Gintaras Lukoševičius

Technology move fast.
People don’t. Focus on humans.

Technology move fast.
People don’t.
Focus on humans.

Hey, I’m Gintaras. I help teams build digital products that make sense to real people, in real situations, with real stakes.

Over the last 10+ years, I’ve worked with Fortune 500s, fast-growing startups, and everything in between, from Philips or Tax-free.no e‑commerce to Software as a Service for REHAU, enterprise tools for Medtronic and Adform or self-service platform for Telia.

I’ve led redesigns that moved the needle. Like turning a clunky enterprise platform into a 197% jump in revenue per user. Or helping teams move faster by building design systems that scale without losing clarity.

My background? IT + MBA. My edge? I speak business and design fluently and I don’t waste time on fluff.

If you’re building something complex, and you need someone to make it feel simple — let’s talk.
