Hermes Juan González Stark

01 — About

I'm a senior product designer with 9+ years of experience designing complex B2B and B2C digital products across healthcare, compliance, SaaS, and nonprofit sectors. I specialize in translating intricate business requirements into intuitive, scalable user experiences — from discovery and research through to delivery.

I'm experienced working within structured design systems, Agile/Scrum teams, and regulated environments. I actively integrate AI tools into my design workflow and have a strong foundation in accessibility, information architecture, and cross-functional collaboration with international teams.

I'm also the founder of 55.design, a product design consultancy based in Asunción, Paraguay. I also write about design career, process, and tools on Primer Pixel, a blog for designers starting or growing their careers in Latin America.
