    I’m ready to turn a fresh social-media idea in...clips before publishing. A swipeable feed, real-time notifications, and solid profile management should anchor the first release, with architecture flexible enough to layer in cross-platform reposting later. I’d like the build on a scalable cloud stack—AWS, GCP, or similar—paired with a modern UI framework such as React (web) and React Native or Flutter (mobile). Clean, well-documented REST or GraphQL APIs are essential, as is secure authentication and basic moderation tooling out of the gate. Deliverables • Design and Wireframes Responsive web application • Native-feel iOS and Android apps from a shared codebase • Robust backend for media storage, auth, and moderation • All source c...

Whenever new inventory lands in the warehouse, a sale reduces available quantity, or a manual adjustment/return is logged in ACME, the exact stock level must instantly reflect on every Shopify product page without delay. Your job is to design, build, and deploy this two-way integration. My team can expose or consume REST/GraphQL endpoints on the ACME side, and I can generate API credentials in Shopify. Webhooks, polling safeguards, or a lightweight middleware layer are all acceptable—as long as every trigger above updates Shopify in real time and survives high-volume traffic.

    I have a mature JavaScript / Node.js codebase that now needs robust API connectivity. The goal is to wire in several external services—some exposed as classic REST endpoints, others as GraphQL—so the application can consume, transform, and surface that data seamlessly to the front-end. Here’s what I need from you: • Analyse the existing structure, identify the best touch-points for new service layers, and keep everything idiomatic to Node.js (Express, middleware, async/await). • Build out the integration layer for both REST and GraphQL calls, including token management, retries, and intelligent error handling. • Return clean, typed responses (TypeScript definitions or JSDoc) so downstream modules stay type-safe. • Write concise u...

    My esports tournament platform needs a thorough penetration test completed within four days. The stack combines a Supabase/PostgreSQL back end, REST/GraphQL-based APIs, user accounts, an admin console, and a wallet that handles deposits, withdrawals, and payment-gateway traffic. Primary focus is the payment gateway and wallet layer, yet I still want every public or privileged surface probed against the full OWASP Top 10 as well as common esports-specific attack patterns. That includes: authentication and authorization flows, admin privilege escalation, API abuse, IDOR, SQLi, XSS, insecure file uploads, exposed secrets, and verification of Supabase row-level security. Attempted manipulation of balances or tournament results is welcomed if it highlights a weakness. When the engage...

    ...familiar is essential so people can focus on their conversations. Core scope • Cross-platform build (native, React Native, Flutter or similar) • Secure authentication and profile basics adequate for messaging (full profile or news-feed layers can wait for later phases) • One-to-one and group chat, including text, emoji, images and short clips • Cloud-based, scalable backend with REST or GraphQL APIs • Admin panel or simple dashboard for user management and basic analytics • Brief technical documentation and source code hand-over Acceptance criteria 1. Both iOS and Android app bundles install and run without crashes. 2. Users can register, log in and send/receive messages instantly over Wi-Fi and mobile networks. 3. Push notificati...

    ...on small-to-mid sized mobile and web app ideas in the evenings and weekends, yet the queue keeps growing faster than I can ship. To keep momentum high, I’m looking for an extra set of skilled hands that can jump straight into feature tickets or green-field proofs-of-concept across both stacks. What will keep you busy: building and polishing cross-platform mobile screens, wiring them to REST or GraphQL back-ends, tightening up a responsive web view, and occasionally adding server-side glue in Node or Python so the front end has exactly what it needs. Clean Git habits, thoughtful pull-request comments, and an eye for performance are a must because every minute saved here equals more spare-time creativity for me. When you reach out, put the spotlight on your experience&mdash...

    I need a single, unified system that keeps every stakeholder in a pet...the stack must support live GPS feeds (Google Maps API, Mapbox, or similar) and be flexible enough for future native-app wrappers. Clean, modular code and clear API documentation are essential so the system can grow as volume increases. Deliverables • Working web application with separate role-based dashboards • Source code in a private repo, install/run instructions, and documented REST/GraphQL endpoints • Database schema and migration scripts • Two-week warranty period for bug fixes after hand-over Acceptance is complete when I can create a shipment, assign it to a test driver, see the pet move on the map, receive health updates, and watch notifications arrive in a customer test a...

    ...advantage of its relational strengths, indexing, and security features. Authentication should support registration, secure login (JWT or similar), password recovery, and role-based access. The system must scale easily as new user types are added. On the integration side, I will connect to both internal endpoints and external third-party services, plus at least one payment gateway. Clean REST (or GraphQL if you prefer) documentation is essential so the mobile team can consume endpoints without friction. While I am open to frameworks—, NestJS, Django, FastAPI, or another proven stack—the codebase has to be well-structured, fully commented, and delivered via Git. Deliverables • Source code with README and environment setup • PostgreSQL schema/migrations &bu...

    ...application for nurseries and primary schools and I need the whole solution to be driven by Django. The key point is that every user-facing feature—whether it eventually ships on iOS, Android, or both—must talk to a clean, well-documented Django back-end that you build. Here is how I picture the collaboration: • Architecture – Django 4.x (or latest stable) as the core back-end, with REST or GraphQL endpoints. – Secure authentication (parents, teachers, admin) and role-based access baked in from the start. • Mobile front-end – You are free to choose React Native, Flutter, Kotlin, Swift, or any other framework you are comfortable with, as long as it integrates smoothly with the Django API. – The UI should remain int...

    ...mobile audits. 2. Secure registration, login, and role-based access control. 3. Intuitive admin dashboard with bulk upload for course assets. 4. Student dashboard showing enrolled courses, progress percentage, and upcoming deadlines. 5. Discussion boards tied to each course or module. 6. Assessment engine supporting timed quizzes, automatic grading, and score storage. 7. Clean REST or GraphQL API layer so future mobile apps can plug in easily. 8. Documentation covering environment setup, deployment, and basic admin tasks. Acceptance criteria • All listed features work on Chrome, Firefox, Safari, and Edge, both desktop and mobile. • Page load <3 s on a 4G connection with typical course assets. • Code is pushed to a private Git repository with...

    ...through web forms. • Optional hooks for historical move data or live market rates should be left open but not hard-wired, so the architecture must remain modular. Tech expectations A lightweight front end (React or similar) can sit on top of a Python/Node microservice that hosts the model—TensorFlow, PyTorch, scikit-learn or whichever framework you feel is best for fast iteration. Clean REST or GraphQL endpoints are essential, and everything should be containerised for easy deployment. Deliverables • Customer-facing responsive form that feeds data to the model • Trained price-estimation model with documented feature set • Inventory-management dashboard with CRUD, search and export functions • Source code in a private Git repo, install ...
