Senior fullstack engineer specializing in MERN microservices, event-driven systems, and performance optimization.
IndiaWhat I'm looking for
I’m a Senior Fullstack Engineer with 7+ years designing and scaling high-performance web applications on the MERN stack. I lead end-to-end delivery, translating product needs into robust frontend and backend solutions with a strong focus on system design and reliability.
In my recent role at Undocked, I directed fullstack development for enterprise and logistics platforms, building scalable React/TypeScript applications with Material UI and Tailwind CSS. I developed and optimized REST and GraphQL APIs using Node.js, Express.js, and NestJS, and improved performance by reducing page load times by up to 50% through MongoDB query and API optimization.
I’m especially strong in event-driven architectures—using AWS SQS and Kafka—along with building reusable UI foundations (20+ components) and production-grade features like role-based access control, admin dashboards, and localization (i18n). Earlier, at Quess Corp, I built backend services for healthcare integrations with Node.js/Express, wrote unit tests, and resolved critical production issues to improve system reliability.
