Backend engineer focused on turning slow or unreliable backend flows into faster, more maintainable systems. I work across Node.js, PostgreSQL, ClickHouse, and Snowflake, with a focus on backend performance, data systems, and thoughtful system design.
At Chartmetric, I worked on music-analytics backend systems — reducing latency from minutes to seconds, improving reliability on user-facing endpoints, and contributing to infrastructure savings through migration and cleanup.
