The Challenge
SweepBank, a digital banking brand under Multitude, aimed to disrupt traditional banking with a fully mobile experience. But with a lean team and tight timeline, we faced key challenges:
High drop-off rates in onboarding
Fragmented user flows and inconsistent UI
Lack of foundational design systems or clear product vision
My Role
As the Lead Product Designer, I partnered closely with the CPO and cross-functional squads. I steered design efforts from initial discovery to final delivery — ensuring we met aggressive business goals without compromising usability.
Our Strategy
Rapid Discovery & Alignment
Conducted stakeholder interviews to align on KPIs and business goals
Audited competitive mobile banking experiences across Europe.
2. Lean Prototyping & Validation
Created mid-fidelity prototypes to test key flows (onboarding, dashboard, transactions)
Ran usability tests with target users to validate and iterate quickly
3. Design System & Scalability
Established a foundation component library and UI guidelines
Enable faster handoffs and ensured consistency across native platforms (iOS & Android)
4. Close Collaboration with Dev & Product
Worked in 2-week sprints embedded in squads
Provided specs, edge-case documentation, and accessibility guidance
Results
Onboarding completion rate doubled within 3 months post-launch
Product scaled from MVP to full-featured banking app used across several EU countries
Created a design culture that outlasted my tenure and continued to support new product lines
