hi, i’m koray
Product designer who ships fast and breaks things (intentionally).
I design products and build the front-end that ships them. I’m at my best in the gap between Figma and production, working close to research and close to the code. I write here about what I learn along the way.
now
Designing Accountable, a tax and accounting platform for freelancers. The job is making taxes feel a little less like taxes.
On the side: rebuilding this site by hand, and learning to write in public.

selected work
Fantium
A web3 platform where fans invest directly in athletes through tokenized ownership of their future earnings.
Led product on a simpler wallet and checkout, then shipped loyalty, payments and analytics over 12 months.
Empower Parenthood
A parenting platform that reduces stress through community-driven support and smart resource discovery.
8 in-depth parent interviews shaped a hub-and-spoke app, with a Playground Discovery system as its flagship feature.
Self-Driven Learning
A peer-to-peer learning platform that helps adults teach and learn from each other.
Research with 12 adult learners led to an "Adaptive Autonomy" model and Peer-2, a platform where everyone is both teacher and student.
Datanator
An interactive art installation about data privacy. A dark room full of screens that watches you back, built to make people feel what happens to their data.
A 5-person team turned a campus room into a one-day exhibition, using Kinect tracking, live camera feeds, sound-reactive graphics and a blackout, for CODE students, staff and Factory Berlin members.

- 06Data-driven decisionsLet behaviour settle the argument.
Have a product that needs shape?
I take on a few freelance projects at a time: product design, UX research and design engineering for early-stage teams. Expect research-backed decisions, quick prototypes, and designs that survive contact with the codebase.
