I obsess over making things fast. Query plans, memory layouts, execution paths, cache behavior — I want to understand why something is slow and fix it at the root.

I work where systems performance, machine learning, and environmental data intersect — where shaving milliseconds off a query and predicting groundwater recharge are the same kind of thinking.
