About the Project

We’re collaborating with an innovative health-tech startup that’s developing an AI-powered motion analysis platform. Using computer vision and biomechanics algorithms, the system processes videos to deliver detailed motion data and automated reports for clinicians, therapists, and sports professionals.

 

The product includes a web dashboard that visualizes 3D movement data and integrates with cloud services, and you will work on the redesign of this dashboard.

You’ll join the project during an active development phase — working closely with the client’s technical team and PLANEKS engineers. Communication is via Slack, with occasional sync calls for design discussions and demos. The client is based in Europe.
