About

Senior Backend Engineer with 6 years building high-throughput distributed systems in Java/Spring Boot at consumer-scale companies (Narvar, Swiggy, OLX). At Narvar, I am a core member of the Messaging team — 14 microservices powering the company's highest-revenue vertical, processing ~10M messages/day at 35K req/sec peak for 1,400+ global retailers. Before that, I owned Swiggy's Ads Serving Layer (55K RPM across Food and Instamart) and built the Fleet Manager platform backend serving 300K delivery executives. What I'm deep in: • Event-driven architecture — Kafka, AWS SQS/SNS, async pipelines at scale • Microservices and system design — P0 services with 99.9% uptime under peak load • Data stores — MySQL, DynamoDB, Redis, PostgreSQL • AI-assisted engineering — early adopter of Claude Code and Cursor for production delivery, not just prototyping I care about owning systems end-to-end: design, build, ship, operate, and be on-call for what I write. 📧 siddhant.nagelia@gmail.com
