May 2026 highlights for coder/coder focusing on security, access control, and reliability. Delivered two high-impact features with strong security posture and added tests, driving reduced risk and clearer ownership in product actions.

April 2026: Delivered core CI/CD reliability, security hardening, CSP embedding improvements, and UX/documentation updates for coder/coder. Work enabled smoother deployments, safer automation, and clearer user guidance. Key contributions span CI/CD workflow upgrades, CSP frame-ancestors controls, terminal command confirmation UX, and MCP SSH permission enforcement, with concrete commits across multiple areas.

March 2026 (coder/coder) focused on security hardening, user experience improvements for cryptographic verification, and clearer policy error semantics. Delivered three concrete changes with strong business value: (1) CI/CD security hardening by removing the Trivy GitHub Actions job to reduce supply-chain risk, (2) GPG verification UX improvement by explicitly trusting the release key to suppress untrusted-key warnings, and (3) policy error handling improvement by returning 403 Forbidden for blocked private IP policy cases. All work is traceable to specific commits for auditability and incident response context.
