System Engineer » |
Building robust network infrastructure, automating systems with DevOps practices, and contributing to open-source projects. CCNA, MTCNA & CompTIA A+ certified.
I'm Zia Uddin Zisan, a System Engineer based in Chattogram, Bangladesh. Currently working as an Embedded Network Engineer at Mux Technologies Ltd, I manage and maintain network infrastructure while providing remote support and monitoring network health.
I maintain a forked build of Paranoid Android (AOSPA) — a customized Android OS — where I cherry-pick commits, merge upstream changes, and build custom ROMs for specific devices. I'm also a DevOps trainee focused on automating workflows, monitoring system performance, and optimizing deployment strategies. I'm always seeking opportunities to build and maintain scalable infrastructure.
My expertise spans MikroTik RouterOS (MTCNA certified), CompTIA A+, Linux server administration, and network security. Currently pursuing my BSc in Computer Science & Engineering at University of Creative Technology, Chittagong.
