About

I’m Jamie Scott Craik, a software development student and former Warrant Officer Class 1 living in Middle Rasen, Lincolnshire.

Evolve

Twenty-two years in the Army took me from chef to instructor, infantry soldier, senior instructor, squadron sergeant major, logistics manager and service delivery manager.

Now I study software development and build AI skill tools with Codex, OpenAI’s coding agent.

I’ve been developing independent software projects since November 2024. My main projects are Skills SDK, a Python tool that checks AI agent skills before they’re shared or installed, and SkillsProof, a macOS menu-bar app that brings those results together.

I use Codex, an AI coding agent, to write most of the code. I set the requirements, review the changes and take responsibility for testing and documentation.

I’m studying a full-time BTEC HNC in Digital Technologies for England, on the Software Development and Programming pathway, at University Campus North Lincolnshire. I expect to finish in May 2027 and am looking for full-time work from June 2027.

I’m interested in software development and forward deployed engineering or AI solutions roles where I can combine technical work with explaining systems and helping people use them.

I’m also open to thoughtful collaborations on software and developer tools.
