At TaskUS, I resolved enterprise IAM issues involving SSO, MFA, and password resets using Ping Identity, cutting resolution time by 25%. I also supported remote users and virtual desktop environments.

In my networking projects, I deployed a pfSense router with VLAN segmentation, QoS traffic shaping, and Suricata IDS/IPS. I used Wireshark for packet-level threat analysis.

I managed a Proxmox platform with 20+ VMs and containers and automated provisioning to reduce setup from hours to minutes. I also built a Pi-hole DNS sinkhole that blocked 89% of malicious domains and ad queries across the local network.
