I like building things with code. Most recently that has meant using large language models (LLMs) and agentic AI to allow for autonomous robot decision-making at the Johns Hopkins Applied Physics Laboratory.

Other than coding, I watch animeNow watching: The Apothecary Diaries and play a lot of Nintendo Switch Sports (tennis, mostly).
