motto: "From the math behind it, to the system that runs it."I work at the boundary between theory and engineering — implementing models from research, designing language interpreters, simulating real systems, and shipping full-stack applications end to end. I also grind problems on Codeforces to keep my algorithmic edge sharp.
What I'm doing right now
- Shipping features on PermitCycle — a production engineering platform for U.S. permit workflows.
- Researching Information Retrieval (LSI, BM25, RAG) on the ShealtRI Health/Medicine search engine.
- Improving my Codeforces rating with daily problem solving.
- Exploring game-tree search (MCTS / PUCT) for adversarial games.
