Problem

The original platform was visually disorganized and outdated, creating a dangerous environment for high-stakes trading.

Specialists reported feeling "overwhelmed" by the dense data display, leading to significant anxiety regarding potential administrative errors.

The lack of clarity in the UI directly increased the probability of costly financial mistakes.

Goal

To develop a clean, highly organized, and intuitive interface that prioritizes data legibility and reduces the user's cognitive load, ensuring error-free execution throughout the trading day.

Our Users

Our primary users are GBM internal specialists who manage the stock market in real-time. Their workflow demands absolute data integrity and an interface optimized for rapid scanning and decisive action under pressure.

Process

I led the redesign by bridging the gap between existing mental models and modern UI standards:

In collaboration with UX Research, I conducted executive interviews to deconstruct the previous software’s functionality and identify specific friction points.

We mapped out the complex mental models of the specialists to reorganize data into a hierarchy that follows their natural decision-making flow.

Developed a series of low-fidelity proposals to validate the new user flow before moving to high-fidelity execution.

I implemented a flat design aesthetic specifically to handle the high density of financial data. This minimized visual noise and maximized readability, allowing users to process "large-scale data sets" with ease.

Final Impact and Results

The transformation of the Transactional System resulted in a tool that prioritizes the user's peace of mind:
