Worked on the apache/avro repository with a focus on improving decimal handling in the .NET implementation. Addressed a bug in AvroDecimal.CompareTo to ensure correct comparisons between decimals with different scales, which is essential for maintaining data integrity in cross-language serialization scenarios. The solution involved updating the comparison logic in C# and enhancing unit tests to be culture-invariant, thereby reducing locale-dependent test failures and increasing reliability in continuous integration pipelines. Demonstrated skills in C#, software development, and unit testing while aligning the fix with AVRO-4162, ultimately supporting more deterministic and reliable financial and precision-critical data workflows.

May 1, 2026May 2026 monthly summary for apache/avro (dotnet focus). Key work centered on correctness of decimal handling in AvroDecimal for cross-scale comparisons in the .NET implementation. Delivered a fix for AvroDecimal.CompareTo to correctly handle decimals with different scales and updated tests to be culture-invariant and reliable. This work aligns with AVRO-4162 and reduces data integrity risks in cross-language serialization. Impact and business value: - Ensures deterministic, cross-language decimal comparisons, improving data fidelity in financial and precision-critical workflows. - Eliminates locale-dependent test failures, increasing CI reliability and release confidence. Technologies/skills demonstrated: - C#/.NET, Avro decimal type handling, regression testing, culture-invariant testing, issue tracking (AVRO-4162). Top commits: - 5af5735cec1ed939ad40f4f599e099fd2d2b29e8: AVRO-4162: [csharp] Fix AvroDecimal.CompareTo for values with different scale (#3744)\n\n* fix(AVRO-4162): dotnet AvroDecimal.CompareTo for values with different scale\n* fix(AVRO-4162): Make tests not culture-sensitive
