About me
I build AI-powered web apps and automation systems that actually work in production.
9+ apps shipped across SaaS, fintech, and e-commerce. Real results: 99.86% ML accuracy, 98+ Lighthouse scores, 100% OWASP security .
What I build:
→ AI automation workflows (n8n, Make, Zapier + custom agents)
→ Full stack SaaS apps (Next.js, Supabase, OpenAI API)
→ Vibe-coded app rescue (Lovable, Cursor, Bolt — fixed fast)
→ API integrations (Stripe, auth, third-party services)
I ship clean, production-grade code not prototypes. Message me with your problem and I'll tell you exactly how to solve it.
