I build and stabilize AI automation, agents, and full stack SaaS products that need to work reliably in production, not just in demos. I’ve shipped and scaled systems for founders from Y Combinator, Founders Factory, FutureLabs, and Republic of Work. Founders I’ve built with have gone on to raise €2M+, and my AWS/serverless work ranks in the top 0.2% for DevOps. A few results: ⚡ Multi-tenant SaaS with 28% faster integrations ⚡ Serverless system running under 200ms latency at 10K+ users ⚡ AI RAG system improving support efficiency by 45% ⚡ Next.js migration reducing hosting costs by 15% ⚡ SaaS MVPs shipped to production, with founders raising after launch A lot of products today get built quickly with Cursor, Lovable, Bolt, Claude Code, or an early freelance team. Then real users arrive. That’s when the problems show up: messy code, fragile backends, AI features that worked in the demo but fail in production, scaling bottlenecks, unreliable automations, and rising AWS costs. I help turn that into a production-ready system with clean architecture, a solid backend, reliable AI behavior, and room to scale. I also build new products properly from idea to MVP to production. What I can help with: * AI agents, chatbots, and AI voice agents * Workflow automation and business process automation using n8n, Make, Zapier, and APIs * Production RAG, LLM, and knowledge-based systems * Full-stack SaaS development with Next.js, React, Node.js, TypeScript, JavaScript, and Python * Backend systems, REST APIs, third-party integrations, and multi-tenant architecture * PostgreSQL, Supabase, Stripe, AWS, serverless, performance, and cost optimization * Stabilizing fragile or AI-built MVPs before they become technical debt How I work: We can start small. Send me your app URL, repo, or brief with a short note on the problem. I’ll review the likely bottlenecks, scaling risks, reliability issues, and what I would fix first before you commit to anything bigger. From there, I can take technical ownership of the build: architecture, backend, integrations, AI systems, delivery, and the parts that usually stall. I work best with: * Funded startups starting with or moving beyond MVP * SaaS teams hitting scaling, reliability, or cost issues * Founders who want a senior engineer to take ownership, not just ship tickets I’m probably not the right fit if you’re looking for the cheapest possible build. I’m a fit when the product matters, users depend on it, and it has to work. Tech I work with often: Python, JavaScript, TypeScript, React, Next.js, Node.js, AWS, Supabase, PostgreSQL, Stripe, serverless, OpenAI, Claude, Gemini, RAG, LangChain, AI agents, n8n, Make, Zapier, automation, and APIs. If your product was built fast and now needs to work properly, or you want it built right from the start, send me the repo, app, or brief, and I’ll tell you what I’d fix first.
