About Me

Building at the edge of code and infrastructure

I'm an IT Engineer and Senior Web Application Developer from Kolkata, India with a B.Tech in Information Technology from Guru Nanak Institute of Technology (CGPA: 8.17). Currently, I serve as Senior Web Application Developer at Ib Arts, leading backend architecture and DevOps systems. Since 2021, I've co-founded digital agency WEFIK, led dev teams in esports, interned in document QA at ARC, and engineered software for global clients.

My work spans the full stack: React/Next.js frontends, Node.js/Laravel APIs, MongoDB and MySQL databases, Linux server administration, and increasingly — AI integrations and IoT systems. I hold 30+ certifications across CompTIA, TryHackMe, Coursera, and Udemy.

In 2025, I was granted a patent for an IoT-based solar-powered vaccine preservation system — built with NodeMCU, MQTT, and Peltier cooling for off-grid healthcare supply chains.
