February 2026 focused on delivering cross-repo fuzzy search capabilities for qualifications, enabling more accurate and faster retrieval. Implementations span API, web UI, and endpoints with pagination support. A feature-flagged rollout was used to mitigate risk while enabling staged validation. The work includes Lucene-based fuzzy search, updated query handlers, API request/response models, tests, and pagination across services.

Monthly Summary for 2026-01: Overview: Delivered end-to-end data import capabilities for Defunding Lists and PLDNS across web UI, API, and background jobs, with improved reliability, test coverage, and code quality. Achievements span feature delivery, bug fixes, performance tuning, and enhanced observability, driving data accuracy and faster onboarding of new defunding data sources. Key features delivered: - Data Import for Defunding Lists and PLDNS (web): Added import feature with improved error handling, user feedback on file uploads, reduced code duplication, and new app setting for import blob storage; dashboard and UI tweaks to improve focus handling and error visibility; expanded test coverage. - Defunding Lists and PLDNS Import (API): Implemented API support for imports, including database schema changes and data seeding scripts to enable initial data population and smooth migrations. - Import Pldns and Defunding Lists (jobs): Implemented background import functions with enhanced logging, error handling, and test coverage; tuned batch sizes for DB inserts to optimize performance. Major bugs fixed: - Resolved SonarCloud issues and refactoring needs across the import paths to improve maintainability and reduce technical debt. - Fixed unit test failures in the web import feature and addressed warnings in import logic. - Improved error messaging so success notices are displayed only when an action (e.g., email send) succeeds; cleaned up duplicate code paths. - API and jobs refactors addressed post-review comments, and updated routes to align with new import functionality. Overall impact and accomplishments: - Enabled reliable ingestion of critical defunding and PLDNS data, accelerating data availability for downstream processes and decision-making. - Improved data quality and consistency through schema changes, data seeding, and better error handling. - Achieved measurable performance gains from batch size tuning and optimized DB operations, supporting higher throughput for large imports. - Strengthened code quality, test coverage, and observability (logging, error feedback), reducing risk in future changes. Technologies and skills demonstrated: - .NET/C# backend development, API design, and data migrations; SQL data seeding and batch processing. - Refactoring for SonarQube compliance; code deduplication and helper class consolidation. - Logging, error handling, and user-centric feedback in file upload workflows; test-driven development and expanded test coverage. - Background processing and job orchestration for data imports; performance tuning of batch inserts and HTTP client usage.
