About

Current

Solo founder and engineer of GemKa: three live products, all launched in August 2026.

GemTimer is the timer I use every day. I track what projects I work on and how much deep work I do.

GemTodo is my way of doing to-do lists, iterated on for nine years. Every todo goes to a project and into Action, Someday or Reference.

IdeaKache is a collection of ideas gathered from books, podcasts, X and corners of the internet. Every one of them has taught me something.

Everything I've learnt in 2026 is from getting started: single sign-on across the products, a shared design system published as a package, staged releases, nightly automated tests and off-site backups proven by restore drills.

Before that

Ten years at McKinsey focusing on enterprise-wide Transformations across technology, financial services, retail, industrials and natural resources companies. Drove new outside-in diligence offering using AI. Learned what excellence looks like.

The rest

Started as a solicitor at Mallesons in Perth, Australia. CFA charterholder since 2022. High proficiency in building LBOs and financial models.
