👋 About Me!

Hey there! I'm a Senior Software Engineer Based in Chennai | Originally from Kolkata

I'm a passionate Senior Software Engineer with a strong focus on buildingelegant, performant, and scalable web applications. With over three years of hands-on experience, I've had the privilege of collaborating with world-class teams at NexSemi Systems, Logitech,Atonarp, Charger Logistics, and ShipHaul Logistics.

My journey spans across frontend and full-stack development. From designing responsive UI components in React, Next.js, and Angular, to writing backend logic in Node.js and Python, I love building experiences that work and delight users.

I write modular, reusable components and follow best practices to deliver scalable code. I'm deeply invested in JavaScript fundamentals and bring that knowledge to tasks like optimizing large uploads, managing state, or animating UIs with Flexbox,CSS Grid, and SCSS. I focus on performance, accessibility, and a solidUI/UX foundation. I work well in Agile/Scrum teams, write tests, and use tools like Git, Docker, and gRPC in my day-to-day development.

⚽ Outside the Code

When I'm not coding, you'll find me on the football field, catching up on matches (huge Manchester United and KKR fan!), exploring new places, or lost in a good book.

🚀 Let's Collaborate

I love turning ideas into intuitive, functional software. Whether you're building something new or refining a product, I bring technical depth, user empathy, and arelentless attention to detail.
