Design that makescomplex workfeel simple.

I'm John Dentino, a senior product designer based in Colorado. I specialize in 0→1 product work and complex workflow design, the kind of problems where the real work is deciding what to build, aligning stakeholders, and iterating until it's right. My process runs from discovery to delivery. I test with users, measure after launch, and optimize until the work lands.
