My professional experience is split between 6 years as a founder & CTO of three companies, and working on designing and prototyping TV experiences at a design agency.

As the CTO of Betuned, I am in charge of rebuilding their WordPress website using Nuxt 3, Tailwind and Sanity to improve its performance and make it easier to update.

As CTO, I developed a B2B SaaS product that enables creating and hosting Web Stories. The front-end is built with Vue 3, the back-end uses Google Cloud Run and Cloudflare Workers. Our hosting infrastructure delivered over 15 million Stories, with no downtime. I managed two junior software developers, including one remotely.

Overview was the beginning of my entrepreneurship journey. I developed an Android app that parsed Kenyan mobile money SMS messages to visualize transactions and help budget finances. I built and launched a v1 with Java, and a v2 with Kotlin. Machine learning was used to try to create predictive budgeting models.

I led the Red Bull TV project for the design agency Edenspiekermann. With my team of 10+ people, a comprehensive design system was created, ensuring consistency across platforms. Prototyping played a huge part in getting the feel for the TV apps just right, leading to winning the Google Play Award for best TV experience in 2017.


As a technical founder, my skills are extremely broad, but focus on delivering digital products and experiences as efficiently as possible, without compromising on quality. My speciality lies in Jamstack serverless applications.

Personal interests

Educating myself on issues like mobility, the energy transition and social justice keep me thinking and acting. During the pandemic I taught refugees to code at Hack Your Future.

I also enjoy riding my ebike, playing board games and cooking spicy food for my friends.
