Multi-Repo to Monorepo: How I Automated 6 Go Microservice Releases and Then Made It 15x Faster

Last month I spent more than an hour cutting a release across six Go microservice repos. Tag log, wait for CI. Update sdk's go.mod to point at the new log SHA, push, wait for CI. Repeat for utils. Then do api, cli, and worker in parallel - except I forgot to bump cli's dependency and the build broke at 11pm.

That was the last manual release I did.

This is the story of automating that entire workflow with Jenkins + Python + GitLab, then realizing the multi-repo architecture was the real problem, and collapsing everything into a Go monorepo that's 15x faster at cutting releases.

The full setup runs on my laptop. You can fork it and try it yourself.
