About Me

I'm a software engineer with a passion for building products that make a real impact. Currently, I'm a Founding Engineer at ContraVault AI, where I'm helping build the next generation of tender analysis technology infrastructure.

My journey in tech started with a B.Tech in Electronics and Communication Engineering from NSUT, where I specialized in IoT. Since then, I've worked across the full stack - from crafting intuitive user interfaces to designing robust backend systems that handle thousands of requests daily.

I believe in writing clean, maintainable code and building systems that scale. My expertise includes cloud architecture, distributed systems, and modern web technologies. When I'm not coding, you can find me creating educational content on my YouTube channel or exploring new technologies.
