Works on My Machine

Notes from inside developer platforms. IDP, CI/CD, DX, and the gaps between them.

I’m Angel Cantu, a Software Engineer. I work close to the platforms other engineers depend on, and I write down what I learn there — what shipped, what broke, and what was less obvious than it looked.

Why This Blog Exists

This is my web journal from working inside developer platforms — internal developer platforms, CI/CD, and the developer experience around them. I write to contribute back by sharing practical lessons, patterns, and mistakes others can learn from. “Works on My Machine” is partly a joke, partly a method: build, test, break, learn, repeat.

What You’ll Find Here

Build

Projects, prototypes, and technical experiments I’m actively working on. What I shipped, the tradeoffs I made, and what I’d change next time.

Write

Technical notes and breakdowns in plain language. Architecture decisions, implementation details, and lessons that survived contact with reality.

Journal

Reflections from the day-to-day process. What I’m learning, what I’m rethinking, and how my approach evolves over time.
