Own work

Nine products under my own name

Conceived, designed, built, shipped to the store and maintained by me. Not commissions, but own products with real users.

They are not here to impress with numbers. They are here because they show what actually comes out of this studio: an idea taken all the way, including the store page, the landing site and the maintenance after. That is exactly what a commission gets too.

Practice and exams

Apps for people facing a test or exam. Short sessions, an exam mode, an explanation per question, and a marketing site per market.

VCA Oefenen

Practice for the Dutch VCA safety exams

Practice app for the Dutch VCA safety exam, with mock exams and mistake training. The audience in construction, engineering and staffing is often not Dutch speaking, so the site runs in five languages.

Five practice apps, five audiences. A construction worker taking a safety exam needs a different app than a nursing student, and you can see that in the design. The design follows the audience, not a house style.

Tools

Software that came out of the work itself. When a task returns often enough and the existing tooling falls short, I build it myself.

MediaText Studio

Subtitling and timed text on the Mac

Native macOS app for subtitling: spotting on the waveform, video reference, conversion between timed text formats, quality control and delivery exports. Built out of the audio post work, for production companies, editors, subtitlers and localisation teams.

DienstBrein

In development

External working memory for a care shift

Note something in two seconds, tick it off when it is done, and at the end of the shift the handover is ready. Works with four coloured pens: three for tasks, one for notes that always carry over to a colleague. No account, no server, no ads. The prototype is being tested by care workers.

The MediaText Studio Subtitle Editor: a cue table showing timecode in and out, duration, and characters per second and per line for each cue, with a retiming and frame rate conversion panel on the right.
The cue table in MediaText Studio. Characters per second and per line are counted per cue, because that is what subtitles actually get rejected on.

Own initiative

Projects that exist because as far as I am concerned they had to, not because there was a business model underneath.
