About

I am moving into professional software development through independent products, developer tools, and structured learning. I use AI to help implement the work while I set direction, inspect results, test behavior, and own what is presented.

Before moving into software, I served 22 years in the British Army, including 7.5 years at Warrant Officer rank. Standards, instruction, operational delivery, and people leadership still shape how I work.

My earlier career was built around logistics, instruction, standards, and helping people perform under pressure. I now apply those habits to software: make the goal clear, test the actual path, and explain the limits alongside the result.

This portfolio is the public record of that transition: working projects, case studies, technical writing, and the decisions behind them.

Fun Facts

Updated July 2026

British Army

22 years in the British Army

Twenty-two years of service, including 7.5 years at Warrant Officer rank, shape how I lead, teach, and work.

AI workflows

Current

I spend a lot of time testing where agents help, where they drift, and how humans keep hold of the work.

CLI projects

Small tools

I like tiny developer tools that are easy to explain, easy to run, and honest about their limits.

Receipts over hype

Taste

The work I trust most shows its reasoning, its evidence, and the boundary of what it can claim.

Skills

Software development

Turning product goals into small, testable software systems with clear behavior and honest limits.

Technical communication

Explaining technical choices, commands, results, and limitations in language a maintainer can use.

Developer tooling

Designing small command-line and desktop tools with predictable inputs, outputs, and failure paths.

Instruction and standards

Using a military instruction background to make complex technical work executable and inspectable.

    Building on verified leadership and management qualifications up to Level 7 while developing practical software skills through project work.

    My planned study is the UCNL HNC Level 4 Digital Technologies – Software Development & Programming Pathway FT, alongside the Google Project Management and Google Cybersecurity Professional Certificates. These are study intentions, not completed qualifications or a claim of enrollment; dates are not yet confirmed.
