PROFILE
Margarida Dias
Over three months, contributed to the tmlmobilidade/sae repository by building features that enhanced observability, financial analytics, and data-driven reporting for transit operations. Developed a command-line tool for daily performance metrics synchronization and introduced metrics to quantify passenger demand impact during outages. Leveraged Node.js, TypeScript, and MongoDB to integrate agency pricing data, enabling trip cost and revenue analytics, and established executive summaries with standardized passenger impact estimation. Focused on robust data aggregation, code maintainability, and accurate date handling, the work improved operational visibility and supported financial decision-making without introducing major bugs, emphasizing quality, testing, and scalable backend development practices throughout.
