About

I am a Computer Science undergraduate from Netaji Subhash Engineering College, with a strong foundation in data structures, algorithms, and scalable system design. My interests lie in backend development, cloud infrastructure, and AI-assisted tooling. Currently, I am a Teaching Assistant at both AlgoZenith and ChaiCode, where I support a community of over 2,000 learners by resolving hundreds of DSA queries monthly and developing comprehensive problem editorials. I recently completed a Site Reliability Engineer internship at Google, where I built an internal tool using C++, TypeScript, and Cloud Spanner. This tool reduced critical data lookup times from over 3 minutes to less than 15 seconds, significantly improving on-call debugging speed by 20%. My experience also includes working as a freelance AI Trainer at Outlier, where I enhanced AI model accuracy by 15%. Key Highlights: - Proficient in C++, Java, Python, JavaScript, TypeScript - Experienced with React, Node.js, MongoDB, MySQL, and GCP - Built a Rubik’s Cube Solver using Korf’s IDA* algorithm (solves in under 10 seconds) - Developed a Drawing App using React, Canvas API, and Tailwind CSS - Ranked in the Top 1% globally on LeetCode (Guardian) - Achieved Global Rank 271 in TCS CodeVita and 227/35,904 in LeetCode Biweekly 140 I am passionate about building efficient systems, mentoring learners, and solving real-world problems through technology.
