Zeynep Günay Bıyıklıoğlu

Product Designer

I design products that get simpler as they get more capable.

With a background in journalism and visual storytelling, I bring together user empathy, business thinking, and design craft to create meaningful products. I have designed end-to-end digital experiences across fintech, automotive, SaaS, and enterprise platforms, balancing user needs, business objectives, and technical realities. I believe the best design is invisible — it doesn't ask for attention; it simply works.

Design Philosophy

Product thinking before pixels.

I start with a single constraint, not a screen. On Bikadro it was one question — does this feel like Behance, or a listings site? On Port Cüzdan it was a regulation. A clear constraint gives every later decision, from grid density to copy tone, something to be measured against.

I design for failure before I design for success. A blurry ID scan, a phone without NFC, a connection that drops mid-verification — these usually get treated as edge cases. I treat them as the actual brief, because that's where trust is won or lost.

Removing is a decision, not a default.

Remove before you add

I look for what a product doesn't need before I add what it might.

Design the failure state first

The unhappy path — a blurry scan, a dropped connection — gets designed first, not patched in later.

One neutral rule, applied everywhere

A single, consistent decision — like a button color rule — does more for a calm product than a hundred small ones.

Accessible from the first sketch

WCAG isn't a pass at the end; it shapes the flow from the first wireframe.
