CI/CD pipelines, PRs ship preview environments, merges ship to production.

CI/CD is the invisible product that decides whether the development team feels like they're shipping or fighting the pipeline. We build the pipeline so the default path is fast, the failure modes are obvious, and the production deploy is one merge button, not a calendar invite.

What we build

  • Preview environments per PR

    Every pull request gets a unique deploy with seeded data. Designers, PMs, and stakeholders review the actual product, not screenshots. The preview URL goes in the PR description automatically; teardown happens on merge or close.

  • Test sharding that keeps the build under five minutes

    Unit, integration, and e2e tests fan out across parallel workers. The pipeline targets a 5-minute total even as the test suite grows. Slow tests get profiled and either sped up or moved to a nightly suite, they don't tax the main loop.

  • Build cache that actually works

    Layer caches, task caches, and artifact caches configured against the work that actually changes. Cold builds rare; warm builds quick. We measure cache hit rate as a CI health metric.

  • Required checks that catch what matters

    Typecheck, lint, test, build, non-negotiable. Plus performance budgets for the marketing surface, automated accessibility checks to catch regressions, bundle-size limits where they matter. The check list is short on purpose; every check has to earn its place.

  • Blue/green production deploys

    Production deploys promote the green build with traffic-shift, not in-place restart. Rollback is a single command that flips the active color back. We've never told a customer 'we're rolling back, please wait an hour'.

  • Deploy notifications that are useful

    Slack notifications include the diff link, the commit author, and the rollback button. When something goes wrong at 3am, on-call sees what changed and what to do, not 'deploy failed, check the logs'.

Where this fits

  1. Your CI takes 20+ minutes per PR and engineers are context-switching while they wait.

  2. Your production deploys are manual and the team has been bitten by the same rollback issue twice.

  3. You're hiring designers and PMs onto the team and they can't review work without an engineer to spin up an env.
