The Problem

Sim-racing telemetry and vehicle setup tools can expose drivers to large amounts of technical information. Perfect Sector was designed around a simpler question: how can that information be turned into something a driver can quickly understand and act on?

Product Flow

Core Driver Journey

Design Iteration

Designing Through Iteration

Before
Perfect Sector — Earlier interface, Sessions screen
After
Perfect Sector — Current interface, Home screen dashboard

Problem

The original interface grew around individual features, creating a cluttered experience with weak visual hierarchy and no clear path through the product.

What Changed

I simplified the navigation, removed visual noise, established a consistent design system, and reorganized the experience around Home, Tune, Telemetry, and Performance.

Why It Changed

The redesign shifted the focus from exposing features to helping drivers quickly understand where they are, what matters, and what action to take next.

What I Learned

Key Takeaways

Building Perfect Sector taught me that good product design isn't about adding more features. It's about making complex information easier to understand and act on. As the product evolved, I learned to simplify navigation, create stronger visual hierarchy, and design around the driver's workflow rather than the software's feature list.

The biggest lesson was to treat the interface as something that should evolve with the product. Testing Perfect Sector in real driving situations continually exposed friction, unclear interactions, and opportunities to simplify the experience, turning iteration into a core part of how I design.
