A small hello from Barcelona

Hey, I'm Sami.

I'm a product manager who started out as a software developer. Today I lead the teams behind Registration and Check-In at Webex Events.

Before that, I spent five years at Turkcell, where the fizy app grew past two million monthly users and Dergilik learned to read aloud. At Türk Telekom, we relaunched a music app as Muud in three months.

I've never found a magic formula for products, only learning fast and improving as we go. Sometimes a little too fast: one morning during the Muud relaunch, I went to work in one red shoe and one black.
