We don’t just design interfaces.
We engineer the psychology behind them.

Bridging the gap between Cognitive Science and Shipped Code.

From Observation to Execution.

For a decade, I operated as a traditional UX consultant. I realized that design doesn't stop at the pixel. It stops at the logic. To truly control the User Experience, you must control the System Architecture.

Most agencies hand off a Figma file and hope for the best. We view that as a failure of responsibility.

Today, Proto UX is a Logic Architecture Lab. We don't just hand you a blueprint; we pour the foundation.

Redefining 'Proto'

Prototype↓PROTOCOL

In 2016, Proto stood for Prototype. In 2026, it stands for Protocol. We design the protocols that govern how humans interact with intelligent systems.
