I’m a backend platform engineer with 6+ years of owning distributed systems and event-driven pipelines in production. My focus is on building data-intensive backend services that stay resilient under real traffic pressure.

At 99.co, I architected the canonical property data platform consolidating feeds from 5+ sources into a single dataset. I cut event processing latency from 2 hours to under 3 minutes and supported 100K+ active listings, while eliminating data inconsistencies that caused ~15% of listings to surface with stale or conflicting attributes.

At Blinkit, I owned real-time inventory pipelines sustaining 10K+ events/minute across 200+ dark stores during peak-demand surges. I built Kafka consumer topology for in-order processing per store, and fixed silent failure modes by adding exponential back-off with dead-letter routing—reducing inventory-inconsistency incidents by ~60%.

I’m deeply hands-on with Kafka internals, JVM tuning, and GCP infrastructure, and I reduce on-call toil through observability-first design and resilience engineering. I also optimize cost on GCP (e.g., spot instances + autoscaling to maintain 99.9% uptime) and mentor engineers on distributed systems design patterns.
