Multiple client applications

At Relesys, I worked on a platform used to build internal communication apps for clients across different industries. Instead of focusing on a single product, my work spanned multiple applications, each with its own brand identity, requirements, and organizational context. The goal was always the same: make each app feel tailored and relevant, while working within a shared system. This is a selection of that work, shipped interfaces that show how design adapts across different clients without losing consistency.

Client Apps

50+ brands. Each one different. All built on the same foundation.

Each app was designed for a different client — different brand, different industry, different people using it every day. The layouts, the content, the visual language all varied. What stayed the same was the system underneath.

Selected Work

A closer look at some of the apps.

Each app was built for a different client, a different market, and a different group of people. Here's a selection of the interfaces we shipped.

Themes

Every brand, dressed for the occasion.

Alongside the core app interfaces, we designed a set of themes that clients could apply on top of their apps for specific moments,campaigns, seasons, and occasions. Each theme had to feel distinct and celebratory while still working within the brand and system constraints.

Reflection

Designing at scale changes how you think.

Working across this many apps taught me that structure isn't a constraint, it's what makes design work in the real world. It's not enough for something to look good. It needs to work consistently across different brands, different users, and different contexts. The hardest part was knowing what to keep consistent and what to let each brand own. Too much variation and the system falls apart. Too little and nothing feels distinct. Getting that balance right, that's where the real design work happens.

"Designing applications isn't about making them look beautiful, it’s about making them usable for real people, across dozens of brands, every day..."
