About Jack Kinsella

Current Project

I run Semicolon Berlin GmbH, a software agency that makes cross-platform apps/web-apps. We've done the official apps for national political parties (e.g. FDP in Germany, Open Vld in Belgium), large corporations (e.g. Tuev Nord), and public institutions (e.g. University of Potsdam).

I create programming screencasts showing actual workflows in production codebases using timeless technologies over at Semicolon and Sons.

Past Professional Activities

Immediately after college, I built Oxbridge Notes, an automated niche marketplace for college notes. Although I retain full ownership, I am no longer operationally involved with the business, having delegated management to a dedicated team.

I also co-founded a "real world" organisation, the Bolivian Express, which is now Bolivia's largest English language magazine and has since won the praise of president Evo Morales.

I've written technical books, articles, games, and apps.


Thanks to the modern democratising magic of DAWs and sequencers, even kluxes like myself can write music. My taste is for bittersweet, poignant music, soaked in rich and lingering harmonies. #i-sound-like-a-wanker


Even though I studied law at Oxford, graduating in 2009, I consider my primary background to be in computer science, having engaged with the field for nearly one-and-a-half decades.
