I’m a senior full-stack software engineer with deep expertise in Node.js and its event-driven architecture, building robust and scalable backend systems. I develop and maintain applications using Node.js, MongoDB, Express.js, and NestJS, with a focus on efficiency and responsiveness. I design efficient data models and queries to handle large volumes of data, and I build RESTful APIs with routing and middleware.

I’ve developed and maintained the backend infrastructure for the digital mall platform using Node.js on AWS. I integrated Socket.io for real-time communication, Firebase Push Notification for chat, updates, and notifications, and implemented Firebase Authentication for secure authentication and authorization. I also used Stripe and Plaid for secure payment and financial data flows, and deployed and managed the application using Microsoft Azure cloud services (including Azure Blob Storage) for reliable file storage and retrieval.

Previously, I worked as a MERN Stack Developer building both backend and frontend components with Node.js and React.js. I integrated Stripe and Plaid for seamless payment processing, used Socket.io for instant updates, notifications, and chat, and worked on SQL database solutions for structured data, caching strategies, and query performance improvements. I collaborated closely with frontend teams to design RESTful APIs and ensure smooth client-server data flow.

I’ve also built MERN stack applications with MongoDB, Express.js, React.js, and Node.js, including Next.js work for server-side rendered (SSR) and static generated React.js experiences. I’ve integrated Google APIs such as Maps API, Geocoding API, Directions API, and Distance Matrix API for accurate location-based features and optimized routing. I stay current with industry trends and best practices, bringing a continuous-improvement mindset to every product.
