GroupMe wasn't enough. Lambda Sigma Upsilon deserved something built for them.

Brothers of Lambda Sigma Upsilon Latino Fraternity Incorporated had no official platform for connecting and networking with one another. Communication happened in GroupMe and Facebook Groups — tools built for general audiences, not for a brotherhood with specific goals around community, professional development, and cultural identity.

Brothr 79 was built to change that. A platform designed specifically for the fraternity: connecting brothers across chapters, giving alumni continued purpose and career guidance, and aligning with the organization's four core goals.

GroupMe and Facebook Groups — the existing fragmented communication tools brothers were using
The current state: brothers connecting through general-purpose tools that weren't built for a brotherhood's specific needs.

80+ photos. 4 mood boards. One color system that held it all together.

I started the design process with an immersive brand research sprint: pulling from over 80 photos that were categorized, clustered, and synthesized into four directional mood boards — Dark Ocean, Dark Sky, Light Ocean, and Light Sky — all inspired by the visual language of the organization.

From there I developed a circular color grid: a quadrant-based system that showed how all four color directions could relate to each other, giving stakeholders and the team a clear picture of the full design space before committing to a direction.

Brothr 79 mood board 1 — Dark Ocean direction
Dark Ocean: deep navy and teal, grounded and authoritative.
Brothr 79 mood board 2 — Dark Sky direction
Dark Sky: near-black with bright accent — aspirational and high-contrast.

50+ screens. A modular system built for consistency at scale.

To manage the complexity of the full app — onboarding, dashboard, profile, messaging, search, support — I built a modular design system based on reusable components: cards, nibs, list items, and controls, each with their own states. The system allowed for flexibility in combining components while ensuring visual consistency and recognizable patterns for users.

The design system: component patterns, states, and type scale built for consistent use across 50+ screens.

Reusable components with all states defined — reducing design-to-development guesswork.
