Full bio
I graduated in Art Education with a focus on Graphic Computing and Multimedia from Anhembi Morumbi University in 1998, where I also completed a postgraduate degree in Hypermedia Design in 2001.
My career in technology began in 1998 as a Web Designer, creating dozens of websites using HTML 3.2, table-based layouts, 3D animations, and Macromedia Flash. Prior to that, my exposure to technology included software such as Lotus 123, Printmaster, and programming courses in BASIC and dBASE.
In 2000, I won the Starmedia National Website Competition in the “inustiados” category with one of my personal projects.
I began working at NIC.br as a Webmaster for sites such as the Internet Steering Committee and Registro.br, among others. I was responsible for updates and design across these sites, contributed to creating their new visual identity and the “.br” logo in 2005, and developed several websites for international events such as ICANN São Paulo 2006.
With the publication of Decree No. 5.296 in 2004, which established mandatory accessibility for government websites, I began specializing in the field. In 2007, I came across the video “Web Accessibility – Cost or Benefit,” which sparked my passion for the subject and introduced me to my mentors in web accessibility: Lêda Spelta, Horácio Soares, and Marco Antônio de Queiroz (MAQ).
In 2008, the Web Content Accessibility Guidelines 2.0 (WCAG 2.0) were published. From that point on, I intensified my studies on web accessibility, creating a single PowerPoint file with more than 900 slides, encompassing all recommended techniques to make content accessible.
Also in 2008, I had the opportunity to attend the launch event of the W3C Office in Brazil, where I listened to a message from Tim Berners-Lee about the significance of having a W3C presence in Brazil—the first in Latin America.
In 2009, I took a web accessibility course with my mentors Lêda and Horácio (photos from the course are available on Flickr). Later that year, I gave my first lecture on the subject at CONIP 2009.
I began getting more involved with the topic, writing articles, participating in events, and giving lectures.
At NIC.br, I took part in several editions of the International World Wide Web Conference (WWW):
- WWW2010 (Raleigh, USA): contributed to Brazil’s successful bid to host the 2013 edition.
- WWW2011 (Hyderabad, India): joined the W3C Brazil team.
- WWW2012 (Lyon, France): participated in preparations for the 2013 event.
- WWW2013 (Rio de Janeiro): worked on organizing the event, which was a great success and engaged the developer community.
In 2014, I coordinated the publication of the Web Accessibility Handbook by W3C Brazil, in partnership with the Public Prosecutor’s Office of São Paulo, resulting in six booklets. That same year, we led the authorized translation of WCAG 2.0 into Portuguese – the first authorized translation of a W3C standard in pt-br. I also coordinated the translation of the WCAG 2.2 version, published in 2025.
I also participated in all W3C Brazil Web Conferences, starting in 2009 (as an attendee) and, from 2011 onward, as part of the event’s organizing team.
Between 2013 and 2016, I coordinated the National Web Accessibility Award, which recognized websites accessible to people with disabilities. The last edition was held during the Rio de Janeiro Paralympic Games.
I am the author of two books on web accessibility:
- Web Accessibility (Editora Senac, 2017)
- Web Accessibility – Best Practices for Building Accessible Websites and Applications (Casa do Código, 2022)
I also wrote for IMasters magazine between 2013 and 2018, publishing a total of 34 articles. I contributed to Tableless (16 articles), the W3C Brazil Blog, among others. Academic publications, including papers for national and international conferences, number more than ten.
I have been a speaker at hundreds of events in Brazil and abroad, such as BrazilJS, HTML5 Dev Conf, TheWebConference, several editions of “Front in,” and academic events. Some of these talks were recorded and are available online.
I coordinated the ABNT Study Committee responsible for developing the standards:
- ABNT NBR 17060 (Accessibility in Mobile Applications, 2022)
- ABNT NBR 17225 (Accessibility for Web Content and Applications, 2025)
I have also worked as an extension course professor at PUC São Paulo. Since 2022, I have been teaching the course Accessible Interface Design, aimed at educating students about digital accessibility.
In 2023, I received the HandTalk Accessibility Leaders Award, a national recognition for my work and dedication in the field of digital accessibility.
