Przemek worked on the Solvro/backend-eventownik repository, building and refining backend features to support complex event data management. Over four months, he designed hierarchical data models for nested blocks, implemented robust CRUD operations with data validation, and automated participant data workflows including Excel-based import and export. Using AdonisJS, TypeScript, and SQL, he ensured data integrity through cascading migrations and improved API reliability with comprehensive documentation and middleware cleanup. His enhancements to event export functionality enabled targeted data retrieval and clearer reporting, while integration of Autoswagger standardized API documentation. Przemek’s work demonstrated depth in backend architecture and practical problem-solving for maintainability.

April 2025: Key enhancements to the Event Export feature in Solvro/backend-eventownik, focusing on data clarity and targeted exports. Delivered a new query parameter to filter participants by IDs for event exports and improved handling of missing attributes by displaying 'N/A' instead of 'undefined' in the exported spreadsheet. Updated related documentation to reflect these changes and ensure consistent usage across teams. These changes reduce manual post-processing, improve reporting accuracy, and support better data-driven decision-making.
