Who I Am

I'm a third-year Computer Science student with a sharp focus on both competitive examinations and industry-ready skills. GATE prep keeps my fundamentals ironclad, while DSA practice keeps me sharp for product company interviews.

On the dev side, I work with Python, Django, and DRF to build robust REST APIs. My current obsession is the world of Large Language Models — specifically how RAG (Retrieval-Augmented Generation) can make AI more accurate and useful in real applications.

I believe in learning by building. Every concept I study, I try to implement in a project.

Things I've Built

002
AI LeetCode Documentation Generator
Built an AI-powered developer tool that converts raw LeetCode solutions into structured documentation. The system analyzes code using Google Gemini, detects problem metadata, identifies algorithmic approach, and generates GitHub-ready explanations with time and space complexity.
Django REST API Gemini 2.5 JavaScript Prompt Engineering AI Automation
001
RAG Document QA Bot
An intelligent Q&A system that lets users upload PDFs and ask questions. Uses vector embeddings for semantic search and LLMs for accurate, context-aware answers.
