I'm a full stack developer with 7+ years building AI-powered SaaS platforms and web applications with Next.js and React. I help startups and product teams ship the whole product — not just a frontend — so founders go from idea to first paying users without stitching five contractors together. Over the last 7 years I've delivered 28+ web application and SaaS projects, including 10 AI-powered products with LLM integration (OpenAI, Claude, and Gemini APIs). A recent AI SaaS build cut client onboarding time by 90% and handled Thousands of active users on launch. On another web application, I improved page load speed by90% and reduced infrastructure cost by 70% by moving to the Next.js App Router with Server Components. What I build as a full stack developer: AI-powered SaaS platforms and MVPs with Next.js, React, and TypeScript — end to end AI integration and AI chatbot features: LLM APIs, RAG pipelines, and vector search over your own data Multi-tenant SaaS architecture, authentication, billing, and admin dashboards Web application development: REST APIs, PostgreSQL/Supabase, and serverless deployment on Vercel and AWS Angular web application development and AngularJS-to-Angular migrations for enterprise dashboards My core stack: Next.js, React.js, TypeScript, Node.js, AI integration (OpenAI API), RAG, PostgreSQL, Supabase, REST API, Tailwind CSS, and Angular. I've shipped 30+ SaaS platforms and 20+ AI chatbot integrations, and I own the full build — architecture, frontend, backend, and deployment. How I work: clear scope on the first milestone, progress updates every 5 days, and clean, maintainable code you can hand to any team later. Most clients start with a small paid milestone, then move to a long-term engagement. If you need a Next.js or React developer to build an AI-powered SaaS platform or web application from scratch — or to add AI integration to an existing app — send me a message with what you're building and I'll tell you exactly how I'd scope it.
