UX architecture for complex product systems.

Ahoy! I’m JB Ong, a UX Architect who helps teams make complex products easier to understand, use, and evolve—through systems thinking, research, information architecture, and design leadership.

See the parts. Design the relationships.

Selected systems in practice.

Three projects where the interface was only part of the problem—and the relationships between people, technology, policy, and business shaped the solution.

Enterprise · Gaming · Caesars Sportsbook

I helped define how Caesars Rewards appeared inside a newly white-labeled sportsbook—connecting loyalty education, product requirements, research, design-system constraints, and multi-state delivery.

What collaborators say.

Perspectives from product, design, and technology leaders across complex systems and teams.

What sets JB apart is his holistic approach to design—he considers every angle and anticipates user needs with an almost uncanny foresight, ensuring that the final product isn’t just functional but also intuitive and engaging.

Fred Sosa · UX DirectorOptum

JB excels at presenting ideas and technical materials in a manner that tells a story while drawing the audience in and making them a partner and stakeholder of the experience.

Gary Cors · Product ManagerCaesars Entertainment

JB consistently demonstrates an easiness to build interpersonal relations with others. If you ever need someone to deliver under pressure, no slip-ups, just results, JB is your man!

Sofia Mohammad-Vaccaro · Product LeadGeneral Assembly

We needed a lot of help building our UX from the ground up and JB was integral in that process. He managed all of the user feedback and testing, worked on site flows, created a UX documentation process, and many other things!

Rachel Bailin · Product LeadSpylight

On occasion I have sought guidance from him on matters of information architecture, user experience and management and he would provide insightful and actionable advice.

Paul Mak · IT ManagerFitbit

I design the relationships between the pieces.

Salutations! I’m Jaynesis—commonly known as JB.

My path runs through fashion, entertainment, and technology—fields I’ve been around since childhood. That range taught me how to enter complex situations, find the meaningful connections, and build a useful path forward.

My studies in spiritual and narrative psychology shape how I listen, collaborate, and think about the stories a system tells through its behavior.

I approach design as a system: not just the interface, but the people, processes, incentives, constraints, and future consequences around it.
