About

I'm a Backend Developer with hands on production experience building and securing web applications that scale. My work lives at the intersection of clean architecture, security, and performance.

At TechRitzy, I engineered 40+ RESTful APIs capable of handling 10K+ concurrent requests, implementing layered authentication systems (JWT, MFA via TOTP, OAuth 2.0) and slashing response times by 40% through Redis caching strategies.

I thrive in product driven teams where backend decisions directly shape user experience. Whether it's designing normalized database schemas, building real time WebSocket tools, or architecting microservices from scratch, I bring both depth and care to the work.
