About
I build systems that scale, lead teams that ship, and solve problems others avoid. Always open to bold ideas and to connecting with people who want to build the future.
I've been building for as long as I can remember. As a kid, it was elaborate LEGO castles—the kind that took over entire rooms and drove my parents crazy. Later, it was tearing apart electronics to understand how they worked, much to their continued frustration. Today, at 24, it's architecting firmware for 10,000+ production devices. The medium evolved from plastic bricks to code and circuits, but the fundamental drive never changed: I see a problem, and I need to solve it. That relentless drive was shaped in the pool. I was a competitive swimmer for over 12 years—20+ hours a week, early mornings before school, racing at regional and national levels. Swimming taught me something that stuck: raw talent means nothing without discipline. The athletes who won weren't always the most gifted; they were the ones who showed up every single day, even when it hurt. Swimming also taught me that goals without plans are just dreams. You don't shave seconds off your time by wishing—you build a training plan, execute it relentlessly, and measure every stroke. That mindset carries through everything I do now: clear targets, disciplined execution, constant iteration. Whether it's a training block or a product roadmap, the formula is the same. Technology is the most powerful lever humanity has ever created—the one thing that can genuinely scale positive change, touching millions of lives and solving problems that once seemed permanent. That's why I build. I'm not interested in building for the sake of building. I want to contribute to something larger—work that combines ambitious vision with disciplined execution. The world has enough incremental improvements. What excites me is the intersection of deep technical challenge and genuine human impact. At 24, I'm looking for my next big swing. The kind of challenge that seems impossible to most people. I'm drawn to teams that ship, founders who execute, and problems that actually matter. Not looking for safe—looking for meaningful. Ambitious opportunities where technical depth meets real-world impact.
