I build AI-powered SaaS products, full-stack applications, and scalable backend systems that ship to production. PROOF FROM SHIPPED WORK • Helped a client’s product reach $10K+ MRR by building the core application they run on • Built a web application serving 800+ active users with high monthly transaction volume • 100% Job Success Score on Upwork (Top Rated) WHAT I CAN HELP YOU WITH • AI SaaS Development: AI-powered products, LLM integrations, AI agents, workflow automation, OpenAI API, Claude API • Ruby on Rails: SaaS development, API integrations, performance optimization, legacy app maintenance • Full-Stack Development: MVPs, dashboards, marketplaces, web applications (React, Next.js, Node.js) • Backend Engineering: REST APIs, database design, background jobs, third-party integrations HOW I WORK I turn messy requirements into a working version fast, then harden the failure cases — partial API failures, bad model output, stuck jobs, and webhooks that drop. You get clear daily progress and production-ready code.
