CI gates that scope lint, typecheck, tests and build to the merge-request diff, rolled out to two repositories on the same day. Before that, the first CI/CD pipeline of a company that deployed by hand.

◆ PipelineRunner
Run the pipeline and compare before and after the merge-request gate I built: lint, typecheck, tests and build scoped to the MR diff, caching only the package-manager store. The times are the measured ones.
Every MR verifies only the files in the diff (git merge-base) and caches only the package-manager store.
Company VPN
Internal servers are reachable only through the VPN, which I run.
Self-hosted GitLab
Upgrades, daily backups and rollback runbooks are on me.
MR gate
Lint, typecheck, tests and build on the diff; blocking before merge.
Production on DigitalOcean
DevOps access across the production environments.
Demo with fictitious data: no real clients and nothing from production.
Lint, typecheck, tests and build scoped to the MR diff, made blocking in two repositories on the same day.
Production deployments were manual and unverified; the pipeline automated build, tests and deploy.
I run the self-hosted GitLab (upgrades, daily backups and rollback runbooks) and the company VPN.
Pipeline author
GitLab pipeline that scopes lint, typecheck, tests and build to the merge-request diff and fails loudly when the change list comes back empty. Blocking in two repositories.
