Twelve years making backend systems fast, reliable, and safe to change as they grow. I work on the core that thousands of teams depend on without ever thinking about it.
Performance and reliability are not features you add later. They are decisions you make early — in the data model, the query, the boundary between services.
My throughline is the unglamorous core: query performance, data modeling, and clean service boundaries inside large, mature applications. The work that never shows up in a screenshot but decides whether a product feels instant or sluggish, stable or fragile.
I care about making systems safe to change. A codebase that thousands of engineers can move quickly in — without fear — is the real deliverable.
Query optimization, read models, caching, and search. Led a SQL → Elasticsearch migration for proximity search on a large marketplace.
Service boundaries, data modeling, and resilient delivery — keeping large systems coherent as teams and traffic grow.
From psychometric modeling to LLM evaluation — making generative tools dependable enough to ship in production.
