About Me

A glimpse into my journey

I'm a Computer Science student at IIT Patna with a deep passion for competitive programming and algorithmic problem-solving. My journey in tech began with curiosity about how things work, and has evolved into a commitment to mastering data structures and algorithms.

When I'm not coding, you'll find me participating in coding contests on platforms like Codeforces, CodeChef, and LeetCode, constantly challenging myself to think differently and optimize solutions.

I believe in continuous learning and pushing boundaries, which has helped me solve 800+ problems across various platforms and achieve notable rankings in competitive programming contests.

Computer Architecture

SIMPLEX Assembler & Emulator

Designed and implemented a Two-Pass Assembler and a custom machine Emulator for the SIMPLEX instruction set architecture. The assembler performs symbol resolution, error detection, and machine code generation, while the emulator simulates execution with stack operations, branching, and memory management.
