Oracle Cloud Infrastructure / GPU clusters / Fiber diagnostics
Collin Rentz
I support Oracle Cloud AI infrastructure, from dense GPU rack environments to the optical links, switch health checks, and automation that make complex networks easier to troubleshoot.

Current Work
Operational clarity for complex AI infrastructure.
I work across live GPU facilities where hardware, optics, power, cooling, and network behavior all have to make sense quickly. My focus is turning noisy failure states into clear next actions.
Fiber and Optics
Trace high-density links, validate optical power, and isolate loss across spine-leaf networks.
Automation
Create internal scripts that accelerate switch health checks and break-fix diagnostics.
Turn-Up Support
Assist with deployment, validation, and expansion work for dedicated AI infrastructure buildings.
Infrastructure
Turning rack-level signals into fabric-level clarity.
The work is physical and analytical at the same time: tracing cables, swapping optics, interpreting switch telemetry, validating link health, and documenting patterns so the next fix moves faster.

Senior Data Center Support Services Technician Oracle
Support OCI AI infrastructure, diagnose switch and optics issues, build automation for health checks, and assist with new AI facility deployment and turn-up.
Infrastructure Repair Technician EOS / Meta
Resolved live network hardware incidents, traced fiber circuits, analyzed optical loss, managed RMA workflows, and mentored newer technicians.
Data Center Technician TEKsystems / ZT Systems
Installed and maintained NVIDIA DGX and H100 systems with structured cabling, airflow, power balancing, and InfiniBand cluster support.
Projects
Tools and apps with a practical core.
Internal operations tool / Switch diagnostics
ÆtherNet Switch Diagnostics
Pronounced like "Ethernet"; a name that blends Aether, the idea of something connecting across space and time, with Net for network.
ÆtherNet is an internal switch diagnostics tool I built from real data center troubleshooting pain points. It accepts a switch/interface pair or ticket-style connection string, follows the appropriate access path, collects diagnostics, and formats the result into a readable terminal view.
Designed to make switch and fiber troubleshooting faster, clearer, and more repeatable for technicians without exposing sensitive internal details.

BabySphere
An iOS app for young children to explore color through a simple, tactile interface and playful 3D motion.

Portfolio / Art Direction
Adhesion Art
A visual identity and portfolio concept for digital and acrylic artwork, pairing personal craft with strong graphic contrast.
About
Technician, developer, artist, husband, and father.
I like work that rewards patience and precision. Data centers taught me to move carefully inside complex systems. App development taught me how to shape ideas into tools. Art keeps me willing to experiment.
The best version of my work blends all three: practical, reliable, and visually considered.
Art
Creative range outside the server aisle.
