Anna Topalidi

I am a software engineer specializing in civic technology, with a focus on building open, scalable tools for public participation. Since 2022, I have been a contributor to Decidim—an open-source platform for participatory democracy used by governments and institutions around the world. Decidim powers citizen participation processes in cities like Barcelona, Helsinki, Paris, and Zurich. In 2024, the Brazilian federal government formalized a national-level partnership with the Decidim Association, aiming to bring the platform to millions of citizens. My work has been part of this ecosystem. Over the past years, I have contributed to the platform’s architecture, improved its modularity, and led the development of new features. In 2023, I played a leading role in one of Decidim’s most ambitious technical evolutions: integrating a full digital voting system into the platform. Before this work, Decidim supported deliberative processes, proposals, and participatory budgeting, but it lacked the ability to conduct formal voting within its core. Institutions that wanted to run verifiable digital votes had to rely on external or closed-source tools, which often conflicted with the transparency and autonomy values that define civic tech. I was responsible for designing and implementing the core elements that made voting possible directly within Decidim. That included the backend logic, admin flows, participant-facing voting interface, scheduling system, result display, and public traceability. I worked to ensure that the module followed platform conventions, was easy to adopt by cities and organizations, and could operate without introducing unnecessary complexity. This development has already been used in real-world decision-making contexts, such as the Decidim Association’s General Assembly. At the same time, all of this work was published as free and open-source software. I ensured the module was cleanly structured, documented, and extendable—allowing others to build on it across countries and contexts. My role combined technical leadership with product thinking and a deep understanding of how public-sector technology must work: reliably, transparently, and under public control. This nomination reflects both my technical contribution to a key innovation in Decidim and my broader commitment to building open, civic-focused digital infrastructure that can serve millions of people, today and in the future.
