Rogério Araújo

Background

Rogério maintains the data and research systems that power PassportFactory. His background is in software development and structured data, and he applies that to immigration information: building the pipelines that ingest official-source records, designing the comparison tooling that lets travelers look at multiple passports side by side, and keeping ranking and visa-access data current as policy changes occur. His work sits at the intersection of data engineering and immigration research — making sure that the numbers behind each passport page are accurate, traceable to a source, and structured in a way that the site can use reliably at scale. He is particularly focused on the integrity of the comparison and ranking systems, which are the most frequently referenced parts of the site and the most sensitive to stale or mismatched data. Before PassportFactory, he worked across software development projects requiring rigorous data modeling and workflow automation.
