Turning ideas into engaging mobile development products delivered at scale

(About Me)

Clean

code.

I build mobile experiences that scale — from sleek MVPs to apps serving over a million users. I started coding when I was 14, driven by curiosity and a love for turning ideas into something real. Over the years, I evolved from native Android development to mastering React Native, publishing 20+ apps on both the App Store and Google Play. Whether solo or leading a team of eight, I take products from concept to production with attention to detail and a passion for performance.

With a global perspective shaped by traveling to over 80 countries, I bring adaptability, clarity, and empathy to every project. My work has been featured in IEEE publications, and I approach every app not just as a piece of software, but as a user experience that should feel intuitive, delightful, and reliable. If you're looking for someone who can think like a developer, a product owner, and a user — let’s build something together.
