Worked on the a-sit-plus/valera repository over a two-month period, focusing on backend development and API integration using Kotlin. Delivered two features that expanded Qualified Trust Service Provider (QTSP) integration, including support for NAMIRIAL and enhancements to KPI data collection through header propagation and fallback mechanisms for credential retrieval. Addressed reliability and scalability by implementing configuration-driven design and robust error handling. In the following month, resolved a critical bug to ensure credential identifiers were consistently included in API responses, improving data integrity and traceability for downstream processes. Demonstrated a methodical approach to building resilient, extensible signing workflows and credential management.
April 2025 monthly summary for developer performance review. Focused on API reliability, data integrity, and end-to-end traceability in the a-sit-plus/valera repository. Delivered a critical bug fix that ensures downstream operations can reliably reference credentials, reinforcing the integrity of credential workflows.

March 2025: Delivered two key features in a-sit-plus/valera that expand QTSP integration and improve KPI data collection, focusing on reliability and scalability. Implemented QTSP Handling Improvements to pass Wallet-QTSP-ID header during PDF processing to enable KPI collection, and added a fallback to query /credentials/info when /credentials/list lacks embedded credential information. Added NAMIRIAL QTSP Integration by updating defaultSigningConfig with NAMIRIAL API endpoints and configuration to enable NAMIRIAL signing services. No major bugs reported in this period. Impact: enhanced signing workflow reliability, broader QTSP ecosystem coverage, and improved KPI-driven visibility. Technologies demonstrated: REST API integration, header propagation for context, error handling with fallbacks, and configuration-driven design.
