🚀 About Me

Software Engineer with 3+ years designing scalable backend systems at production scale. Currently at Juspay building NammaYatri — India's largest open-source mobility platform serving 200K+ rides/day and processing 5M+ daily transactions. I own core backend systems where every millisecond of latency and every dollar of infra cost is a design decision.

My work spans the full backend depth: Redis/Valkey KV infrastructure at 5K+ events/sec, multi-cloud routing with zero-downtime deployments, autonomous SRE agents, and CPU profiling in Haskell. I care about systems that are observable, cost-efficient, and stay up at 99.9% availability when traffic spikes unexpectedly.

Latency Cost Uptime Scale

  • 📍 Based in: Bangalore, India
  • 🎓 Education: B.Tech in Information Technology | KNIT Sultanpur (2018–2022) | 8.5 CGPA (Top 5%)
  • 🏆 400+ problems solved on LeetCode & CodeChef
  • ⚡ Fun Fact: I architect distributed systems better with a cup of chai in hand!
