Full-Stack Developer

I build software across the full spectrum — production APIs, native mobile apps, and immersive games. Engineering quality and design craft, not either/or.

Building across
the whole stack.

I'm a software developer who builds things end to end — from production backend APIs to native mobile apps to 3D game worlds. Not because I'm trying to do everything, but because I genuinely find all of it interesting.

I care equally about engineering quality and user experience. A well-architected system that's painful to use is only halfway done. I think about both sides — the code structure and the person sitting in front of it.

My work spans real-time collaboration platforms, mobile social apps, and systems-driven game design. Each domain teaches something the others don't.
