Who I work with
I love working with teams that:
- 01
Are building or growing SaaS platforms, dashboards, fintech products, or operational systems with complex workflows.
- 02
Want a senior designer who owns problems end to end — not just someone waiting to be handed a spec.
- 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 / 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 / 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
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.
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.
