Designer for bold, ambitious products and teams.
Looking for my next full-time role
I'm a product designer who helps ambitious teams ship bold products without compromising quality.
Eight years embedded with cross-functional teams across gaming, fintech, consumer apps, and government digital services. Design's my craft, but the work is collaborative — I partner with PMs to shape scope, engineers to keep specs honest, and researchers to make sure we're solving the right problem.
How I work alongside a team:
- Shape strategy with PMs and engineering, without drowning anyone in docs.
- Build high-fidelity prototypes the whole team can react to.
- Sit shoulder-to-shoulder with engineering so specs stay honest.
- Co-author design systems the team can keep extending.

Approach
01
Understand before designing.Workshops, interviews, and LUMA facilitation to frame the real problem with the team and build empathy before any screen gets made. The right question beats the right answer.
02
Shape what gets built, together.Scope initiatives, write user stories, and align stakeholders so PMs, engineers, and design land on the same direction. Decisions hold when everyone agrees on what's being built and why.
03
Make things to think with.A working prototype ends debates that a hundred frames can't. Build to learn alongside the team, not to present at them.
04
Sit next to engineering.Pair with devs, write enough frontend to keep specs honest, and hand off what's actually buildable.
05
Leave more than screens.Tokens, components, and patterns the team can keep building on long after I've moved on.
06
Share as we go.Loom walkthroughs, Figma comments, preview deploys. No surprise reveals at the end of the sprint.

In their words
Kosta is a fast, efficient, thorough operator and a pleasure to work with. Over 12 months I've found him to be an excellent designer, continuously going above and beyond expectations. Dedicated, passionate, deeply knowledgeable, creative, and often provides the kind of constructive feedback that lifts the whole product suite.
Kosta brings industry rigour into the classroom. His students leave with a sharper eye and a clearer sense of what it actually takes to ship design work that matters.
As our Lead Designer, Kosta was the quiet engine behind a lot of what made PLAYA3ULL feel like a real product. Strategic when we needed strategy, fast when we needed pixels, and always raising the bar on everyone else.
Kosta takes fuzzy, ambitious briefs and turns them into something we can actually ship. He cares about the craft, moves quickly, and isn't precious about his work. A rare combination in a designer.
One of the strongest product designers I've had on my team. Kosta pairs sharp visual judgement with real product thinking, and he's generous with both. The work around him got better because of it.
