Hi, I'm Mert.

I design digital products that simplify complexity.

Welcome! You won’t find any art here—just experiments, anxieties, stakeholders, failures, and learnings.

Focused on fintech, crypto, and education with a user-first and business-aware mindset.

My experience

20 Products

Impacting 30M+ users

Over the past decade, I’ve designed and shipped 20+ digital products used by more than 30 million people. From startups to enterprise-scale platforms, my focus has always been the same: solving real problems through thoughtful, user-centered design without forgetting about the business.

30 Workshops

From classrooms to C-suites

Since my university years, I’ve been organizing and running workshops on UX Strategy and Design Thinking. From students to senior stakeholders, I’ve helped teams unlock better ideas, align around goals, and prototype smarter solutions fast.

I have worked with many designers throughout my journey, but my collaboration with Mert was a unique encounter that still stands out to this day. His equally broad and deep knowledge around product and UX paired with his ability to articulate design decisions convincingly to stakeholders was an invaluable asset to our team and made a lasting improvement on our ability to execute more confidently and with bigger business impact. Mert is a standout designer and would become an appreciated member of any product team.

His resolution and his ability to looking from different perspectives make him a very successful problem solver, and these are just a few of his high range skills. He has the motivational leadership ability, decision-making, and communication skills that a team member needs for success. I could always depend on him to set the best example as a Product Designer at KWORKS. He absolutely shines in a hectic environment. Definitely worth recommending.
