Profile

Product Engineer with 5+ years turning ideas into reliable, revenue-generating fintech, SaaS, and AI products in production. I own systems end-to-end — architecture, backend, frontend, payments, and infrastructure. I maintain Nextpayday (18,000+ borrowers) and Billp (300+ users), both on infrastructure I built and manage myself. Beyond client work, I ship my own products: Presency (multi-tenant commerce platform, live with 50+ paying businesses), Refactor AI (LLM-powered code audit tool), and PicConvert (image SaaS with published Figma + Framer plugins). I work best with founders and small teams who need someone to own a system from idea to live product.
