Well for me, all of my actual implementation work has been green field from “git init” and mostly coding around the AWS SDK in the target language and infrastructure as code since AI coding has gotten decent.
I haven’t had to write a line of code in a year. First ChatGPT and more recently Claude Code.
I don’t do “agentic coding”. I keep my hands on the steering wheel and build my abstractions and modules up step by step. I make sure every line of code looks like something I would write.
I’m a staff consultant (cloud + app dev) and always lead projects, discovery and design and depending on the size of the project, do all of the actual hands on work myself.
I would have had to staff at least one maybe two less senior consultants to do the actual hands on work before. It’s actually easier for me to do the work then having to have really detailed requirements and coordinating work (the whole “Mythical Man Month” thing).
FWIW: before the pearl clutching starts, I started coding in assembly in 1986 on an Apple //e and have been delivering production level code since 1996.
