Abstract

I led the discovery, audit, improvement proposal, and redesign phases for a data-intensive operational platform used by operators at electric power companies.
The audit was structured in phases: discovery → findings → prioritization by impact/effort → recommendations. I combined heuristic evaluation (Nielsen), WCAG 2.1 AA accessibility guidelines, and ticket supports as evidence to lay the foundation for the redesign.

Delivered:

Report containing findings from usability and heuristic testing, along with suggestions for improvements.
Work plan for implementing the redesign.
Design system with variables, tokens, and reusable Angular Material and Tailwind-ready components.
Interactive prototypes in Figma.
Design specifications for development.
