I create systems people want to use, not just tolerate.

I’m Olga, a Product Designer based in Amsterdam.

Over the past decade, I’ve turned complex, frustrating systems into intuitive products that people enjoy using — bringing calm to busy environments and giving people the confidence to do their jobs well.

My work

From POS systems and retail operations tools to logistics dashboards and enterprise software, I design products for environments where speed, clarity, and trust matter.

I’ve built products that cut training time by 40%, reduced operational errors by over 70%, and increased sales by 50%. Many of them are still in use years later, quietly making everyday work simpler for the people who use them every day.

Beyond Work

Design is a huge part of my life, but outside of work, I'm constantly making, exploring, and experimenting.

Work shapes how I think. Everything else shapes who I am.

That's a good sign.
