Projects
Self-Hosted Infrastructure & Email Deliverability
I run a Debian homelab and web/mail infrastructure serving more than a dozen domains. I corrected DKIM, SPF, DMARC, and reverse DNS after outbound mail failed authentication at Gmail and Microsoft, restoring authentication and delivery across the hosted domains.
Embedded-device investigation
An independent 2023 investigation used Nmap/Zenmap for service discovery and Telnet for embedded Linux inspection. I imaged SD media and used Disk Drill to inspect recovered files and export a deleted thumbnail.
