QA & testing

The unglamorous work that keeps your weekends free.

What we do

Testing infrastructure that catches regressions before they reach production. Release pipelines that turn deployments into a non-event. Monitoring that pages someone before your users notice.

Most teams underinvest in this work because it never feels like the most urgent thing — until something breaks at the worst possible moment. We help you do the boring work that prevents the exciting incidents.

How we typically engage

  • Test automation buildouts. A real test suite — unit, integration, end-to-end — wired into CI and trusted by your team. Not a thousand flaky tests that everyone learns to ignore.
  • CI/CD pipelines. Deployments that are fast, reproducible, and rollback-safe. We’ve seen enough of the alternative.
  • Load and performance testing. Realistic load profiles, identified bottlenecks, documented headroom. Especially valuable before launches or seasonal peaks.
  • Quality engineering as a practice. Embedded with your team for a quarter or two, leaving behind both the infrastructure and the habits.

Tools we use

  • Test runners. Jest, Vitest, Playwright, Cypress, JUnit. Whatever your stack speaks.
  • CI. GitHub Actions, GitLab CI, occasionally Jenkins (when we have to).
  • Load. k6, Locust, JMeter.
  • Monitoring. Prometheus + Grafana, Datadog, Sentry.

A note on testing philosophy

We don’t believe in 100% coverage as a goal. We believe in covering what matters — critical paths, edge cases that have bitten you before, integrations that are likely to drift. A small, fast, trustworthy test suite is worth more than a giant one nobody runs.
