Docker Makes life of Developer Easy!!!!

I’m Swapnaneel Kundu, a full-stack developer with a strong focus on backend development using the MERN stack. I’ve independently built and contributed to real-world projects, including a complete backend system of some services of Hosla and shraddha wellfare NGO. I focus on writing clean, modular, and production-ready code. My work includes implementing authentication with JWT and cookies, building custom error handling layers, using Joi for validation, and integrating logging with Winston. I’ve also worked with Socket.IO for real-time features and used Postman extensively for API testing. Beyond that, I’m expanding into areas like system design, PostgreSQL, Redis, and infrastructure tools like Docker and Kubernetes. I also have working knowledge of React and Tailwind CSS on the frontend.
