About

Background

I began in audiovisual production and moved into UX and product design in 2018. Working in small teams brought me into product ownership: understanding workflows, setting priorities, writing user stories and following releases.

The MSc and the R&D work added building and evaluating technical tools. That combination lets me connect interface decisions with the software and data behind them.
