I'm a 22-year-old industrial design student from Istanbul, Turkey. As a three-time Community Champion, I have had the chance to collaborate with OpenIDEO team in supporting community interactions and helping community members push their ideas forward.
Now, I'm the Community Prototyper for the Healthy Lives challenge and looking forward to collaborate with you!
