Work History

February 2026

1 Commits • 1 Features

Feb 1, 2026

February 2026 focused on delivering a core capability to extend resource schemas and simulate correlation mappings within the Evolveum/midpoint project. The introduced feature enhances the fidelity of resource integration tests, supporting more accurate evaluation of correlations and paving the way for scalable resource schema customization. This work improves deployment confidence for integrations and reduces time-to-value for onboarding new resources. No major bugs fixed this month; ongoing maintenance continues in parallel. Overall, the month delivered solid technical progress and sets a strong foundation for future work.

Jan 1, 2026

January 2026 monthly summary for Evolveum repositories. Key business value delivered this month centers on stronger correlation simulation capabilities for resource integration, coupled with maintainability improvements and developer guidance. Key wins: - Enhanced Correlation Simulation in midpoint to support additional mappings and suggested correlations, enabling simulations with extra resource mappings, parsing schemas with non-stored mappings, and correlators that use these mappings. This required updates to CorrelationSimulationActivityRun and CorrelationWorkDefinition, with new tests validating the feature. - Code clarity and naming consistency for correlation simulation: refactors to rename simulation handler classes and align type names and suffix conventions, with corresponding test updates and a missing Type suffix addressed for an XML complex type. - Documentation improvement in docs: added comprehensive XSD container annotation documentation, including usage, benefits, and best-practice recommendations. Overall impact: - More accurate and flexible correlation simulations reduce manual mapping effort and enable faster, more reliable resource integration. - Clearer, more maintainable codebase and improved developer onboarding through consistent naming and thorough documentation. Technologies and skills demonstrated: - Schema parsing with non-stored mappings, enhanced simulation workflow, test-driven development, refactoring for maintainability, and comprehensive documentation.
