Build Production-Ready Medical Al Web App (Next.js, Supabase, LLM)

I am an doctor building MedAudit IQ, a web platform for medical postgraduate exam prep (NEET-PG / INI-CET). We have validated the concept with 30 users. I need a developer to build the v1.0 MVP based on a detailed, production-ready PRD. The Tech Stack · Frontend & Backend: Next.js (React) / Node.js Serverless API Routes · Database: Supabase (PostgreSQL with Row Level Security) · AI Integration: Google Gemini API (Structured JSON outputs) Key Deliverables (Scope) 1. User Auth & Database: Setup Supabase Auth and create tables for Questions and User Mistakes. 2. Diagnostic Quiz UI: A clean, distraction-free interface for taking tests. 3. Gemini API Integration: A secure backend route that takes wrong answers, calls Gemini, and returns a strict JSON error audit (Clinical Pillars, Exam Traps). 4. Variant Caching: Pre-generate 3-5 retest questions per concept and cache them in Supabase to ensure zero latency for the user. 5. B2B API Endpoint: A secure, rate-limited /api/v1/audit route for future platform partners. Clear Expectations & Deliverables · Timeline: 3 weeks. · Budget: $500 USD (Fixed Price). · Milestones: 30% to start, 40% at Gemini API Demo, 30% at final handover. · Warranty: A 14-day bug-fix warranty after final handover. · Security Rules: API keys must NEVER be exposed client-side. All Gemini calls must route through the backend. How We Work Together · Communication: Daily quick updates via Upwork. Weekly milestone demo on Zoom/Loom. · Code Ownership: You will push code to a GitHub repository that I own. You must sign an NDA and IP Assignment agreement before starting. · No Scope Creep: The PRD is final for v1.0. New features will be built in v2.0. To Apply: Please reply with: 1. A link to a live application you built using Supabase and an LLM API. 2. Your estimated hours to complete this build. 3. Confirmation that you accept the $500 fixed price and milestone structure. I will share the full PRD v4.0 document with shortlisted candidates.
