Start from the stuck user and the business constraint, then design the shortest honest path between them.

About
A designer who asks how it works.
AI can draft an interface in minutes. The part it can't do is the job I care about: framing the right problem, judging which draft deserves to ship, and making sure it still works once it's built.
My Informatics Engineering background means I design with the build in mind. I prototype in code and ship my own products, like ViRef.ai.

The defaults I work by.
Design is a translation job
Research, business goals, and technical constraints, translated into one experience that feels obvious.
Judgment is the toolkit
Knowing what to prioritize, what to simplify, and which trade-offs serve the product. Tools change; judgment travels.
Design that ships
An interface is not finished when it looks right, but when it works in the world.
