What I'm looking for

I seek a role building scalable backend and platform systems with strong observability and CI/CD, collaborative teams, and opportunities to mentor and lead technical design.

I am a senior full stack software engineer with 10+ years designing and delivering highly scalable backend systems, distributed crawlers, and data processing pipelines for high-throughput production environments. I build low-latency APIs and multithreaded ingestion workers using Go, C/C++, Java, Spring Boot and drive observability, CI/CD, and Kubernetes practices to maintain reliable services supporting millions of monthly users.

I have a proven track record reducing latency, increasing throughput, and improving reliability—examples include a 37% API latency reduction, a 4x increase in crawler throughput, and raising test coverage to 92% for core services. I mentor engineers, author architecture and runbooks, lead incident response, and continuously optimize systems for performance and maintainability.
