Joonas Lehtinen

Founder of Vaadin

Dr. Joonas Lehtinen is the founder of Vaadin - a web framework, component library and development tools used by 150,000+ developers worldwide. He leads a team of 140+ people mostly based in Turku, Berlin and Silicon Valley who live, breath and write open source with passion to help people build better web apps.

During the past 20 years Joonas has been working on most aspects (and bumping to way too many challenges) of a growing international VC funded tech company. While not in a hangout to 10 time zones away from San Jose where he is based, you can probably find him speaking in a developer conference somewhere in US or Europe. Or trying to convince you to join the team!
