INTRO

A short story

A quick intro

I graduated from DTU in 2022 with an M.Sc. in Computer Science & Engineering, and I’ve studied abroad at Politecnico di Milano and the University of British Columbia.

I enjoy building products from scratch and taking them all the way to production—frontend, backend, and the glue in between.

I build mobile apps with Expo/React Native, and I’ve shipped web applications for years using React/Next.js, Node.js, and GraphQL through my work at DBC Digital. Mostly working with bibliotek.dk and fbi-api.dbc.dk.
