Designing AI and SaaS products since 2017

I love working with teams that:

Are building or growing a SaaS platforms, dashboards, fintech products, or operational systems with complex workflows.
Wants one senior designer who owns problems end to end — not just someone waiting to be handed a spec.
Are hiring full-time and remote — I'm not relocating, but I'm flexible across time zones.
Let's talk →

Fast to onboard. Easy to work with.

1

I ramp up fast — even on complex products

Years of experience means I don't need weeks to get oriented. I get into the product, the users, and the constraints quickly, so I'm producing real work in the first days, not just asking questions.

2

I adapt to your workflow

I plug into whatever process and tools your team already uses instead of imposing a new system. I over-communicate by default, so you always know what I'm working on and why.

3

Broad experience, applied to your problem

Years working across different teams and industries as a contractor mean I've already seen a wide range of product problems. I bring that experience into whatever you're building instead of starting from zero.

Some of my latest work.

Senior Product Designer  ·  Vilnius, Lithuania  ·  Toptal Top 3% Verified

I've spent 9+ years designing digital products — the last 5 focused on AI-native features, fintech, enterprise platforms, and data-heavy dashboards. Toptal verified me as a top 3% product designer globally, and that's the bar I hold myself to on every project.

I like being close to the work — in Figma, in Slack, in the planning conversations — not just reviewing what lands on my desk after the fact. If you want a senior designer who owns problems end to end instead of waiting to be handed a spec, that's how I work.

Testimonials

From the people we've worked with

★★★★★

I had the pleasure of working with Gytis for a long time, and he has consistently been one of the most thoughtful and dependable product designers I’ve worked with.

Gytis thinks deeply about the product, the user, and the business context behind every design decision. He is very strong at turning ambiguous ideas into clear, polished, usable experiences, and he brings a high level of taste and discipline to the work.

Gytis is someone I could trust with important product problems. He communicates clearly, takes feedback well, and has a calm, mature way of moving projects forward even when the direction is still evolving. That combination of creativity, judgment, and ownership made him a real partner to the product team!

★★★★★

Gytis is deeply professional, dependable, and a real pleasure to work with. I've been working with him as product owner while he leads our UX/UI design, and I've always been able to trust Gytis completely. He finds a way to approach uncertain work analytically and thoroughly, and helps answer the questions we hadn't yet thought to ask. He is a pro at taking the often chaotic, undefined input and getting back to us with results that are logical, structured, and well-argued. I would gladly recommend Gytis to anyone building new, unconventional solutions who needs a steady partner to help them move through the uncertainty with confidence.
