The Strategic Objectives Achieved
Led a global UX transformation of JackpotFill—modernizing a legacy system used by 90%+ of casinos and cutting jackpot processing time by 40%.
Elevated product from legacy WinForms to scalable, accessible, web-first platform 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The legacy jackpot processing app was an outdated WinForms system with cluttered screens and complex workflows.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 usability and compliance
Untangling Legacy Workflows: Simplifying convoluted, multi-step processes inherited from the outdated WinForms system, which were error-prone and difficult for users to navigate.
Balancing Usability with Security: Designing intuitive, accessible interfaces that accelerated task completion without compromising on security or compliance requirements
Driving Adoption Across Diverse Users: Creating a user experience that worked seamlessly for a wide range of casino staff, from seasoned operators to new hires, minimizing training time and resistance to change
Our Journey
From here
To here
User Journey Workshop
I led a discovery workshop in Las-vegas to conducted deep user research and journey mapping to identify pain points and regulatory challenges, and collaborated directly with product, engineering, and compliance teams to ensure our solutions were both innovative and fully compliant.
I simplified complex workflows and reimagined user journeys, resulting in measurable improvements in operational efficiency, staff satisfaction, and error reduction.
Key Decisions & Rationale
I Led end-to-end UX transformation of legacy WinForms jackpot processing app into a modern, web-based platform and owned all key decisions.
Conducted in-depth user research and journey mapping to identify workflow pain points and regulatory challenges.
Collaborated closely with product, engineering, and compliance teams to ensure all design solutions met strict industry regulations and seamless integration needs.
Simplified Workflows: We removed clutter and focused on task-based flows to reduce errors and training time.
Mobile-Ready Design: Built for responsive use, making it easier for staff to access the system on the go. Moved to iteration 2
Built a scalable design system for consistent, intuitive UI across platforms.
Built-In Accessibility: Designed to meet WCAG 2.1 AA standards from the start—no retrofitting needed.
Lean, Fast Iterations: We worked in short, focused sprints with quick feedback loops to stay on track.
QA + Design Sync: Regular design validations with QA ensured nothing slipped through the cracks.
Showcased interactive prototypes to secure stakeholder buy-in, including at G2E.
Mentored and empowered a lean, high-performing UX team to deliver business-aligned, user-centric outcomes.
Outcome
The redesigned JackpotFill and TM applications delivered a modern, intuitive, and regulation-compliant experience trusted by various customers By replacing a legacy WinForms system with a scalable, web-based platform, we significantly improved usability, speed, and accuracy in high-pressure casino environments.
Key results include:
Faster workflows with simplified UI, reducing average processing time by 30–40%.
Higher user satisfaction, thanks to streamlined journeys and accessibility built into the core design.
Improved adoption and confidence among casino staff with reduced training time and fewer errors.
Stronger stakeholder alignment, driven by early prototypes, design walkthroughs, and G2E showcases.
A scalable design system ready to support future features and white-label needs across markets.
The success of this transformation not only enhanced operations on the casino floor but also positioned the new platform as a blueprint for UX excellence across Aristocrat’s ecosystem.
