I build AI-powered SaaS products for startups, and they actually ship. On time, production-ready, the kind of code you won't be paying someone to rewrite in three months. Twelve MVPs out the door so far, three of them earning revenue inside 90 days. Top Rated, 100% Job Success Score. We're probably a fit if you've caught yourself thinking: "We needed an MVP yesterday, but it has to be built right, not throwaway code." "We want AI features and our last dev had no idea where to start." "Our previous developer ghosted us, shipped spaghetti, or blew every deadline." What I build: - AI-powered SaaS platforms, from concept to a deployed product people pay for - LLM features like intelligent search, chatbots, document processing, and knowledge assistants - Custom RAG pipelines that connect your data to GPT-4, Claude, or open-source models - AI agent systems with tool use, MCP integrations, and multi-model routing - Full-stack web apps with clean UIs, backends that scale, and automated workflows - API and workflow integrations: Stripe, Twilio, n8n, custom webhooks My stack is Next.js, React, Python, FastAPI, Supabase, the Vercel AI SDK, LangGraph, and pgvector. I pick what fits your product instead of padding the list to look impressive. Founders come back for project #2, #3, and #4 because I don't just write code. I think about the product itself: which architecture calls actually matter, where the UX tradeoffs hide, what to build now and what can wait. One client put it this way: "You're the first developer who actually understood what we were trying to build before I finished explaining it." That's what I'm aiming for every time. I'm not your guy if you want the cheapest dev on the platform, or you need WordPress maintenance and basic landing pages, or you're still figuring out what to build. (Though if it's that last one, I'm happy to talk it through on a quick call.) I work best with founders who move fast, say what they mean, and want a real technical partner, not someone to hand tickets to. Send me your project details and I'll get back to you within a few hours.
