Profile

identity verified

Seven years of building scalable, high-throughput systems as a backend engineer. My day-to-day lives in REST APIs, database performance, and backend automation across both monolithic and microservices architectures.

I lean toward clean, maintainable code and measurable outcomes — shaving turnaround times, cutting manual ops, and shipping infrastructure that scales quietly. I work the full stack of the back end: design, query plans, queues, deploys, observability.
