PROFILE
Frederic Stahel
Worked on the swisstopo/swissgeol-boreholes-suite repository, delivering robust backend and frontend features for geospatial data management and borehole workflows. Over five months, developed and refined API endpoints, implemented secure and scalable data import/export in JSON and geopackage formats, and enhanced UI/UX for data entry and navigation. Applied C#, TypeScript, and React to improve code quality, enforce permission validation, and automate depth calculations. Focused on maintainability through code refactoring, comprehensive test automation with Cypress, and detailed documentation. These efforts resulted in more reliable data pipelines, improved onboarding for new data types, and streamlined user workflows for geospatial applications.

Nov 1, 2024November 2024 saw focused delivery across audit trail improvements, JSON export/import, API pagination, and code quality. Key user-facing improvements include audit trail UI enhancements showing changedAt/changedBy with borehole-name provenance, and a robust JSON export/import workflow with internationalization and tests. API scalability was enhanced with a borehole get-all endpoint with pagination; extensive UI/Cypress test cleanup and changelog maintenance reduced technical debt. Together, these efforts improve data traceability, bulk data operations, and maintainability, delivering measurable business value through faster data workflows and stronger data provenance.
