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 am an independent developer and consultant working on the intersection of data engineering and sports data science. As a sports scientist, my main fields of expertise are athlete profiling and training load monitoring in endurance sports. As a data engineer, my main expertises are data storage at scale, platform integrations and data standardization.

Applications:

• Sweat Stack (in beta): A sport data analytics platform for developers and data scientists.
• WorkoutGPT (in beta): An application that creates structured workout files (like Zwift .zwo files) from workout descriptions in natural language.

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 startups in the sports domain to help them reach product-market fit.

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.

If you are interested in working with me you can contact me at aart[at]gssns.io (not that bots these days don’t know how to make an email address out of that 🤷). You can also find me at LinkedIn, Twitter, BlueSky (not that active there yet) and Strava.
