Experienced React + Supabase Developer Needed — UK Care Tech (Fixed Price MVP Build)

React + Supabase Developer Needed — UK HealthTech SaaS MVP (Fixed Price) About the project: I am the founder of a registered UK technology company (Birmingham, England) building a health and social care SaaS platform for UK supported living providers. The product is currently at MVP stage with an established pilot programme underway. This is a production-grade build, not a prototype. The code will be owned by Nucain Ltd so clean, documented, and maintainable code is essential. Full project details, screen specifications, and database requirements will be shared under a Non-Disclosure Agreement after initial screening. What we need: An experienced React + Supabase developer to build a web application with: * 6–8 screens * 3 user types with different access levels * Supabase Auth with Row Level Security on all tables * Server-side time logic (fetching server time from Supabase — NOT device clock) * Supabase Edge Functions or pg_cron for automated background tasks * Responsive design — mobile and desktop * Vercel deployment * Tailwind CSS GitHub repo and Supabase project must be set up under Nucain Ltd accounts from day one. Payment structure: Fixed price. 3 milestones — 30% / 40% / 30%. Full milestone details shared after NDA is signed. You must have: * GitHub profile with deployed React projects I can view live — mandatory, no exceptions * Proven Supabase experience including Auth and Row Level Security * Ability to implement server-side time logic * Experience with Supabase Edge Functions or pg_cron * Strong English communication — clear updates at every milestone Before we hire, we will give a paid test task Every shortlisted candidate will complete a small paid technical test before being hired. The test directly relates to the core technical requirement of this project. Details shared at shortlist stage only. To apply, please include: 1. Your GitHub profile link 2. One live deployed React + Supabase project URL 3. A brief answer (3–5 sentences): How would you implement a feature where a form field only appears during a server-defined time window in React + Supabase, using server time, not device time? 4. Your fixed price quote and estimated timeline in weeks Applications without a GitHub link and a live project URL will not be reviewed. IP & Confidentiality: All code produced is owned by Nucain Ltd. The developer holds no rights. An NDA and IP assignment agreement must be signed before full project details are shared. Dummy data only during build, no real end-user data at any stage. Looking for one serious, experienced developer. Quality over speed….
