Learning. Building. Improving.

Hi, I’m Swastisunder 👋 I’m a full-stack web developer focused on building clean, modern, and practical web applications. I work mainly with the MERN stack (MongoDB, Express, React, Node.js) and enjoy turning ideas into real, usable products. Right now, I’m also learning Python and AI/ML, one concept and one project at a time. Always learning. Always building.
