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.
