IndiaWhat I'm looking for
I’m a Backend Engineer focused on distributed systems and backend infrastructure, with 7+ years of experience building and operating large-scale platforms. I’ve owned end-to-end architecture and led cross-team reliability initiatives across Microsoft, JPMorgan, and Samsung.
At Microsoft, I led a prioritization platform for SharePoint crawler processing at 10B+ requests/day, cutting critical workload completion time by 60% (P95 10 min → 4 min). I also reduced Copilot-enabled search P95 API latency by 50% by eliminating lock contention and optimizing parsing workflows.
Across my work, I’ve driven measurable reliability and efficiency outcomes—99.95% uptime, 50% P95 latency improvements, and 35% compute cost savings—while mentoring 5+ engineers, running 100+ code reviews, and resolving high-severity production incidents through root cause analysis.
