The original mobile experience had grown fragmented over time. Advanced traders wanted faster access to pro-level tools, while beginners found the interface intimidating and difficult to navigate. Maintaining two separate apps also increased development overhead and introduced UX inconsistencies.

Our goals were clear:

• Create a clear entry point for new users to easily buy crypto without trading knowledge.
• Deliver a powerful, efficient experience for advanced traders.
• Build a scalable design foundation that could support both audiences within one app.
• Improve conversion, retention, and brand perception through consistent, modern UX.

To deeply understand both audiences, we conducted competitor analysis, user interviews, and usability testing with existing Bitstamp users and potential newcomers.

Key insights included:

• Simplicity drives confidence: New users needed guided flows, plain language, and clear visual hierarchy.
• Speed and control matter: Experienced traders valued access to more complex data, precision, and minimal friction.
• Consistency builds trust: Visual and behavioral differences between Basic and Pro experiences caused confusion.

These findings helped define the product vision, that were two tailored experiences built on one shared design system and architecture.

I led the full design lifecycle, from discovery workshops to final developer handoffs:

1. Ideation & Concepting: Facilitated collaborative sessions with PMs and developers using Figma to generate multiple flow concepts.
2. Wireframing & Prototyping: Designed rapid prototypes for early validation and alignment with business goals.
3. Usability Testing: Conducted iterative testing sessions to refine onboarding, trading, and portfolio flows.
4. Design Delivery: Created pixel-perfect, developer-ready designs and ensured cross-platform consistency (iOS and Android).

Throughout the process, I collaborated daily with developers via Jira, ensuring design intent was preserved in implementation. I also introduced design tokens and component guidelines as part of the Bitstamp Design System, which became the backbone of all mobile products.
