Guillen.
iOS Application Architect. I design the structural systems beneath the apps people actually keep on their home screen — building for clarity, longevity, and the quiet feel of software that just works.

02Philosophy
I design for the engineer who inherits this codebase — someone joining a year from now who needs to understand, extend, and trust what’s already there. Scalability and clarity aren’t trade-offs; they’re the same decision made well.
