Profile

Backend and full-stack engineer with 5+ years building fintech, SaaS, and AI products in production. 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 WaaS), Refactor AI (LLM-powered code audit tool), and PicConvert (image SaaS with published Figma + Framer plugins, 30+ users). I work best with teams that need someone who can own a system end-to-end — architecture, delivery, and everything in between.
