About

Backend Engineer with 5+ years of experience building high-scale fintech systems that actually move money reliably, at speed, and at scale. At Lendbox, I own backend infrastructure serving 1.5M+ borrowers, processing Rs. 5Cr+ in daily transactions, and delivering 100K+ notifications/month across email, WhatsApp, and SMS. I've led projects end-to-end from refactoring a monolith into 6+ TypeScript microservices, to engineering an AWS event-driven webhook system with 99.99% uptime, to correcting 700,000+ loan records with zero downtime. My stack: Node.js · TypeScript · AWS (SNS, SQS, Step Functions) · Redis · MongoDB · MySQL · Docker · Microservices Previously at Accenture, I built financial modules handling high-throughput traffic with sub-100ms response times and 99.9%+ uptime. I thrive in environments where backend decisions have real business consequences and I take full ownership of what I build.
