01 — About
Who I am
Full Stack Engineer with hands-on experience across the stack — React.js / Next.js on the frontend and Node.js (NestJS, Express, AdonisJS) on the backend. I design RESTful APIs, model and optimize relational databases (MySQL, PostgreSQL), and build AI-driven products with RAG, vector search and LLMs. A competitive programmer with 2000+ problems solved across Codeforces, LeetCode and AtCoder, I bring strong data-structures-and-algorithms fundamentals to everything I ship.
