Project Highlights

LATAM Open Mapping Hub –2022

Led the Community Strategy around the org presence and support to the Latin America region, where I helped recruit and launch a staff-team that, in under 5 months, resulted in dozens of new community-centric projects, hundreds of positive new relationships developed in 16 countries and a longer-term Hub plan and model.

Building Common Voice –2018-2020

Designed a global contribution strategy for crowd-sourced open data collection and a self-sustainable community model. Through regular and focused engagements, the number of internal and external contributions was boosted by a factor of 15x, resulting in the biggest voice open dataset, allowing to kickstart the unlocking of the closed voice recognition industry.

OpenStreetMap Modernization – 2021 -2022

I supported OpenStreetMap Foundation with its community channels modernization, where I led the scope and design of a change management plan, drove community consultations and enabled community-ownership of the new platform. In the first 4 months of the new platform launch, almost 1000 users, 6 local OSM communities transitioned over, with over 60 new topics per month.

Mozilla Community Portal – 2019-2020

Led the development of the Mozilla Community Portal, a culmination of years of community strategy work and, in just 6 months, the portal reached more than 4000 contributors in 87 languages, 160 groups from 40 countries, 263 events, and +45K subscribers to the campaign’s newsletter. The portal activities and campaigns were recognized as direct value to Mozilla key products and services.

Mission-Driven Mozillians – 2017-2020

Led the modernization of Mozilla’s global communities aligning contributor motivation to organizational needs and priorities, and, by designing impactful opportunities for contribution, I unlocked Mozilla’s communities as a powerhouse of innovation. As an example –  In the PlayStore Support Campaign, 431 volunteers replied to 2200 reviews in a week in 9 languages, or the Firefox Preview Bug Hunter Campaign with more than 500 issues filed and 8000 installs in just two weeks that were fundamental to launch this browser to the market.

Content Localization pilot – 2019

Based on past learning optimizing localization, I led a pilot to understand how to modernize our content localization strategies, which included external research and alignment with other organizations like Wikimedia.

The pilot helped understand how leveraging a more distributed review system together with machine translation can result in increased contributors engagement, experience and satisfaction, time-to-deliver, and huge cost savings. This work shaped the strategy moving forward in scenarios of low resources and increasing demand for internationalization.

Localization research – 2018

Lead an internal study to understand the health of localization communities, coordinating an external agency, introducing for the first time the concept of “health score” and bringing focus to languages that bring more impact to the products.

As a result, the localization team implemented a set of leadership agreements and role expectations that helped language communities to modernize their diversity and inclusion as well as be more effective.

Communities research – 2017

As part of our data-driven approach to revitalize participation by understanding our communities, I helped coordinate the contributors and communities research, connecting an internal and external multi-stakeholder team to generate a quantitative and a qualitative study on our communities. 

The result shaped the community approach and strategy in the following years and informed the recognized “Open by design” strategy.

Volunteering & Contributor

Mozilla Reps Program – 2010-2020

I took part in the foundation of the Reps program, a community-led program of core contributors who can self-provide the resources needed to run activities to support Mozilla. It’s still the oldest living project at Mozilla together with Firefox desktop.

Reps keep supporting major Mozilla products mobilizing communities through campaigns and events, from the Firefox OS Launch, to the launch of every Firefox major release updates, to the Privacy Month or Web literacy.  To date, 261 Reps have run more than 7K events, and reported 50K+ activities.

Mozilla communities – 2004-2014

I started contributing to Mozilla in late 2004 as a volunteer, supporting the efforts to localize websites (MDN and mozilla.org), being the Spanish content localized lead at the time.

I led the creation of the umbrella Spanish-speaking community “Mozilla Hispano” which grew from 7 founding members to hundreds of contributors in 20+ countries. I coordinated the efforts to define its governance, internal processes, tools, and infrastructure, that resulted into the most well known and impactful community at the time and it was key for Mozilla’s Firefox OS launch on the Spanish markets, including our participation at the Mobile World Congress 2013.

During this time I ran several public talks and events across Spain talking about Mozilla, privacy and open policies, as well as a podcast with more than 1000 subscribers.
