Ishan Gajurel
Contributed to the FirelyTeam/firely-cql-sdk repository by delivering features and fixes focused on backend development, CQL runtime, and robust date and arithmetic operations. Over three months, implemented product line-based population support for annotations, enhanced arithmetic overflow handling, and improved unit normalization for datetime quantities using C# and XML. Refined aggregate calculations in the Sum operator to ensure accurate analytics and aligned submodule dependencies for stable releases. Streamlined XML schema to C# code generation, overhauled date duration logic with comprehensive tests, and increased data flexibility by relaxing group tag parsing. Emphasized clean code practices, unit testing, and maintainable solution management throughout.

Jan 1, 2026January 2026 accomplished four key items in the Firely CQL SDK: relaxing group tag parsing to support both integer and non-integer values; streamlining XML schema to C# code generation by removing the XsdToCSharpConverter; overhauling date duration calculations with new logic and comprehensive tests; and stabilizing the release by reverting the auto-update feature. These changes collectively improve data flexibility, reduce maintenance complexity, enhance accuracy of date-based calculations, and preserve system stability for downstream consumers.
