Case Study

How a bash launcher, a GitHub Actions workflow and a directory convention became a fleet-wide update machine 🤖

How I moved 1,273 repositories, full Git history and CI/CD included, with a Bash engine wrapped in a Temporal harness 🚚

A human drags a JIRA card, a Temporal workflow moves on. The prototype behind a bank's choice 🤝

Five weeks of hand-written validation, replaced in two days by rules that read like sentences : 1,799 lines deleted, and a DSL that kept growing without me ✅

A Scala hello world that couldn't fit in 250 MB sparked a move to Go. 25 services later, the team runs them without me 🐹

Change the code, replay the history. More than three billion events a year, and nothing to operate ☁️

Recruiters stopped receiving our alert links, so we built a shortener in three weeks : one bucket as the store, a 301 as the whole read path, and nothing to operate 🔗
