Kartik Jain developed and enhanced backend modules for the FOLIO platform, focusing on data governance, query optimization, and access control across repositories such as mod-fqm-manager and mod-lists. He implemented features like granular permissions, JSONB array support, and advanced FQL-to-SQL conversion, using Java, SQL, and Spring Boot to improve data retrieval and security. Kartik also expanded integration test coverage and automated workflows, ensuring robust multi-tenant data management and compliance with evolving requirements. His work addressed complex data modeling challenges, streamlined API usage, and maintained high standards for code quality, documentation, and internationalization throughout the development lifecycle.
January 2026 monthly summary for folio-org/mod-data-export. Focused on delivering core features, increasing test coverage, and aligning workflow with updated access controls. Key features delivered include Mapping Profiles Locking (lock/unlock functionality with API endpoints, permission checks, and DB schema changes to support locked profiles) and Holdings Export System improvements (test coverage for the export workflow and module descriptor updates with permissions fields). Also completed the removal/deprecation of the old mapping profiles lock method to reflect updated workflow. Major bugs fixed mainly involve removing the legacy lock path to ensure consistent state and governance. Overall impact includes improved governance, security, auditability, CI readiness, and safer migration paths for clients using export workflows. Technologies/skills demonstrated include API design, permission checks, DB schema evolution, test coverage strategies, module descriptor updates, and deprecation/migration planning.
