In October 2025, Mohammad Etaati focused on improving the REST Client tutorial within the dotnet/docs repository by addressing a JSON deserialization issue. He refactored the Repository model to a C# record, introduced explicit JSON property mappings, and ensured case-insensitive deserialization, aligning the model closely with the API’s payload structure. Mohammad also updated Markdown documentation to clarify usage and reflect the revised schema, removing obsolete properties for consistency. By leveraging his skills in API integration, C#, and technical documentation, he reduced deserialization errors and enhanced the reliability and clarity of the tutorial, contributing to a smoother developer learning experience.
