Project details
You will get a production-ready AI platform MVP, built to validate your idea, impress investors, and onboard real users fast. Whether you need an AI chat assistant, image or content generation, semantic search, or an AI-powered marketplace, I turn your concept into a working, scalable product, not just a prototype.
I specialize exclusively in AI-powered MVPs, combining modern full-stack development (Next.js, Node/Python, Postgres, etc) with the latest LLM and AI integrations (OpenAI, Anthropic, RAG, vector search...). You get clean, documented code, a responsive interface, and full ownership of everything I build.
My focus is simple: ship a real product that works, in weeks not months, so you can launch, learn, and grow. Let's build something users love.
