I'm a backend developer based in Kolkata with over 4 years of experience in building scalable and efficient web applications, during which I have successfully worked/delivered more than 10+ projects. I primarily work with backend technologies like Node.js, Express, Nest.js, TypeScript, and JavaScript to develop robust APIs and server-side functionality. On the front end, I've started learning React and have built a few small applications to get hands-on experience. In my projects, I use databases like MongoDB, PostgreSQL and MySQL depending on the requirements. For development, I rely on tools like Git for version control, VS Code as my main code editor, and Postman for testing and debugging APIs. I'm always eager to learn new technologies, refine my skills, and stay updated with best practices to deliver high-quality solutions.
