01. About Me

Hey! I'm Kratik Jain, a full-stack engineer and ECE graduate from Indore, India. I graduated from NIT Surat in 2025 and I'm currently working as a System Analyst at NSE Clearing Limited in Mumbai.

I love building things that live on the internet — whether that's interactive web apps, Telegram bots, AI assistants, or developer tools. I'm most productive when I'm turning an idea into a product that people actually use.

When I'm not coding, you'll find me solving DSA problems (1591 on CodeChef, 219+ problems across platforms), contributing to open source, or exploring new tech.
