About Me

I’m Aditya, a competitive programmer and full-stack developer who enjoys tackling challenging problems and building efficient systems. My journey started with data structures & algorithms and quickly evolved into a deep interest in optimizing solutions and thinking at scale.

I actively participate in contests on platforms like Codeforces and LeetCode, where I focus on writing clean, optimized C++ solutions and improving my problem-solving speed and accuracy. Competitive programming has shaped my ability to break down complex problems and approach them logically.

Alongside CP, I build full-stack applications using the MERN stack and Next.js, combining strong backend logic with clean frontend experiences. I enjoy working on systems that are both scalable and practical.
