About

Backend Software Engineer with 4+ years of experience building scalable backend systems across fintech, mobility, and IoT. I primarily work with Golang and enjoy building reliable backend services, event-driven systems, and APIs that power real-world products. Over the last few years, I've worked across Golang, Java (Spring Boot), and Ruby on Rails, with hands-on experience in Kafka, PostgreSQL, Redis, Docker, Kubernetes, and cloud-native infrastructure. At Zoomcar, I've built and owned backend features that reduced host cancellations from 18% to ~11% and from ~11% to ~4% for eligible hosts, contributing to an estimated ₹5L monthly GBV uplift. I've also worked on production-critical systems including ratings, reviews, IoT backend services, observability with OpenTelemetry, and distributed event processing. Previously at PaywithRing (Kissht), I built reusable onboarding platforms and event-driven backend services that reduced financier onboarding time from months to under three weeks. At Simpl, I worked on the Billbox platform, building payment features, improving transaction reliability, and developing internal tools for finance operations. I enjoy solving production problems just as much as building new features—whether it's debugging distributed systems, improving reliability, or designing clean backend architectures. Outside work, I'm an active competitive programmer: • LeetCode Guardian (Max Rating: 2178) • Codeforces Expert (Max Rating: 1632) • CodeChef 5-Star (Max Rating: 2022) • Global Rank 46 – CodeChef Div 2 • Facebook Hacker Cup Round 2 Qualifier I'm currently open to Backend Software Engineer / SDE-2 opportunities, especially in teams working on distributed systems, platform engineering, cloud infrastructure, and high-scale backend services.
