Case Study

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

How I moved an entire data platform — full git history, CI/CD included — with a bash engine wrapped in a Temporal harness 🚀

The JIRA board is the workflow UI, a human dragging a card is the signal — the prototype behind that decision 🤖

Five weeks of hand-written validation, replaced in two days by rules that read like sentences — one rule set for POST and PATCH, errors that name the field, 1,799 lines deleted, and a DSL that kept growing without me 🚀

A Scala hello world killed in a 250 MB pod, a tracker ported to Go in one evening, and the group's second revenue product rebuilt as Go services next to its legacy, then drained — 25 services later, a team runs it without me 🚀

Raw events kept forever, everything else a version — change the code, trigger one DAG, and the history is replayed while live events keep flowing ; more than three billion events a year, and nothing to operate ⏱️
