Senior Backend Engineer with 8 years building Node.js/NestJS APIs and event-driven microservices for fintech, logistics, IoT and SaaS platforms serving 10,000+ users. I build REST/GraphQL APIs, design RabbitMQ/Kafka pipelines, integrate Stripe/Razorpay (idempotent, webhook-reconciled, zero duplicate charges), harden auth with JWT/OAuth2, and set up CI/CD, Docker/Kubernetes deployments. Track record: cut API latency 25-40% across four systems, raised auth throughput 5x. I work in remote, cross-timezone teams using Claude Code/Cursor to move fast without cutting review quality.
