Hi, I'm Gintaras, I’ve helped businesses across the US, Netherlands, Norway, Germany, UK, and Lithuania turn UX into a competitive advantage in retail, healthcare, telco, adtech, finance, and insurance. I design and scale products on SAP Commerce (Spartacus), Salesforce, and WordPress, making sure every decision leads to measurable business impact.

I hold a Master’s in IT and Management from Illinois Tech and an MBA from ISM University. My work on Adform Flow earned Red Dot and IF Design Awards, proving that great UX isn’t just about aesthetics, but it drives results.
