Over a two-month period, Mikhail Ardintsev enhanced the diadoc/diadocsdk-csharp repository by delivering regulatory-aligned tax calculation features and improving document workflow reliability. He updated the tax calculation data model to support new UCD 736 and 423 tax rates, removed obsolete rates, and refactored enums to ensure compliance and accuracy. Using C# and data serialization, Mikhail also improved Torg-2 document submission by refining signer handling and strengthening test coverage. His work included stabilizing the testing framework with NUnit, resulting in a more robust CI pipeline. These contributions deepened backend reliability and aligned business logic with evolving regulatory requirements.
