I’m a Senior Site Reliability Engineer with 11+ years of experience in large-scale distributed systems, focused on incident response, reliability engineering, and system-level troubleshooting. I lead high-severity incident management, perform deep root cause analysis (RCA), and drive long-term improvements that prevent recurring failures.

I design observability strategies, define SLOs, and use logs, metrics, and system-level diagnostics to improve system resilience in mission-critical production environments. I’ve worked across Linux-based infrastructure and multi-node cluster architectures, diagnosing issues like memory corruption, I/O bottlenecks, and inter-node communication problems.

I also automate operational workflows using Python and Bash to increase incident response efficiency and reliability. From proactive monitoring to post-incident prevention and long-term fixes, I build stability through structured RCA and continuous platform health improvements.
