Type: case-study

## Role

Front-end Architect & Lead Developer

## Overview

A reusable front-end architecture baseline for the Common UX/UI Framework (CUUF), created to support consistent internal application development across teams. It formalized patterns for application structure, routing, styling, accessibility, shared UI behavior, and developer guidance.
Focus: turning early framework decisions into a reusable, documented front-end baseline.

## Challenges

Internal applications often begin with the same front-end decisions: routing, layout, styling, reusable UI patterns, accessibility, environment configuration, and onboarding. Without a shared foundation, each team makes those choices differently, creating inconsistent implementations that become harder to maintain as more developers and screens are added.

The challenge was to create a baseline that supported active delivery without becoming too rigid or too abstract for real project teams to use.

## Process & Solution

- Established application structure, routing patterns, and layout conventions for internal front-end projects.
- Defined reusable styling and component patterns to reduce one-off implementation decisions.
- Built accessibility expectations into the foundation instead of treating them as late-stage fixes.
- Created an onboarding documentation set for teams adopting CUUF, covering setup, architecture conventions, auth patterns, accessibility expectations, curated Section 508 resources, and portable NVDA guidance for practical screen reader testing.
- Adapted front-end architecture patterns first established on ODIN, an earlier internal application, into a broader reusable baseline.
- Formalized the CUUF foundation so future teams could start from clearer implementation expectations.

## Outcome

The CUUF baseline gave internal front-end projects a clearer starting point. It reduced repeated setup decisions and gave adopting teams a shared reference for architecture, authentication, accessibility, implementation expectations, and practical 508 testing.
