You will get Fullstack Developer SaaS Developer | Next.js, React & Node.js
Project details
I build production AI/SaaS applications with Next.js + Supabase + OpenAI that deliver measurable business outcomes. My specialty is turning complex requirements—document Q&A, financial automation, travel policy engines—into scalable, secure web apps in weeks, not months. I combine a 5-step process (Discover, Architect POC, Build in Sprints, Deploy, Handover) with a modern stack to ensure 40% faster launches and 30% lower costs. Clients get full-stack expertise, real-time features, enterprise-grade security (RLS, SOC 2), and clear ROI tracking. Let’s build your MVP or scale your platform with a stack that grows with you.
