Kernanforderungen • Echtzeit-Synchronisation:  – Produkte (Artikelstammdaten, Preise, Bestände)  – Bestellungen inkl. Status-Updates • Technologie: Nutzung der Business Central REST-API als zentrales Gateway; auf Shopify-Seite gern native REST-Endpunkte oder GraphQL, solange die Lösung konsistent bleibt. • Modularer Aufbau, sodass künftige Erweiterungen (z. B. Kundendaten) mit minimalem Aufwand eingebunden werden können. • Sauberes Fehler-Handlin...

I need a single Google Sheet that lets me type a Home Depot or Lowe’s model number in one column and, without any extra clicks, instantly fills the rest of the row with: • Brand • Product title • Full description • Current price on Home Depot • Current price on Lowe’s • Main image URL I’d like the sheet to refresh these fields automatically once every day so I always see up-to-date pricing. I’m happy to use the HASData API (or another service if you can show a better option), and I’ll cover the subscription cost myself; I just need you to wire everything up in Apps Script or another reliable method so the calls stay within API limits and don’t break if the catalog grows. Deliverables • A Google Sheet t...

I’m rolling out a new generation of eco-friendly EV charging stations and need a full-featured management platform built from scratch. Here’s what the first release must do for me: • Energy usage monitoring for every session and charger • Remote control—start, stop, reboot and schedule charging • Secure user authentication Role-based access is essential. Administrators configure the network and view global analytics, end-users simply authenticate and charge, while maintenance staff receive real-time diagnostics and alerts. The platform must also talk seamlessly to our existing energy-management system through open, well-documented APIs so we can optimise load and incorporate on-site renewables. REST/JSON is preferred, but I’m open to proven alterna...

I’m forking and need a seasoned TypeScript engineer who is totally at ease working Git-first and can dive straight into a Nostr codebase. The immediate goal is to introduce a suite of non-public features around improved listings and, above all, a powerful personalised content-suggestion layer. Scope • Extend the existing front-end and back-end (TypeScript, React, Node) with the new private listing modules I will outline in Figma and Notion. • Build a recommendation engine grounded in socio-psychology principles rather than the usual collaborative or content-based filters. I will supply the research notes and sample scoring model; you will translate them into production code, unit tests, and API endpoints. • Keep everything behind a feature flag so the public fo...

Key Requirements: Scalable cloud-based backend architecture Secure user authentication and account management Media storage and optimization (photos, video, audio) Stripe integration for e-commerce checkout Automated unique QR code generation tied to profiles Short, engraving-friendly URL system Public memorial pages (SEO optimized) Robust admin dashboard with: User management Order management &am...

We have developed two Python scripts to prepare VTT files (*.vtt) for translation and another to prepare them for delivery to the client. The first script combines segmented text for translation. The second script re-splits the translated content into properly timed captions for delivery. Currently, if a project manager wants to use the scripts, they need to email the files to the script owner, who manually runs the first script and returns the processed files to the project manager. The project manager then continues with the workflow. Once the translated content is finalised, the project manager emails the files back to the script owner to run the second script, and the script owner sends the processed files back to the project manager for delivery. We want to implement a solution tha...

I’m building a lightweight MVP that lets independent cafés run a fully automatic, card-linked loyalty programme without issuing separate cards or apps. The core of the job is a secure backend service that: • Listens to Square and SumUp webhooks / APIs, fingerprints the payment card (never the full PAN) and recognises returning customers. • Increments a visit counter and, when a customer hits the reward threshold, instantly triggers the reward logic. • Fires an SMS through Plivo to let the guest know they’ve just earned, for example, a free coffee. What I’ll look for in the finished work 1. Clean, well-documented code (language and framework are up to you as long as it’s reliable and easy to maintain). 2. Clear setup instructions a c...

I'm looking for an experienced full-stack developer to implement the MVP end-to-end. I'll need a video call, so no scams here. Overview Clients submit coding tasks through a store-like request system. Each request becomes a project with clear lifecycle tracking, communication, time tracking, and weekly billing.

I already run on the WhatsApp Business API and now need it properly connected to Meta so I can handle both automated replies and bulk messaging from one place. Here is what I expect: • Map my current WhatsApp Business API number into Meta Business Manager, verify it, and activate webhooks. • Build out the automated flow reply I have in mind so it can answer customers instantly—this includes template approval inside Meta and any required server-side logic. • Enable a straightforward method for sending large-volume marketing broadcasts that stays within Meta’s policy limits (24-hour window, opt-in, template use). You may use Node.js, Python, PHP or another language you’re comfortable with, as long as the final solution is documented and ready for m...

I need a web-based hotel booking platform where travelers can type a U.S. ZIP code, instantly see nearby hotel options, and complete the reservation at the best agent-only rate by entering a valid IATA number at checkout. The core build must: • Pull live availability, pricing, and booking capabilities through direct API integrations with Amadeus, Sabre, and Travelport. • Offer traveler-facing search filters for price range, star rating, and specific amenities. • Display results sorted by distance from the entered ZIP. • Securely process the booking, verify the IATA, and return confirmation details in real time. I’m looking for a clean, responsive interface, clear documentation of each API connection, and deployment on a cloud host of your choice. Onc...

I need a clean, self-contained FastAPI microservice that accepts an uploaded JPEG or PNG, automatically traces the outer contour of the visible subject, expands that shape by a configurable offset, and returns the resulting cutline as an SVG file. Auto-outline detection is the single most important processing step; edge smoothing and colour tweaks are nice-to-haves but not required for this phase. Here’s the flow I have in mind. A user hits /outline with a multipart upload, the API queues the image, runs the outline routine (OpenCV, scikit-image, or any library you prefer), inflates the path by the requested number of pixels or mm, then streams back plain-text SVG. A second, optional endpoint /health is enough for monitoring. The service must comfortably handle images up to roughly ...

Initial Focus 1) AI Influencer Factory Create/manage multiple virtual influencer personas (style, voice, strategy), generate text/image/video content, run publishing pipeli...

I’m building an Android-only application and need a clean, secure login flow that relies on one-time passwords sent strictly by SMS. Users will enter their phone number, receive the code, and gain access after successful verification—no usernames or emails involved. You’ll be responsible for wiring up the full authentication cycle, choosing a reliable SMS gateway, and writing the Android code (Kotlin or Java—your call) that: • accepts the phone number, • triggers the SMS OTP dispatch, • validates the returned code with sensible expiry and limited retries, • handles resend logic, and • stores / refreshes session tokens once the user is verified. Deliverables must include the documented source code, any backend or cloud function n...

We are looking for a developer to build a scalable web platform similar to WhatsForm. The core objective is simple. Users should be able to create a form, share its link, and when someone submits the form, a pre-filled WhatsApp message should open to a predefined number while the submitted data also gets saved automatically in the user’s connected Google Sheet. The platform should allow users to build basic forms with fields like name, mobile, email, dropdown, checkbox, and text inputs. Each form should generate a shareable public link. On submission, the system should redirect to WhatsApp with the filled data in message format (no need for auto-send via API in Phase 1). Users must be able to connect their Google account and select or create a sheet where all responses are stored w...

This project entails building a generative-AI web application that runs entirely on OpenAI GPT and delivers a smooth, real-time, text-based chat experience. The frontend must be responsive so users on desktop or mobile feel no friction, while the backend handles dynamic prompts, keeps short-term conversational context, and lets me fine-tune how the model responds. Core functionality • Secure user authentication (log in / sign-up) • Drag-and-drop or button-based file sharing inside the chat window • Conversational memory so the AI remembers context during a session and resets cleanly when required Behind the scenes the app should: • Call the OpenAI GPT API efficiently, batching or streaming tokens where it makes sense to keep latency low • Store transien...

I am assembling a full-stack solution that ingests live financial databases, open-source macroeconomic feeds, and user-submitted figures, then turns all of it into forward-looking insights. The core of the product is an AI layer that delivers predictive analytics and runs configurable scenario simulations; the results need to surface instantly inside an intuitive web dashboard where users create and save their own reports and visual layouts. What I need from you is an end-to-end build: • Data layer – connectors that automatically pull structured and unstructured data from the three source categories above, plus a storage design that can scale as historical records grow. • ML & simulation engine – time-series forecasting models, Monte Carlo or agent-based simula...

I need a mobile app that can create and print two identical copies of every bill—one for the customer and one for the driver—using a TVS thermal printer. Each bill will carry our company logo and a system-generated, unique barcode. When that barcode is scanned with any standard phone camera or scanner, the duplicate copy of the bill must open immediately on the user’s device. The workflow is simple: fewer than twelve fields are filled in for each transaction, the app saves the data, produces the two printouts, and stores a cloud-accessible version linked to the barcode. A straightforward username-and-password login keeps everything secure. Key points the finished solution must cover: • Seamless Bluetooth or USB communication with the TVS thermal printer (other bran...

I am seeking an expert WordPress plugin developer to build a professional-grade, cross-browser cookie cleaner that gives administrators granular control over which specific cookies are deleted when users log out. This is not a simple "delete everything" plugin—existing solutions fail because they either rely exclusively on the Clear-Site-Data header (which does not work on Safari, iOS browsers, or Edge Legacy), or they lack a proper admin interface for selective deletion, or they cannot handle HttpOnly cookies (like WordPress authentication cookies) which JavaScript cannot touch. I need a four-layer hybrid solution that: (1) sends the Clear-Site-Data header only to supporting browsers (Chrome, Firefox, Edge Chromium), (2) performs server-side PHP deletion of HttpOnly cookie...

I need a reliable solution that can pull data from LinkedIn and insert it straight into a database I specify. The core requirement is the automated transfer—once the tool finishes scraping, every captured field should already be sitting in the database ready for queries and reporting, no manual copy-paste. You’ll advise me on the best approach to authenticate, respect rate limits, and minimise the risk of blocks while still collecting the typical profile-level details (name, headline, company, location, experience, education, skills and anything else you can legally obtain). I will confirm the final field list before you begin. Key objectives • Build or configure a scraper / API wrapper that logs in, navigates to each target profile and captures the agreed-upon fields ...

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: ...

Our mobile app is already live on a staging domain, built with React Native, Node.js (Express) and MongoDB. I now need a full-stack developer who can dedicate the next seven days to finish three key items and move everything to our official domain. 1) Community auto-membership Every new registrant should be placed into the correct in-app community automatically when their professional email domain matches one that we map in the database. No manual steps—just detect, assign and save. 2) OTP email verification Before the first login the user must confirm ownership of that professional address. Generate a one-time six-digit code, send it via email, and allow a single attempt window with proper resend limits and expiry logic. 3) Production deployment The existing backend and adm...

I have a fully-functional ERP written in core PHP with a MySQL backend. The next milestone is an Inventory Management module dedicated exclusively to stock tracking. No supplier or order features are needed at this stage.

The developer should build a cross-platform AI-powered IT Help Desk agent and management system that supports Windows, Linux, and macOS. The system must include a backend API (preferably in Python FastAPI or Node.js) to handle ticket management, device registration, and command distribution, along with a secure database (PostgreSQL) and an optional vector database for AI knowledge retrieval. The agent itself should be written in a compiled language like Go for cross-platform deployment, capable of registering devices, reporting system info and heartbeat, detecting missing patches, restarting services, and executing safe commands remotely. The AI component should analyze incoming IT tickets, automatically suggest fixes, and optionally execute auto-remediation commands when safe. All communi...

• Description We have a small Python script which needs to be put on the server-side as an API. Excluding the GUI code and comments, the script has about 750 lines. You will be given a VPS, which the API will allow downstream applications to call the engine for data comparison. We need multiple real-time endpoints for downstream applications. For testing purposes, we will set the maximum to 3 for now. Ultimately, it can be scaled to an unlimited number of real-time comparisons. I suppose we will have multiple copies of the comparison code on the same/different servers, but with three REST API endpoints. Hence, the Python script will be split into server and client-side code. As there are multiple data points to be compared with, we are thinking that the web app will first initiate...

I need a series of scenarios that connect ShipHero’s API with several online storefronts. The focus is on three core workflows: • Order processing – every new or updated order placed in the storefront must appear in ShipHero in near real-time. • Inventory management – stock level changes inside ShipHero should automatically update the corresponding product in each store. • Shipping updates – when ShipHero produces a label or tracking event, that information has to flow back to the customer’s order in the store. I already have the official ShipHero API documentation and can give you the credentials right away. Each storefront (think Shopify, WooCommerce, Magento, and others we decide on) will need its own well-named, modular scenario so I ...

Scope of Work Chat Interface (Front-end): A clean, user-friendly chat bubble/window on our website where students can type questions. It must support "streaming" (where text appears word-by-word) so users aren't waiting on a loading screen. The Bridge (Back-end): Develop a secure middleman (API) that takes the student’s question, sends it to OpenAI or Google Gemini, and brings the answer back to the website. AI Logic: Set up the system so I can easily toggle which AI mode...
