Who I work with

I love working with teams that:

  1. 01

    Are building or growing SaaS platforms, dashboards, fintech products, or operational systems with complex workflows.

  2. 02

    Want a senior designer who owns problems end to end — not just someone waiting to be handed a spec.

  3. 03

    Want a senior designer in the team for the long run, full-time or part-time. I work remotely from the EU, with hours that overlap US and EU teams.

How I work

Fast to onboard. Easy to work with.

  1. 1 / 3

    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. 2 / 3

    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. 3 / 3

    Broad experience, applied to your problem

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

About

I own the work end to end — no hand-off, no delegation.

Senior Product Designer · Based in Europe · 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 me.

Book a call and see if it's a fit

20 minutes, no pitch. I'll tell you honestly if I'm the right fit for what you're building.

If you're building complex AI apps and the design isn't where it should be, a 20-min talk is a good place to start.

I think about the product strategically, catch issues before they ship, and hold the work to a high bar without needing hand-holding. I'm open to full-time or part-time roles, as an employee or on a long-term contract, working remotely from Vilnius with US and EU teams.
