code plus a concise setup guide so I can change endpoints or column mappings later. 3. Basic error handling with email or on-sheet alerts whenever a source is unreachable. 4. ...

    I have a live pitch coming up and need temporary access to a working Hermes AI instance that I can brand as a “virtual assistant” for Instagram. During the demo I will connect my own Instagram account, so the setup must let me authorise the account quickly—either through the official API or a secure webhook you already have in place. The one feature I absolutely must show is real-time message handling: as soon as a follower sends a DM, the agent should generate an intelligent reply that I can display to the client. I’m not planning advanced analytics or auto-posting for this session; conversational response is all that’s required. Here’s how I see it working: 1. You give me short-term access (cloud URL or container) to your ready-to-go Hermes AI ...

    I need a full-scale crawl of more than ten million Walmart product pages focused strictly on two elements: the complete product description (title, bullet points, long form copy, specifications) and every image available in the gallery for each SKU. Price, availability, reviews, or other metadata are not required at this stage, so the scraper can concentrate on content-rich fields and high-resolution media. The raw HTML is not necessary; I would like the text cleaned and structured (JSON or CSV) and the images downloaded or stored as direct links, organised by SKU. Because of the size of the catalogue, I expect the solution to run in parallel—cloud-based orchestration with Scrapy, Python requests, Playwright or a comparable headless browser is fine as long as it can bypass typical a...

    (The below was rewritten by ai but I believe it to be fairly accurate.) I run a WordPress GeoDirectory site that relies on a custom “Events” post type. Each morning, I open six country-specific Facebook pages, download the latest post images and text, and seed my directory with a handful of new event drafts. It works—but it is entirely manual and I plan to add many more Facebook pages, so the process has to be automated. The part I cannot crack is the Facebook data scraping itself. I have Hermes Desktop installed and have experimented with a few public “scraper” scripts as well as Apify, but none delivered a reliable, repeatable stream of image and text content. Once I have clean data in hand, I’m comfortable pushing it into WordPress through GeoDirect...

The project will be complete when: • The app builds in Android Studio (Kotlin / Java) with the new API level and no deprecation or permission warnings that block release. • A release build is accepted by the Google Play Console without policy or API‐level errors. • All storage operations succeed against my current GC...

    I want to automate my wedding invitations through the WhatsApp Business API. The flow I have in mind is simple, yet has to feel personal: • Each guest receives a WhatsApp message— not a PDF or static flyer— but an actual chat message that carries their name, the date, time and venue, plus a sleek, modern image that matches our overall design. • The message should ask whether they will attend. A quick-reply or any similarly friction-free option that records a Yes / No is ideal. • A unique QR code must be generated for every confirmed guest. That code will be their digital “ticket” at the entrance and needs to scan reliably on standard readers. From your side I expect: 1. End-to-end setup of the WhatsApp Business API (green-tick account alre...

    I’m planning to roll out a small-footprint Identity and Access Management editor that my clients can use to create, view, and adjust their own policies without touching the underlying infrastructure. At its core the tool should let an administrator sign in, browse existing users and groups, and then add, change, or revoke permissions through an intuitive interface. Although I have not finalised the target environment yet, I want the architecture to stay flexible enough to plug into common cloud stacks such as AWS, Azure, or Google Cloud later on. If you already have presets or libraries that handle role definitions, access-control statements, or audit logs for any of those platforms, feel free to mention them in your approach. The deliverable I’m looking for is a working ...

    I have an Excel file containing more than 5000 customer records that need to be added to Viber. I don’t just want one large broadcast list—I need these contacts neatly segmented into multiple groups so future messaging remains targeted and manageable. Here’s what I’m after: • Cleanly import every entry from the Excel file into Viber without triggering number-block issues or spam flags. • Create and name the groups based on criteria we agree on (e.g., location, purchase history, or any other filters you recommend). • Provide a repeatable method—whether that’s a step-by-step guide, a small script, or automation using the Viber API/desktop tools—so I can run future imports on my own. • Verify that each group shows the correc...

    I need a complete, in-house GPS tracking solution that can comfortably serve well over 50,000 vehicles without relying on the off-the-shelf Chinese systems we currently use. The project covers three client surfaces—Web, iOS, and Android—plus a robust back-end able to ingest, process, and store high-frequency location data in real time. Core functionality must include: real-time vehicle tracking on dynamic maps, configurable geofencing with instant alerts, and long-term historical data retention ready for playback or bulk export. Alerts are critical: push, SMS, and email should all be configurable through an easy rule engine. I also need an integrated payments & billing module so we can manage subscriptions and automatically invoice clients. An open, well-documented API lin...

    I’m looking for a streamlined way to reach new finance professionals on LinkedIn without living in my browser all day. The end-goal is simple: • Automatically send personalised connection requests to prospects who clearly sit inside the Finance industry. • Once they accept, trigger a short, customisable follow-up message sequence—ideally with delays I can tweak. Please build a small, reliable solution that can pull Finance-related profiles (for example via Sales Navigator filters, CSV uploads, or another compliant method), queue the invitations, and then handle the post-accept messaging. I’m open to your favourite stack—Python + Selenium, Puppeteer, PhantomBuster, or a SaaS you already trust—so long as it respects LinkedIn limits and keeps my...

    My goal is to compile all of my sales information from our e-commerce platform into one clean, reusable dataset. I already have platform access and the required permissions; what’s missing is a reliable process that extracts the raw order data, standardises the fields, and delivers it in a format my team can filter, analyse, and update whenever we need. The platform’s API is available, so scripting in Python, pulling through a tool like Power Query, or another API-friendly method is perfectly acceptable—whichever gives us accurate, complete results. Because there’s no strict deadline, I prefer a well-documented, future-proof approach over a rush job. Deliverables should include: • A consolidated CSV or Excel file containing every transaction to date (order ...

    I have a set of software specification documents that will be shared with a client during an upcoming meeting, and I need them rendered into clear, professional English. The material is strictly technical—feature descriptions, data-flow explanations, and API notes—yet it sits at a moderate depth of detail rather than deep-dive, code-level complexity. Your task is straightforward: keep every concept intact, preserve any diagrams or variable names exactly as they appear, and use terminology familiar to developers and product managers. Fluency alone is not enough; you should be comfortable with phrases such as REST endpoints, data models, latency metrics, and other common software-spec jargon so the translated version feels native to a tech-savvy reader. Deliverables • A po...
