MuseScore

Product Design Lead. 2023 – now

Global rebranding

Joined a small working group collaborating with COLLINS on creating a new brand from the product side.


A year later, helped bring it to life across real product interfaces — rebranding not just how it looks, but how it works. Generated a full set of branded UI artifacts, built a cohesive animation language, and coordinated efforts across design, product, and design system teams to make it all happen. Big respect to everyone involved <3

Strategic goals

Created a product design strategy aligned with Muse's global goals. Defined and defended the design team’s organizational structure. Managed stakeholders to make design system happen — from the ground up to full coverage.


Established ongoing processes for managing design debt, driving local redesigns, and shaping the product vision.

Team management

Work with a small but exceptionally effective team of talented designers. Hire, let go, host workshops, and continuously focus on strengthening the team.

Product growth

Work closely with the Head of Growth to design and launch A/B experiments aimed at scaling the product. Focus on improving key metrics such as Time spent, D7 retention, and Registration rate.
