Senior Linux Systems Administrator with 20 years across mixed Linux, Windows, and cloud environments. The day-to-day stack is Python, Bash, Ansible, and Docker, monitored with Prometheus, Grafana, and Azure Monitor on Red Hat and Ubuntu. I codify baselines with Ansible and automate provisioning and operations in Python. On the network side I run VLAN segmentation, inter-VLAN routing, OSPF, NAT, and precise access lists. I also ship AI into production, RAG systems over client knowledge bases built in Python on a vector database, with Claude Code in daily development.
