Eyüp Yıldız

Freelance DevOps & Test Automation Engineer · Oosterhout, NL

I build the test suites and the delivery pipelines they run in. Mostly for large organisations where a bad release ends up in the news rather than in a retro.

Clients include TenneT TSO, Nationale Nederlanden, a.s.r., DELTA, Johnson & Johnson, KVK and Efteling.

Most teams do not lack tests. They lack tests that run fast enough to matter, fail clearly enough to act on, and sit inside the pipeline where they cannot be skipped on the week the deadline lands.

What I get hired for

  1. Test automation: api, ui, service, contract, fast enough for every commit
  2. CI/CD and delivery pipelines: gates that block by default, one documented override
  3. Test reporting and analysis: failures that name their cause, flaky tests traced and fixed, results a team acts on
  4. Development and infrastructure: code alongside the team, environments defined in code so staging means something
