Mobile and backend delivery.

Boxbollen connects a training ball to a mobile app for games, training and competitions. Features such as chat, tournaments and promoted content span the app, backend services and admin tools.

I owned delivery across the Flutter app, backend, data, APIs, admin tools, CI/CD and test automation. I worked on product features and the systems needed to operate and release them.

I built global and direct chat with message requests, reactions, read receipts, typing indicators and moderation. I delivered battles and tournaments, plus a promoted-content system with campaign settings and performance tracking. I also built native FFmpeg libraries for local media processing and updated Android libraries for the 16 KB page-size requirement.
