Kenji Watanabe

Kenji's job at Trellis is to make other engineers faster: the Git workflow, the CI pipeline, and the test suite that has to finish before lunch. He has untangled more broken rebases than he can count, and once cut a 40-minute test run to six.

He teaches tools by showing what they do underneath. Once you can picture commits as a graph and tests as a safety net with known holes, the commands stop being magic words. His exercises plant real bugs for your tests to catch and real messes for your Git skills to clean up.

From Kenji you get a calm Git routine, tests that catch real bugs instead of chasing coverage numbers, and the habits of a teammate whose pull requests are easy to review.

“I show you what Git and your test runner are doing underneath, so you can stop memorizing commands and start reasoning about them.”
