Selected technical work.
This is where I keep technical work I want to be able to point back to that does not fit cleanly under the lab or writeups sections. Some of it is security work, and some of it is general IT, networking, or troubleshooting.
Kiloview E3 unauthenticated factory reset
I found and manually validated an unauthenticated administrative API endpoint, disclosed it to the vendor, followed the remediation, and later received a CVE.
Windows system failure — file recovery
I used WinRE and command-line tools to recover important files from a non-booting Windows system before attempting repair.
Dedicated OPNsense router / firewall
I built a dedicated firewall on repurposed OptiPlex hardware and worked through NIC compatibility, interface assignment, and validation.
Pi-hole DNS sinkhole
I built a network DNS control point for filtering, visibility, and encrypted upstream resolution.
WireGuard homelab gateway
I moved remote access behind a VPN instead of exposing individual internal services directly to the Internet.
