Senior Software Development Engineer @Swiggy — Distributed Systems & Payments Infrastructure | Kafka · Go · Java · AWS · Microservices | Ex-Flipkart/Myntra, CarWale, Amazon | 8+ yrs | 100K+ TPS, 98% reliability

About

I build the payment infrastructure that isn't allowed to fail — the retries, idempotency checks, fraud validations, and rollback logic that move money for millions of users without anyone noticing they exist. Over 8+ years across Swiggy, Flipkart/Myntra, and CarWale, I've gone from writing my first production service to architecting payment gateway integrations, wallet migrations, and refund systems processing 100K+ transactions a day at sub-500ms p99 latency. I work primarily in Go, Java, and event-driven, distributed architectures (Kafka, gRPC, Redis), and I'm equally comfortable designing a system on a whiteboard and debugging it in production at 2am. and I care about the craft: clean interfaces, observable systems, and infrastructure that the next engineer can actually understand. What I've built and shipped: Took payment refund success rates from 70% → 98% by redesigning retry, idempotency, and circuit-breaker logic — cutting manual ops effort by 85% Migrated 2M+ users onto a new wallet system with zero fund loss and a full rollback safety net Led integration of 8+ payment gateways handling 100K+ daily transactions Cut CI pipeline time roughly in half and took automated test coverage from 45% → 85% Mentor engineers on system design, payments architecture, and production readiness What I work on: → Payment gateway integrations (10+ gateways across two companies) → High-throughput distributed systems in Go and Java → Resilience engineering — retry, circuit breakers, DLQs, fallbacks → Event-driven architectures using Kafka and gRPC → Platform reliability — SLA dashboards, p99 latency, observability I'm looking for senior/lead engineering roles — ideally in fintech, marketplaces, or infrastructure — where I can keep building resilient, high-scale systems and help other engineers get better at doing the same. Open to remote opportunities. Tech: Go · Java · Kafka · gRPC · Redis · DynamoDB · MySQL · AWS · Kubernetes · Spring Boot · Prometheus · Grafana
