About

Backend-first engineer. I like problems that have data, rules, and consequences.

I work on data-heavy internal platforms where correctness matters: allocations, reporting, monthly workflows and production support. My day-to-day is a mix of backend development, query optimization, incident resolution, and automation.

I care about maintainability: structured logging, validation, safe refactors, and predictable behavior under real-world constraints.
