Interactive Play is the one-man freelance studio of Wouter Verweirder, building interactive installations, games, websites and mobile apps where creative technology meets clean engineering.

## About

Hi, I'm Wouter — a freelance creative technologist.

Interactive Play is my one-man studio. I help agencies, broadcasters and brands bring playful, technically demanding ideas to life — from motion-controlled games on a live TV set to real estate platforms and mobile apps.

I move comfortably across the stack: real-time graphics and sensors, front-end and back-end web, and native-feeling mobile. I care about work that feels effortless to the people using it and is solid under the hood.

- **20+** years building interactive work
- **Solo** — freelance & flexible to your team
