Dhaka, BD — Open to roles
NETWORK & INFRASTRUCTURE ENGINEER

Enterprise networks that stay up, secure, and documented.

I design, deploy and maintain LAN, WAN, WLAN, VPN and SD-WAN systems across government, campus and logistics environments — from core switching to the diagrams that explain it afterward.

// OVERVIEW

Summary

Grounded in enterprise networking, hardened by government-scale security requirements.

I'm an IT professional based in Dhaka with hands-on experience across telecommunications and enterprise network infrastructure — LAN, WAN, WLAN, VPN and SD-WAN — built for organizations where downtime isn't an option: a national finance ministry, a university campus, and logistics operations running 24/7.

My work spans the full lifecycle of a network: designing the topology, configuring multi-vendor hardware, securing it against real threats, and writing the documentation that lets someone else maintain it after I've moved on. I currently support the Finance Division's core systems while working toward Azure and advanced routing certifications on the side.
