I am a developer of apps, libraries and algorithms that improve athletic health and performance. When I am not developing, I might be cycling, running or XC skiing. I am Dutch-born, but now embracing Norwegian life with my family.

Working with me

I support sports tech startups in building their first application. My combined background in sports science and software engineering accelerates development and reduces time to market: I am the engineer that actually understands your domain. For these clients I also develop specialized tools and applications.

My tools and services are also used by sport data scientists and researchers, giving them quick access to data and algorithms and removing the technical overhead of their work.

As a sports scientist, my main fields of expertise are athlete (metabolic) profiling and training load monitoring in endurance sports. As a software engineer, my main fields of expertise are platform integrations, data standardization and data storage at scale.

Applications:

• Sweat Stack: A sport data analytics platform for developers and data scientists.
• WorkoutGPT: An application that creates structured workout files (like Zwift .zwo files) from workout descriptions in natural language.
• Paper Playgrounds: An interactive tool that transforms academic papers into hands-on experiences by making them interactive and/or based on your own data.

Services:

• Sports data engineering services: Anything from building applications from the ground up to domain specific support for existing development teams.
• Sports data science services: Independent data science solutions from start to finish but also assisting existing data science teams.
• Fractional CTO services: Strategic technology leadership and innovative solutions for early-stage sports tech startups.

Previous clients include:

• Entalpi: A Norwegian-based startup, founded by Olav Aleksander Bu.
• Humango: A US-based startup developing AI training technology.
• INEOS Grenadiers: One of the best professional cycling teams, based in the UK.
• Sport Data Valley: A Dutch government funded sports data analysis platform.

My daily tech stack is centered around Python but I am familiar with a wide range of languages and platforms.
