About Me

I'm a backend engineer. I work primarily with Node.js, Express.js, and databases (MongoDB/PostgreSQL), building APIs, services, and developer tools that are fast, reliable, and easy to maintain.

I care about clean abstractions, well-structured schemas, and APIs that stay stable across versions. I think about data flow, error handling, and WebSocket synchronization.

When debugging, I trace request flows and query optimization before touching code. I value code that is explicit, robust, and testable, and I love building real-time integrations.
