About me
I'm a full stack developer specializing in SaaS platforms, AI-powered
web applications, and trading/fintech dashboards. I build end-to-end
products using React (TypeScript), FastAPI, PostgreSQL, and Supabase.
I've shipped production-grade SaaS projects, including a live trading
signal platform with multi-strategy analysis and institutional-grade UX.
I care deeply about clean architecture, performance, and delivering
products that actually work at scale.
If you need a developer who thinks like a founder and ships like an
engineer, let's talk.
