I joined the World Wide Web Consortium (W3C) as Chief Development Officer in September 2024 to focus on setting direction and expanding development portfolio across internationalization, accessibility, privacy and security for the Web, ensuring the longevity of the organization by defining a vision for financial security.

I am a seasoned international development expert with 30 years’ experience across Latin America and the Asia Pacific. I have extensive experience in fundraising, design, management and reporting at local, national and regional level, leading purposeful collaborations that strategically use the Internet and the Web for social, economical, and cultural development.

Before W3C, I worked at APNIC for 16 years. During my tenure, I worked to establish the Information Society Innovation Fund (ISIF Asia); the Seed Alliance and more recently the APNIC Foundation, where I worked to expand its grant making, allocating close to 11M USD to close to 200 initiatives across 32 economies. I also led the design and implementation of a number of training and professional development initiatives addressing gender diversity and social inclusion in APAC.

Throughout my career I have served the Internet technical community on a variety of roles across a number of advisory bodies and selection committees related to Internet Governance, innovation, women in technology and professional development initiatives with a focus on the Internet industry, at a global and regional level. I have addressed many national, regional and international conferences.
