About

I’m a Software Development Engineer at Ola-Krutrim, focused on architecting resilient, high-throughput backend systems that power cloud-native infrastructure. I spend most of my time at the intersection of distributed metering and billing, event-driven pipelines, and production reliability. Whether it's diagnosing memory behavior under load, optimizing database queries, or designing disaster-recovery strategies, I enjoy solving complex problems at scale. What I’m working on right now: 🔹 Microservices in Go: Architecting production-grade Balance and Invoice services. 🔹 High-Performance Caching: Fine-tuning API latency and data consistency using Redis. 🔹 Metering Architecture: Building event-driven pipelines with Kafka Connect and OpenMeter. 🔹 Resilience & DR: Implementing shard-aware backup and recovery workflows for ClickHouse clusters. 🔹 AI for Ops: Experimenting with AI agents to automate operational toil and streamline on-call workflows. Core Tech: Go | Kafka | Redis | PostgreSQL | ClickHouse | Docker | Kubernetes ✍️ I write about technical deep-dives like ClickHouse backups, Kafka reliability, and Go OOM troubleshooting. 📍 Bengaluru, India | 🎓 B.Tech in CSE, NIT Patna ('25)
