The Strategic Objectives Achieved
Led a global UX transformation of JackpotFill — modernising a legacy system used by 90%+ of casinos worldwide and cutting jackpot processing time by 40%. The platform was elevated from an outdated WinForms desktop application to a scalable, accessible, web-first product aligned to enterprise UX standards.
Situation & Challenges
The legacy jackpot processing app was an outdated WinForms system with cluttered screens and complex workflows. It was slow, error-prone, and difficult to use or train on — offering little guidance while struggling to meet evolving regulatory demands in high-stakes casino environments.
-
Navigating Regulatory Complexity
Ensuring every workflow and interface met strict, evolving casino regulations while maintaining full usability and compliance across multiple jurisdictions.
-
Untangling Legacy Workflows
Simplifying convoluted, multi-step processes inherited from the WinForms system — which were error-prone and difficult for operators to navigate reliably under pressure.
-
Balancing Usability with Security
Designing intuitive, accessible interfaces that accelerated task completion without compromising on security or strict compliance requirements.
-
Driving Adoption Across Diverse Users
Creating an experience that worked for a wide range of casino staff — from seasoned operators to new hires — minimising training time and resistance to change.
From Legacy to Modern
The transformation replaced a dense, confusing WinForms desktop application with a clean, task-focused, mobile-ready web platform built to scale across the enterprise.
Before — Legacy WinForms
After — Modern Web Platform
User Journey Workshop
I led an in-person discovery workshop in Las Vegas, conducting deep user research and journey mapping to identify pain points and regulatory challenges at their source. Working directly with product, engineering, and compliance teams ensured solutions were both innovative and fully compliant.
By simplifying complex workflows and reimagining user journeys, the research produced measurable improvements in operational efficiency, staff satisfaction, and error reduction.
How I Led the Transformation
Every design decision was grounded in research insight, regulatory constraint, and engineering feasibility. I owned end-to-end strategy and execution across all workstreams.
-
End-to-End UX Ownership
Led the full transformation from legacy WinForms to modern web platform — owning all key design decisions, stakeholder alignment, and delivery milestones.
-
In-Depth Research & Journey Mapping
Conducted on-site user research and facilitated workshops to identify workflow pain points and regulatory challenges at their source — informing every design decision made downstream.
-
Simplified, Task-Based Workflows
Removed interface clutter and restructured flows around discrete tasks — dramatically reducing errors, cognitive load, and time-to-complete for all operator types.
-
Mobile-Ready, Responsive Design
Built for responsive use across devices — enabling casino staff to access the system on the casino floor without being tethered to a fixed terminal.
-
Scalable Design System
Architected a reusable component library ensuring consistent, intuitive UI across all product surfaces — ready to support white-label needs across future markets.
-
Built-In Accessibility (WCAG 2.1 AA)
Accessibility was a first-class design requirement from day one — not retrofitted. Every component was tested for contrast, keyboard navigation, and screen reader compatibility.
-
Lean, Sprint-Based Iterations
Worked in short, focused sprints with tight feedback loops between design, QA, and engineering — maintaining velocity and quality simultaneously.
-
Stakeholder Buy-In via Prototypes
Showcased interactive high-fidelity prototypes to secure executive alignment — including a live product demonstration at the G2E industry conference.
-
Team Mentorship & Leadership
Mentored and empowered a lean, high-performing UX team — cultivating business-aligned, user-centric thinking across every individual contributor on the project.
Final Design Screens
The redesigned platform delivered a clean, regulation-compliant experience across desktop, tablet, and mobile — replacing every legacy WinForms screen with task-optimised, accessible interfaces.
Results & Impact
The redesigned JackpotFill platform delivered a modern, intuitive, and regulation-compliant experience trusted across the casino industry. By replacing the legacy WinForms system with a scalable web platform, the transformation significantly improved usability, processing speed, and accuracy in high-pressure casino environments. The success positioned the new platform as a blueprint for UX excellence across Aristocrat's broader ecosystem.
