I worked on three different fronts: operations, corporate, and knowledge sharing. On operations, I contributed to projects in Africa and Asia: Mozambique (digital response to COVID-19 at the level of the Ministry of Health's National Health Institute), Nigeria (connecting the local civic tech communities and civil society engagement to empower monitoring and evaluation platforms for local sub-projects), Kazahstan (theory of change for a project focused on artificial intelligence and smart cities), Guinea (designing the implementation for an integrated system for citizen engagement at three different levels; national, sub-national, and community levels), and Niger (discussing the digital infrastructure and the strategy for the implementation of an early-warning system). Also, I was part of the Citizen Engagement Secretariat, joining the discussion with World Bank staff and other civil society organizations providing feedback for on-going operations in countries such as Tanzania, Iraq, and Malawi. On the corporate side, I delivered, with the Agile team, three workshops in Kazakhstan for the country and regional offices and members of the federal government. There and in the headquarters in DC, I also delivered clinics focused on agile methodologies, mainly Kaban and Scrum. Finally, on knowledge sharing, I co-organized and acted as a panelist in the panel "Government as a platform and Civil Society participation" at the Global Partnership for Social Accountability Forum (2019), contributed with posts to the Governance blog on civic tech and social media accounts, and co-authored a paper on fraud detection in the public sector.
