José Vizcaíno

I’m a Product Engineer with a deep focus on crafting polished interfaces and building scalable web experiences, currently at Flowable. I bridge the gap between design and engineering, using collaboration and clean architecture to build digital products that are as performant as they are intuitive.

My background includes building tools for designers at Sketch and architecting Design Systems for enterprise applications at XING.

Outside of work, you’ll find me practicing calisthenics, attempting (unsuccessfully) to surf — or just geeking out over learning Japanese.
