Raiffeisen Bank

Lead Product Designer. 2020 – 2022

Product design

Joined the retail team as a Lead Product Designer to redesign a mobile banking app for 2.4M users with a focus on speed and clarity.


In collaboration between product, research and design teams identified top 10 user flows, benchmarked them against 3 main competitors by time and number of taps. Led a step-by-step redesign to outperform competitors while preserving familiar user habits.

Rebranding and emotional UX

Led emotional product design stream and rebranding efforts for Raiffeisen Bank. Collaborated closely with Design Studio as a product representative to craft the new brand and design strategy.


Spent a year implementing it across all touch points — from design system to interfaces and communications. With love to every detail 👁️

Team leadership

To reach ambitious product goals, I initiated and led a series of design hackathons — turning collective creativity into actionable outcomes for product teams.
