Platforms Refresh was a multi-product redesign initiative aimed at modernizing legacy trading platforms and establishing a consistent user experience across the StoneX trading platforms, addressing fragmented interfaces, outdated visual standards and inconsistent interaction patterns across multiple products.

My Role

Led interface redesign across several legacy trading platforms.

Designed key product flows and complex trading interfaces.

Established consistent UI patterns across fragmented products.

Introduced iterative collaboration between design, engineering and QA.

Results

Improved usability and visual consistency across multiple legacy platforms.

Reduced interface fragmentation through shared UI patterns.

Accelerated implementation by aligning design and engineering workflows.

Improved implementation quality through closer collaboration with dev and QA.

Established UI foundations later used in the MyStoneX design system.

The goal of Platforms Refresh was not to redesign a single product, but to gradually improve visual consistency and usability across several existing trading platforms.

Rather than introducing a completely new system, the work focused on stabilizing core interface patterns and aligning visual behaviors across products that had previously evolved independently.

This included:

  • Redesigning key platform screens to improve clarity and modernize visual structure
  • Aligning navigation and layout patterns across multiple products
  • Standardizing core interface components such as tables, filters and data displays
  • Introducing more consistent interaction behaviors for common workflows

Interface Improvements

The refresh focused on improving clarity, consistency and usability across several key platform interfaces. Rather than redesigning products from scratch, the work prioritized stabilizing core workflows and modernizing critical screens used daily by traders.

The improvements focused on several areas:

  • Trading interfaces - simplified visual structure for complex data-heavy environments
  • Data tables and monitoring views - improved readability and interaction patterns for positions, orders and market data
  • Navigation patterns - more consistent structure across platform sections and products

Improving legacy platforms required close collaboration between design, engineering and QA teams. Because many systems had evolved independently, interface decisions often needed to be validated against existing technical constraints and platform architecture.

Instead of working in long design phases, the process relied on frequent reviews with developers and quick iterations on complex trading interfaces. This helped align visual improvements with real implementation possibilities while reducing friction during development and testing.

Working sessions helped surface inconsistencies & technical limitations early, allowing design decisions to gradually stabilize shared interface behaviors across multiple platforms.

Platforms Refresh helped stabilize the visual and interaction layer across several legacy trading platforms while improving overall usability and consistency.

By aligning interface patterns and modernizing key screens, the project reduced fragmentation between products and made platform workflows clearer for both users and development teams. The work also highlighted the need for stronger system thinking across the product ecosystem, which later informed early explorations around building a more structured design foundation.

Impact

PRODUCT CONSISTENCY

Unified interface components & UX patterns reduced fragmentation across multiple trading platforms.

WORKFLOW CLARITY

Simplified complex trading screens, making core workflows easier to navigate.

DESIGN–ENGINEERING ALIGNMENT

Closer collaboration with engineering decreased implementation times and improved consistency .

STRUCTURED DELIVERY

Parallel product streams operated within a shared architectural framework across web and mobile.

SYSTEM FOUNDATIONS

Early system thinking laid groundwork for scalable design infrastructure across products.
