01 · About Infrastructure engineer.
Infrastructure engineer.
Writer by passion.
I design, secure and run the infrastructure that businesses depend on every day — and I write to make technology understandable for everyone.
For more than 13 years I have worked across enterprise IT infrastructure, data center operations, system administration, networking, cyber security and end-user support. My work centers on Windows Server, Active Directory, firewalls, virtualization, backup & disaster recovery, CCTV systems and IT asset management — with one goal: secure, resilient, business-aligned IT.
Beyond the server room, I am the founder of BangladeshPrime.com and BangladeshPrime Learning, where I write and teach technology in Bengali. I also build internal tools, write books, and keep exploring cloud, SOC & incident response, digital forensics, AI and automation.
