Sebastien Dasys developed the HarmoniQ platform, delivering a robust foundation for weather and wind energy data analytics. Over five months, he architected and implemented backend systems using Python, FastAPI, and SQLAlchemy, enabling asynchronous data processing, multi-source integration, and schema-driven CRUD operations. His work included building scalable API endpoints, integrating MongoDB and SharePoint for data persistence, and refining the web UI with HTML and JavaScript. Sebastien addressed data validation, caching, and performance optimization, while maintaining code quality through automated formatting and documentation. His contributions to the Houjio/HarmoniQ repository improved data accessibility, reliability, and accelerated feature delivery for analytics-driven workflows.

April 2025 monthly summary for Houjio/HarmoniQ: Delivered batch-read capability, a robust CRUD endpoint for reading demande data, and expanded data integration for Team 9 and Eloise, establishing a solid foundation for multi-source analytics and data workflows. Implemented initial nuke functionality and completion workflow, and introduced asynchronous processing with caching to boost throughput. Quality and reliability improvements include code formatting with Black and cleanup of obsolete build files, as well as an updated database-downloading script.
