🧑‍💻 SDE-3 with experience across a fast-growing product startup and an established edtech platform serving millions. I build, own and operate backend systems end to end. 🎮 Currently the sole backend owner of a production multiplayer learning platform: Socket.IO game-state sync, ELO matchmaking, Elasticsearch over 12M records, BullMQ workers, and Prometheus/Grafana observability across all services. 💬 Built and scaled a WhatsApp Business API automation platform as the only backend engineer: 1M+ campaign messages/quarter, ~100K messages/day/bot, 99.9% uptime. ⚙️ Core stack: Node.js, TypeScript, NestJS, PostgreSQL, Redis, Kafka, RabbitMQ, BullMQ, Elasticsearch, Docker, GitHub Actions 📐 I write the design doc and build a POC before committing to a full build. I work directly with clients on scope and trade-offs. 📊 Measurable outcomes: 40% lower search latency, 35% faster API responses, 50% faster incident detection, 10x business reach expansion. 🤝 Book a session for: backend architecture decisions, NestJS/Node.js debugging, PostgreSQL schema and migration strategy, event-driven system design, resume reviews for SDE-2/SDE-3 roles, or mock interviews. 📍 Delhi, IN · English and Hindi
