Hello, world.

I’m Matt, a Principal Engineer at AWS here in Melbourne, Australia 🇦🇺. This blog is where I write up the work that’s held up.

Most of my time goes on Python tooling and AI agents, fine-tuning open-source vision models like Qwen on a Framework Desktop, and a homelab I keep finding reasons to expand. At work and at home I build on AWS, mostly with CDK. When something actually works, I try to write up how and why it did.

Expect posts on fine-tuning local models, building simple things on AWS that scale well and follow good practice, and the odd homelab share to break things up. I talk about a lot of these topics at meetups and conferences too, like AWS re:Invent and PyCon AU, and sometimes on YouTube.

def hello() -> str:
    return "hello, world"

About the name: coles.codes. It’s a bit ironic now, because I don’t write much of it by hand anymore. I spec it out, prompt an AI, and edit what comes back. I’ll still write a paragraph of code myself here and there where it makes sense too!

The site is kept simple: a Hugo theme I built myself, hosted on S3 and CloudFront, with the infrastructure defined in CDK. It’s all open source and currently hosted on my GitHub .

More soon.
