About

I like the complicated, unglamorous parts of software, and making them easy to use.

I'm a Lead UX Designer at HERE Technologies in Berlin. I work where regulation, dense data and human judgment meet in B2B software: logistics, location, AI tools, billing and compliance.

I studied industrial design in Istanbul and service design in Milan before moving into product, and that mix still shapes how I work. I look at the whole service around a screen: who's involved, what happens behind the scenes, and where things break. At HERE, a single problem often involves an AI model, a billing system, a support team and a customer's invoice. Before HERE, I worked at Spark Networks, Bosch, IBM and Biletix (Ticketmaster).

Some recent results I'm proud of. Each one started with the team agreeing on a smaller, sharper problem.

Outside work, Pilates and weight training keep my head clear. I travel as often as I can, mostly to see how other cultures eat, dress and decorate their homes. I'm a committed foodie, I notice interior and fashion design everywhere, and I spend more time in galleries than is strictly reasonable. A lot of my taste in product work comes from that world away from screens.
