About

👋 I’m a Backend + Fullstack Engineer (SDE-II) building scalable, reliable systems across IoT, healthcare, and fintech. 💡 I focus on distributed systems, event-driven design, and cloud-native infra — writing code that’s not just functional, but resilient, performant, and production-ready. 🚀 Key wins so far: 📦 Rebuilt a CRM monolith → 5+ microservices (Kafka+ PostgreSQL + Redis), cutting failures by 80% and reducing onboarding from 5 days → 2. 🏠 Scaled a Smart Home IoT backend to 100K+ devices & 10K RPS, with CRDT-based sync + OTA firmware updates. 📊 Built an observability pipeline (Kafka + ClickHouse) for 1M+ logs/day, reducing MTTR by 65%. ⚡ Side projects: tested a video streaming system for 500K+ concurrent users and a trading engine benchmarking 100K trades/day. 🧰 Tech I use daily: TypeScript, Node.js, NestJS, Go, PostgreSQL, Redis, Kafka, Docker, Kubernetes, AWS. ✅ Along the way, I’ve written design docs, contributed to CI/CD + DevOps standards, mentored juniors, and collaborated with cross-border teams. 👉 Currently at Lloyds Banking Group (contract), working on real-time banking integrations. Open to global opportunities (UK/EU) where I can keep scaling systems and growing as an engineer.
