Full-Stack & AI EngineerBuilt. Deployed. Scaled.From zero to production.
I've built, shipped, and scaled full-stack applications end to end, including a product I personally coded and delivered that has crossed $100k ARR and is actively used by real customers.
I'm a Full Stack Engineer who owns problems from database design to frontend UX to production reliability. My work isn't theoretical, it lives in production, handles real traffic, integrates with third-party systems, and breaks if the fundamentals aren't right.
