PROFILE

Andrew Dunham

Worked on the tailscale/tailscale repository, delivering five features and two bug fixes over four months focused on backend development and reliability. Built advanced map cloning and view type handling in Go, improving nested map support and view retrieval. Enhanced DNS resolver observability with debug logging and modernized dependencies to reduce technical debt. Implemented secure credential retrieval from AWS Parameter Store and added DNS-over-HTTPS support via CIRA Canadian Shield, strengthening security and privacy. Addressed test flakiness, kernel-version compatibility, and improved error handling. Delivered a Debian PATH fix to enhance user experience, demonstrating depth in Go, networking, and API development.

Work History

April 2026

1 Commits

Apr 1, 2026

April 2026 monthly work summary for the tailscale/tailscale project, focusing on reliability and user experience improvements for Debian users. Delivered a targeted PATH fix to ensure game directories are included in the default PATH, improving game discovery and user experience on Debian. Validation was performed on a modern Debian install, with the change documented and traceable via commit notes (Change-Id). This work emphasizes quality, reliability, and cross-distro consistency. No major feature work completed this month beyond the bug fix; the effort reduces friction and potential support overhead related to missing game directories.
