ABOUT

Get to know me better

I build scalable systems with a martial artist's discipline.

I'm a Full Stack Developer who transforms complex business problems into elegant, efficient, and scalable web solutions. Using modern JavaScript frameworks and cloud technologies, I focus on clean code, robust architecture, and delivering end-to-end products that truly perform under pressure.

My approach to software engineering is deeply rooted in my lifelong dedication to sports. I've spent the last 13 years training Taekwon-do (holding a black belt) and the past 4 years mentoring and coaching kids as an instructor. Teaching martial arts has honed my patience, communication, and ability to break down complex concepts—skills I use every day when designing databases, planning system architecture, or communicating with clients.

When I'm not writing code or on the mat, I explore the latest video games in search of fresh UI/UX inspiration.
