What I'm looking for

I’m looking to build reliable, high-availability systems where I can optimize performance and latency using Java, distributed architectures, and cloud infrastructure—partnering across backend and frontend to deliver real-world outcomes.

I’m a Senior Software Engineer with extensive experience building scalable, high-performance systems. At PagerDuty, I built backend alert-processing services with Java, SpringBoot, and PostgreSQL, supporting incident routing, escalation workflows, and real-time operational event handling in a high-availability platform.

I also modernized backend APIs and service communication patterns to reduce latency for high-volume operational dashboards, and I improved platform stability using AWS, Docker, Kubernetes, and CI/CD pipelines. Earlier, as a Frontend Developer at Uber, I shipped rider-facing web applications with real-time status updates, boosting engagement and reliability across global regions.
