Roberto Martinez

Web Developer




I'm Roberto, I work as a web developer and I have a penchant for UX. On the last 10 years I have developed dozens of commercial websites, a good number of iPad apps for Fortune 500 companies and a few web apps going from marketplaces to SaaS.

Technology is always changing and I'm always learning. I like to try new things and build products.

Besides that I love my cats, the fall, playing tabletop games and my family. If you like board games, checkout my project Tokentile

You can find me on Hacker News, Github, Dribbble
