About Me

I'm a full-stack engineer and founder of Airflute Technologies, building production products across EdTech and SaaS for 5+ years.

I own products end-to-end — from architecture and implementation to release and iteration with users. My work includes exam platforms serving 500K+ learners, AI-powered OCR pipelines, and real-time quiz delivery systems.

I'm known for translating ambiguous product requirements into reliable, measurable outcomes — shipping across Next.js, Flutter, TypeScript, Supabase, and Firebase.
