An experimental approach to creating cartograms that replace geographic distance with travel time, revealing which places are truly close to each other.
A system designed to track the campus shuttle busses at the University of Minnesota - Twin Cities. Pulls data from the existing NextBus API, cleans and interpolates it, and generates predictions using the scikit-learn machine learning library.
I'm currently available for freelance projects or full-time employment!
I love seeing data projects all the way from idea to execution. My unique experience spanning software development and consulting means I can see all the way from business value to implementation details.
In my latest role, I worked as a Senior Analytics Engineer at TIER Mobility in Berlin, Germany. At TIER, I helped build data products for our partner cities, including Berlin, Paris, and Oslo. One of the projects I'm most proud of is the Bike Lane Analysis, where I combined usage data from our vehicles with Open Street Map data to show cities the gaps in their bike lane networks.
Prior to joining TIER, I was part of the Data & Analytics team at Slalom Consulting. At Slalom, I was a data engineering consultant that worked with digital product teams at a variety of companies.
I have a bachelor's degree from the business school at the University of Minnesota, where I also completed a minor in computer science. For my thesis I analyzed the usage and equity of scooters in the Minneapolis area using geospatial techniques.
When I'm not in front of a computer screen, I enjoy running (check me out on Strava), open-water swimming, and cross-country skiing. I love learning new things and am currently working towards fluency in Norwegian - jeg har en lang vei å gå...
