Design System Updates and Enhancements.

With Epsilon marketing solutions, you can engage consumers through personalized, measurable interactions that enhance performance.

My Role

At Epsilon, I worked on a wide range of projects, from evolving the design system to building out custom UI for desktop apps across the PeopleCloud suite. I helped modernize and expand the system so it stayed easy to use and aligned with today’s standards. Along the way, we created experiences that made the platform more cohesive and engaging for users.

Key Contributions

  • Helped modernize and expand the design system to meet evolving product needs, accessibility standards, and modern UI patterns
  • Cleaned up components by fixing inconsistencies and improving usability
  • Collaborated across teams to identify gaps, leading to new scalable components
  • Streamlined naming conventions and improved Sketch organization for a more intuitive system.
  • Worked closely with engineers and product to ensure updates were doable and implemented smoothly
  • Improved onboarding and guidance to make the system easier for designers at all levels

Custom UI Experiences.

At Epsilon, I designed custom UI that balanced brand needs with system consistency, adapting components or creating new patterns to deliver intuitive, scalable experiences.

Contributions

  • Designed and fine-tuned desktop interfaces across the PeopleCloud suite, helping keep things consistent and connected across products
  • Built custom UI solutions that met each product’s needs while staying true to the design system
  • Worked closely with PMs and engineers to turn complicated ideas into clear, user-friendly experiences
  • Helped bring more alignment across products making sure everything looked, felt, and worked like part of the same platform
  • Focused on usability and visual polish to make the experience smoother and more engaging
  • Balanced consistency with flexibility creating reusable patterns while leaving room for customization where it made sense

Designing for Flexibility and Cohesion

Custom UI experiences were designed to balance flexibility for unique product needs with cohesive, system-wide consistency across the platform.

Overcoming Challenges

Handling Ambiguity

When I joined Epsilon, there was already a plan to improve the design system. When teams weren’t sure what they wanted, I stepped in with creative ideas and offered multiple solutions so they could pick what worked best for them.

Pivitoing when Necessary

When updates didn’t work or weren’t feasible, I worked with engineers and product to adjust. We found solutions that kept things consistent without slowing the team down.

Leadership and Ownership

I led efforts to improve usability across the system. I cleaned up components and tweaked any custom components to achieve the team or clients ask. I also helped define new components that made work easier and more efficient for everyone.
