With over 40 years as a coder, Ryan Hamilton is a senior software engineer on the AI Team at CircleCI. Spending most afternoons after school at his father's software store in the early 80's, he started writing code in second grade on an Apple II in BASIC, and has been coding in countless capacities ever since.

For him, "software delivery" has meant everything from shipping floppy disks to brick-n-mortar outlets in cardboard boxes to YOLOing AI-generated apps into production on straight-up vibes, but he believes that there are certain timeless SDLC principles that have remained intact through it all.
