I build things — mostly machine learning, systems, and online software.

I like understanding the whole pipeline, not just the API on top. Lately that's machine learning and AI — training models from scratch, fine-tuning, and the tooling around them. I also build online software, and wander into game engines, reinforcement learning, and graphics when an idea demands it.
