Case Study
CI/CD Governance Hardening
Delivery quality was inconsistent due to manual exceptions and unclear ownership.
Problem
Releases bypassed test gates, incident handoffs lacked structure, and postmortems were not actionable.
Solution
- Made lint, type-check, integration, smoke, and Lighthouse gates blocking
- Defined rollback drill cadence and release ownership model
- Standardized release report and incident evidence templates
Result
No emergency rollback over 30 days and mean release lead-time reduced by 34%.
Role
Pipeline governance design, standards implementation, and release enablement.
Tech Stack
GitHub Actions, Playwright, Lighthouse CI, Node.js, Nginx.
Proof
Release dashboard snapshots, CI pass/fail history, and drill evidence were shared in weekly governance reviews.
Lessons & Tradeoffs
Stricter gates slightly increased pre-release effort but removed far larger post-release firefighting costs.
