Senior developer · AI systems builder · product thinker
I’m Callum: a senior WordPress developer and systems architect with 20+ years building digital products, custom software, and the workflows behind them. I connect strong engineering with clear thinking and a sharp eye for the person using the thing.
A few things I’ve been making
I like the hard middle: where a promising idea meets real users, real constraints, and the question of how to make the whole system feel effortless.
A desktop journal and email experience for people who want digital communication to feel personal again. Scrapbook inspired tools, expressive stationery, and a warm writing flow turn a note into something worth keeping.
A Windows system analyzer built around evidence and user control. It explains what it finds, previews changes before they happen, and designs repair workflows around backups, verification, and undo.
A centralized operations hub concept for managing multiple WordPress sites: updates, quality checks, client communication, and recurring work in one coherent view.
A product studio for RedM roleplay communities, exploring practical tools that give players more reasons to interact: crafting systems, field indexes, overlays, server QA, and story-rich workflows.
AI that earns its keep
My AI work starts with a real workflow and a clear definition of “better.” I’ve developed custom agents, prompt systems, structured datasets and training corpora, AI-assisted operations, and automation concepts—including exploration of local language models.
I bring product judgment and engineering discipline to the same table: what should be automated, where a person needs control, and how to make the result maintainable after the demo.
Task-focused agents, instruction design, and guardrails shaped around a useful job to be done.
Structured knowledge, training corpora, and content models that make information easier to use.
Connect tools and services with APIs, event-driven flows, and clear failure handling.
Turn AI capabilities into approachable interfaces, review steps, and real-world product behavior.
The long view
Across product teams, agencies, and independent work, I’ve stayed close to both the code and the people depending on it.

Next good problem?
I’m looking for a remote role where deep technical work, product thinking, and thoughtful collaboration belong in the same conversation. If that sounds like your team, I’d love to hear from you.
