Lead full-stack engineer specializing in cloud-native microservices and micro-frontends for high-scale apps.
IndiaWhat I'm looking for
I’m a Lead Full‑Stack Engineer with 9+ years of experience designing and building cloud‑native, scalable, and high‑performance web and mobile applications, with equal depth across frontend and backend. I’ve owned systems end‑to‑end—from architecture and system design to scalable UI, backend services, CI/CD, observability, and production reliability, often handling millions of requests per day and 1M+ records.
In recent roles, I architected microservices and BFF layers (Node.js/NestJS, GraphQL/REST) for high‑traffic systems, reducing cloud costs ~60% by optimizing Cosmos DB (Gremlin), redesigning data models, and introducing Redis caching, while improving p95 latency and throughput. I’ve built scalable frontend foundations (React, Next.js), established CI/CD pipelines and automated testing (Jest), and improved production quality with code quality gates (SonarQube, ESLint), while leading system design reviews and mentoring 10+ engineers. Across my career, I’ve modernized legacy stacks into React micro‑frontends (Module Federation), reduced bundles 70–80% and improved Core Web Vitals, and built internal full‑stack tooling to cut dev/ops effort 70–80%, with a consistent focus on performance optimization, API security, and engineering standards.
