Summary

Senior Full-Stack MERN Developer with over 10 years of experience architecting and delivering reliable, scalable web applications using MongoDB, Express.js, React.js, and Node.js across the full software development lifecycle. I specialize in crafting responsive, cross-platform interfaces with HTML5 and CSS3, ensuring accessibility and smooth user experiences.


My expertise extends to backend systems architecture using Node.js and Express.js to build RESTful and GraphQL APIs that support high-throughput business operations. I’ve built real-time features using WebSockets and Socket.IO for transaction updates and notifications, with secure authentication powered by JWT and OAuth.


In past roles, I’ve optimized backend performance by adding Redis caching and background job handling with RabbitMQ. PM2 helped manage service restarts and uptime. I follow code best practices through static analysis and reliable test coverage (Jest, Mocha, Chai, React Testing Library, Cypress) and am experienced in CI/CD automation (Jenkins, GitHub Actions, BitBucket) and cloud deployments on AWS, Azure, and Google Cloud, utilizing Docker and Kubernetes for containerization and orchestration.
