Ethical bank account
Mobile application
Summary
As a lead UX/UI, I accompanied the Swiss startup Mizen in the design of its mobile banking application. The goal was to provide a smooth and reassuring experience despite the complex legal constraints of banking onboarding. I defined the entire user experience, designed the design system, and ensured the coherence of the interface in close collaboration with the developers.
Context
Product : Personal banking management mobile application
Company : Mizen (fintech startup based in Geneva)
Target users : New clients looking for a simple and digital banking solution
Challenges :
Create a smooth onboarding experience despite regulatory steps
Structure the entire interface with a clear design system
Work 100% remotely with the technical team
Problems to solve
Onboarding too long or anxiety-inducing due to identity verification steps
Lack of clear hierarchy between main features
Risk of poor implementation without a formalized design system
Methodology
Research and Inspiration :
Benchmark of neo-bank apps (Revolut, N26…)
Decoding regulated pathways (KYC)
Ideation and Prototyping :
Redesign of the registration process to make it progressive and educational
Creation of a design system based on Material Design
Complete prototype on Figma for qualitative user testing
Collaboration & Tools :
Remote work with the product and dev team (CEO, developer, QA)
Figma for design and prototypes
Sharing components for smooth integration in React Native
Testing and Iterations :
Testing the onboarding process with users in a frozen version
Taking feedback into account to adjust messages, visuals, and sequences
Results & Impact
Deliverables :
Complete high-fidelity prototype of the application
Documented design system ready for development
Impact :
More engaging and less anxiety-inducing user journey
Reduction of implementation error risk
Feedback :
An enriching project that allowed me to lead an end-to-end design, from UX strategy to technical integration, in a 100% remote context.
