MERN Developer Needed to Upgrade Gift Store MVP

I have a “Gift Store” web app MVP built with the MERN stack. The current version has basic UI and product pages but no AI integration yet. I am looking for a MERN developer who can refactor, improve, and polish the app, and prepare it to work smoothly with an AI recommendation API.

Responsibilities Review the existing MERN codebase and suggest improvements to structure, performance, and maintainability. Upgrade the UI/UX to look modern, clean, and responsive (desktop and mobile). Implement or refine backend APIs (Node/Express) for products, users, and the AI recommendation endpoint. Integrate with the AI API (provided by a separate AI developer) and handle loading states, errors, and results elegantly. Optimize for performance (caching, pagination, image optimization) and basic security best practices. What I Expect From You Strong experience with React, Node.js/Express, MongoDB, and REST APIs. A good eye for UI/UX and ability to implement clean, reusable components. Comfort integrating third‑party or custom APIs into React frontends. Clean Git practices and clear communication. Important – Show Me Your Skill In your proposal, include: 2–3 specific improvements you would make to my current Gift Store (for example: layout changes, component structure, routing, state management). How you would design the page and flow where users input their info and see AI recommendations. A rough 1–2 week plan (milestones) to refactor the MVP and integrate the AI endpoint. Preferred Qualifications Previous e‑commerce or dashboard projects in MERN (please share links or GitHub). Experience with modern styling solutions (Tailwind CSS, styled‑components, etc.). Experience working alongside backend/ML specialists.

Unreal Engine + Pixel Streaming + Full Platform Integration

We are a technical team and we handle all technical solutions and decisions ourselves. We are not looking for an architect, a planner, or someone else to define the system for us. What we need is an execution-focused engineer who can help implement the website strictly according to our requirements. This project has very strict verification requirements. There are eight platform development contracts based on the same principle; this is just the first one. We need to deliver a multi-role platform based on (state-machine driven + Stripe payments/escrow + ad bidding + 3D digital humans via pixel streaming).Using low-code + modular composition, we are building an international platform. It must be explicitly stated that this is not an MVP. A.Deployment & Infrastructure(Must be assembled and built on the Fly.io platform) 1) The platform must run on (frontend/backend, jobs/queues, WebSocket/WebRTC services as needed). 2) Proper logging/monitoring/alerting is required, including alerts for third-party integration failures and cost/usage anomalies. B.Core Requirements (Important) 1) Multi-role / four portals: end users, service providers, maintenance staff, and admin portal (different permissions and flows). 2) Critical business flows must be implemented using a state machine / state-driven architecture (no “skipping steps”): order → payment → escrow/split → fulfillment → acceptance → settlement → refund/dispute, with full traceability, rollback rules, and audit logs. 3) Payments: Stripe (payments, payouts, webhooks). Must handle idempotency, webhook replay protection, and concurrency-safe state transitions. 4) Automation / orchestration: n8n (or similar) as the workflow hub, connecting Supabase, payments, notifications, ads, and digital humans. 5) Conversational guidance: use Botpress (or similar tools) for conversations + next-step actions. 6) Advertising: creative management + delivery configuration + analytics; ad slot bidding/auction (e.g., Prebid.js / RTB model). Bidding logs must be retained and auditable. 7) Multilingual: UI/content must support multiple languages and integrate language detection and translation APIs. 8) External widgets / external entry systems：iframe / JS SDK / external components with controlled internal core logic. 9) Risk control mechanisms: rate limiting, switches, circuit breakers, fast shutdown without impacting payments) 10) 3D digital human system (Unreal Engine Pixel Streaming): 10.1.) MetaHuman + Unreal Engine for creating 3D digital humans. 10.2.) Pixel Streaming (WebRTC) to stream UE video to web/mobile clients. 10.3.) A unified control interface to switch avatars/actions and drive lip-sync via TTS audio, integrated with state-machine-driven guidance flows. C.Execution responsibility (mandatory) 1) This project must be completed independently by you personally. We do NOT accept teams, outsourcing, temporary staffing, or task splitting. 2) This requirement exists purely for commercial confidentiality reasons. 3) If the project cannot be completed by one individual, please do not proceed. D. Price and maintenance terms (fixed) Project delivery price: USD 3,000 (fixed) Post-launch maintenance: - USD 100 per month (fixed) - Includes system stability, critical bug fixes, security updates, and environment handling - No unilateral price increase is allowed - Any adjustment requires written mutual agreement If your pricing expectation is significantly higher, or if you cannot accept these terms, please do not contact us. E.Delivery time: 1) For an experienced and skilled engineer, under normal circumstances, the full project should be achievable within two months. 2) In addition, we have a clear requirement that within an earlier phase of the timeline, a runnable pilot version must be delivered. This pilot version is not the final completion, but it must already be in a stable, operable state and able to enter trial operation. 3) During the trial operation, we will identify issues, validate stability, and make necessary adjustments, so that the final delivery can meet the required quality standards. F. Please reply with: 1) Similar projects you have delivered (if possible, provide links/demos). 2) Recommended architecture and service decomposition. 3) What materials you need from me to proceed (execution step flows, required module list, etc.). 4)phased timeline, rough price range.
