Selected systems work

Building clearer, more reliable ways of working.

I work across internal tools, workflow improvement, automation, and validation—especially where a real process is fragile, repetitive, or difficult to maintain.

About

I have a development background and a verification habit: I learn how a real process works, find where it fails, and turn that into tools, tests, or automation that can be trusted in production—not only something that runs once.

That mix has shown up in hospital systems programming, enterprise RPA quality work at KPMG Canada, and independent full-stack builds. I value solutions that are not only functional, but understandable, testable, and maintainable by the people who rely on them.
