02What I work with now

Core skills

These are the five top skills on my LinkedIn profile. Each one shows the latest roles, projects or labs where I used it, with links, so you can check the work behind it.

In active use

I have used these 88 skills in a role, a project or a coursework lab in the last 18 months, since Apr 2025. The most recent come first, then the ones I used in more places. Each one shows where I last used it, and opens its row in the atlas. A year on its own means the record has no month, as with the coursework labs, which carry only the year I rebuilt them. Dates are as of 10 Oct 2026.
