Senior Web and Linux Administrator
University of Toronto, Faculty of Dentistry, IITS
Fifteen-plus years keeping healthcare IT running. Unix and Linux, PHIPA and PCI DSS, the payment stack, and the scripts that glue it. Now the architectural frameworks behind Faculty systems.
Lately that sits next to local AI: Ollama and Open WebUI on hardware he can point at, plus the usual vendor APIs when a job needs them. The appeal is not magic. It is work that stays useful when the network does not.
