Summary

I am looking for a strong full-stack developer to help take an existing AI-enabled SaaS prototype into MVP. The prototype is already built and the product workflow is mapped. I now need someone who can help translate that into a real product with clean architecture, sensible MVP scope, and strong technical judgement. What I need I need someone who can: * review the existing prototype * recommend the right MVP structure * build the first functional version properly * make good decisions about what belongs in MVP vs later phases * work clearly with a non-technical founder Core skills required Please only apply if you are confident with most of the following: * Frontend: Next.js, React, TypeScript, Tailwind CSS * Backend: Node.js / full-stack JavaScript or TypeScript * Database: Supabase, PostgreSQL, Firebase, or similar * Authentication: NextAuth/Auth.js, Clerk, Supabase Auth, or similar * Deployment: Vercel * Version control: GitHub * Product build: taking a prototype or design into a structured MVP * Workflow logic: building multi-step user journeys and connected dashboard-style products * Clean architecture: scalable code structure, sensible component organisation, reusable logic * API / AI integration readiness: experience preparing products for future AI/API workflows * Communication: ability to explain technical decisions clearly to a non-technical founder Nice to have * experience with SaaS dashboards or workflow tools * experience with EdTech, productivity, or HR / professional development platforms * experience integrating AI features or preparing products for AI-supported workflows * experience with Figma handoff / design-to-build implementation This is a good fit if you have * built SaaS products from prototype to MVP before * strong frontend and backend experience * good product sense, not just coding ability * the ability to think practically about scope, speed, and future scalability In your proposal, please include * 2–3 relevant SaaS / MVP examples * whether you have taken a product from prototype to MVP before * the tech stack you would recommend for this build * how you would approach scoping Phase 1 of the MVP * your pricing approach and likely budget range * your availability and estimated timeline Process I would expect to start with a prototype review and a clear MVP recommendation before development begins. At this stage, I am sharing enough to recruit the right person. More detailed product information will be shared with shortlisted candidates.
