ABOUT ME

I’m a Melbourne-based software developer who likes turning messy business processes into useful, maintainable software. I work across APIs, databases and frontend UI, and enjoy getting feedback from the people who use what I build.

  • C#, .NET, ASP.NET Core, SQL Server
  • React, TypeScript, Svelte, Tailwind CSS
  • Python, REST APIs, AWS, Docker

Engineering workflow

AI-native development

I use AI agents across problem exploration, prototyping and implementation. I combine community-built skills with private, project-specific skills and workflows of my own, with clear constraints, tests and human review guiding the work.

  • OpenAI
  • Claude
  • Cursor
  • Pi agent harness

Community skills

I adapt community-built skills and workflows, adding the context and constraints each project needs.

Custom agent skills

Private implementation

I build reusable skills for project-specific workflows, so agents can work with the right context instead of starting from scratch.

Verification & review

I use tests and code review to check changes, and I’m developing verification skills that help agents inspect results, correct failures and repeat checks.

Agent skills are reusable instructions and supporting tools for specific tasks.

I remain responsible for product decisions, code quality and what ships.
