About Me
I'm an IT professional currently working as an NVIDIA GPU Server Repair Technician at SMS InfoComm Corporation, Grapevine TX. I perform root-cause analysis, component-level repairs, and multi-cycle performance validation on production GPU servers.
I hold a B.Sc. in Computer Science & Engineering and love building real infrastructure skills through my personal home lab — running Pi-hole, Unbound DNS, Docker, Plex, and VPN on Linux.
I'm growing toward network engineering and IT infrastructure roles with a solid foundation in TCP/IP, Active Directory, and Linux.
