Software Engineer

I’m a full-stack developer and frontend lead who enjoys building thoughtful, well-crafted products. I care about clean systems, clear communication, and the space where technology meets human experience.

Outside of work, I’m driven by curiosity, whether that’s diving into music, film, psychology, or any idea that feels worth exploring. I believe the best products come from people who stay curious and never stop refining both their craft and themselves.
