## About

​

## Experience

- **Senior Product Engineer at Bluesky Social** (2025 – present)
- **Lead Backend Engineer at Rings AI** (2024 – 2025)
  It is my responsibility to refactor the backend of the product for scalability. The criteria for success are reducing cloud, increasing code quality and technical culture, as well as allowing the platform to onboard 100 to 1000x more users.
  • Design and implement modules for reusability in different parts of the stack
  • Identify performance bottlenecks and implement alternative solutions in code and architecture.
  • Create patterns and documentation for code quality, as well as automate code quality checks
  • Promote proactivity, transparency and collaboration in tech conversations within the team
- **Senior Software Development Engineer at Jusbrasil** (2019 – 2019)
  As a developer I engaged in technical challenges like porting large amounts of data from NoSQL to graph architecture, updating internal Python libraries and contributing to the the team with code reviews and technical solutions to production bottlenecks.
- **Program Manager at Open Knowledge Brasil** (2018 – 2019)
  Co-Founder of Operação Serenata de Amor, an open source project to empower social control of government expenses using data science. This project was incorporated as the Data Science for Civic Innovation Programme at Open Knowledge Foundation Brazil.
- **Graduate Teaching Assistant at University of Essex** (2014 – 2015)
  During my Ph.D., I was assigned to the Sociological Imagination module, an introductory course for first-year students in the Department of Sociology. Wright Mills's book inspired the syllabus and the course covered different topics in sociology, such as race and gender, labor, poverty, social classes, and consumption.
- **Project Leader at Insitum: Innovation through research** (2010 – 2012)
  Project leader focused on in-depth social research and innovation processes. The position also involved project and team management, as well as communication with clients, (including corporations such as Panasonic, Itaú Bank, Renault, Google, Telefonica and Natura).
- **Graduate Teaching Assistant at Universidade Federal de Santa Catarina** (2008 – 2008)
  During my Master's, I was assigned to the Social Theory course, a compulsory course for the third semester of the Social Sciences degree. I taught and discussed the social and political theories and thoughts of George Simmel and Max Weber in these classes.
- **Web Developer at Media Effects Group** (2005 – 2006)
  Development of digital material focused on user interface and new technologies.
- **Developer at Shopify** (2020 – 2023)
  I work at the Quality & Trust Automation building tools to improve the quality of third-party apps from the Shopify App Store.
  • Implemented merchant-facing features using generative IA related to Shopify's App Store;
  • Implemented a new payout system for third-party developers using multiple payment methods, such as bank accounts, PayPal, and others;
  • Automated the queue for manual audits in the Shopify App Store, allowing our operations team to invest time in the most pressing issues;
  • Enhanced tooling for the operations team to better understand the quality of third-party apps;
  • Automated dozens of quality checks for every app available in the Shopify App Store;
  • Prototyped new implementations and solutions using Go and Rust for higher performance and availability;
  • Contributed to open-source libraries maintained by Shopify.
- **Fellow for Civic Engagement & Agile Bank Program at World Bank Group** (2019 – 2020)
  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.
