Webdeveloper (1995+), usability and accessibility consultant (1997+), I've worked at Prodigio (Digito, Mail.pt, Evolui.com) and other big companies and projects doing webdevelopment, interface engineering, user experience, usability and accessibility.
I'm also founder of 4 Ventos (and previously 2 other companies). In 2001 I started Usabilidade.net, the first portuguese blog about usability and UX.
