Work History

June 2026

1 Commits • 1 Features

Jun 1, 2026

In June 2026, delivered a governance page update for the godot-website to reflect the current organizational structure: added new board members, removed the advisory committee, and established the Technical Leadership Committee (TLC) to oversee leadership roles. This change improves governance clarity, transparency for contributors and external stakeholders, and decision-making speed by aligning the public-facing governance page with the actual org structure. The update was implemented via a single, auditable commit (23c905374185302fa32699d1a6f93243d832b4c6) referencing issue #1358, ensuring traceability and alignment with project workflows.
