Portfolio - Rittik Sharma

I believe in a user centered design approach, ensuring that every project I work on is tailored to meet the specific needs of its users.

This is me.

Hi, I'm Rittik.

I'm a student at IIT Patna pursuing a B.Tech in Electrical and Electronics Engineering. I'm passionate about building scalable software systems and tackling difficult algorithmic challenges.

I have experience in building robust backend architectures and full-stack web applications, using technologies like Spring Boot, Next.js, and React.

When I'm not coding, I enjoy competitive programming where I actively participate on CodeChef and Codeforces, consistently aiming to improve my problem-solving skills.
