FAQ

Which tools do you use?

Figma sits at the centre: screens, prototypes and design systems. Hand-off is prepared so developers can use it directly.

Which industries have you worked in?

Mostly fintech (Paribu, Portföy), e-commerce (Teknosa, SneaksUp, Can Yayınları), insurance (AgeSa) and SaaS.

Can you redesign our existing product?

Yes. I start by reviewing current flows and data, then begin with the screens that will create the most value.

Do you work remotely?

Yes. I'm based in Istanbul and work remotely with teams in Turkey and abroad.
