Emi Mariscal contributed to several open-source mapping projects, focusing on both frontend and backend improvements. For hotosm/fmtm, Emi delivered comprehensive internationalization and UI styling enhancements using Svelte and UnoCSS, migrating styles to semantic CSS and enabling dynamic theming with CSS variables. In hotosm/tasking-manager, Emi improved authentication reliability and security by refactoring login flows, replacing localStorage with a secure wrapper, and removing deprecated features for maintainability. Emi also implemented public API endpoints in hotosm/drone-tm using FastAPI and Python, expanding data accessibility for project centroids and details. Emi’s work emphasized maintainable code, localization readiness, and secure, scalable integrations.
Month 2025-11: Delivered backend public API endpoints for project centroids and details in hotosm/drone-tm, enabling programmatic access to centroid data and individual project information. This work enhances data accessibility for users and downstream systems, facilitating faster integrations and analytics. No major bugs reported; testing and stability remained solid. Overall, the month strengthened data reach and laid a foundation for API-driven features, supporting data-driven decision making and external tooling.
