Hello! I'm Lalit 👋

I'm a network engineer with over a decade of experience in Unified Communications and networking, based in Pune, India. Beyond my day job, I love experimenting with various technologies as a hobby and building personal projects.

This is an extension of my main blog lalitwrites.com — a focused space for my networking notes: the fundamentals, the protocols, and the troubleshooting lessons learned along the way.
