Profile

Hi, I'm Yash — software engineer driven by performance and clarity.

I am currently pursuing M.Tech in Computer Science and Engineering at IIIT Delhi. My primary programming languages are C++ and Java. Previously, I pursued a B.E. in Computer Science at Thapar Institute of Engineering and Technology, where I built a strong foundation in CS fundamentals. With over 500 unique DSA problems solved on LeetCode and Naukri Code360 and ranked “EXPERT” on Codeforces, I have a solid grasp of data structures, algorithms, and competitive programming (also 4-star on CodeChef). My journey reflects a commitment to learning and excellence: JEE Advanced 2019 (AIR 7.8K), JEE Main 2019, PGCAT 2025 (AIR 39), and CAT 2024. I’m excited to apply my skills to challenging, real-world problems and contribute meaningfully to the tech industry.
