Passionate engineer.
Precision-driven builder.

I'm a Senior Software Engineer with over a decade of hands-on experience designing and delivering cross-platform mobile and web applications. From early-stage Android apps in Java to modern React Native products live on the App Store and Play Store, I've built solutions that scale.

My passion lies at the intersection of clean architecture and exceptional user experience. I thrive in fast-paced environments, collaborating across frontend and backend to ship end-to-end features that users love. Whether it's a real-time geolocation system, a fintech mobile app, or an AI-powered platform โ€” I bring precision, creativity, and deep technical expertise to every project.
