Hi — I'm Archer.

I'm a maker, a breaker, and a sometimes fixer. I've been programming since I was nine, and was shit for a very long time — but I like to think I'm a better engineer than 13-year-old me.

I describe myself as technology-agnostic — generalist by capability, opinionated by taste. I tend to reach for whatever will actually get a thing shipped, and I enjoy the shape of problems more than the language I solve them in.

My specialty is applied AI: building systems that use LLMs reliably, safely, and with genuine leverage. Most of what I find interesting sits at the seam between product and model — prompts, evals, tool use, the plumbing around a model that decides whether it actually works in production.

My philosophy on software is simple: build rapidly, clean up, repeat. Planning is vital, but you can never predict every aspect of a project — the aim is to ship something real, figure out what went wrong, and do it better next time.

Right now I'm a co-founder at Doccy and Medlo, where the mission is simple: 4.6 billion people don't have access to essential healthcare, and we want to close that gap by bringing quality, accessible care to everyone, everywhere. Before that I built business & automotive software for tier-0 OEMs, and before that I freelanced and worked on security-focused software.

I make time to write little utilities, extensions, and plugins for open-source frameworks — and sometimes I actually finish them. Lately I've been focused on large language models and how we as an industry can make human <-> LLM interaction feel less adversarial and more genuinely useful.

No engineer is perfect, and I'm no exception. There's a long way to go before I'd consider myself great, but I'm trying to get there as fast as I can (no fear of failure here).

I'm deeply interested in startups, business, and the places where technology bends a market. I want to build things with real leverage — products that compound, infrastructure people quietly depend on, and the occasional weird side quest.

I'm also unapologetically patriotic about Melbourne and about Australia. I think this is one of the best places on earth to build from, and I want to see far more ambitious software come out of here. Expect some of my writing to wander into that. As long as I'm making cool things, I'm happy.
