October 2025 monthly summary for diadocsdk-csharp focused on API enhancement to support contracts with representatives. Delivered a new RepresentativeInn field across document contract types, with corresponding XML schema and C# model updates to capture the representative taxpayer identification number. This enables accurate handling of contracts that rely on a representative, improving compliance and data integrity in downstream processes. Implementation tracked under DDCORE-10447 and committed as 95f0f83c1469183751333d8fb0f24ba1ee00bec8. No major bug fixes were reported this month; primary value comes from extended data fidelity, streamlined workflows, and faster integration for customers needing representative information. Technologies/skills demonstrated include C#, XML schema evolution, API design, version control, and Diadoc API domain knowledge.

April 2025: Major feature delivery across C# and Java SDKs, expanding API coverage and improving data retrieval. Implemented 551/552 format support in the C# SDK and GetOrganizationsByInnListV2 in the Java SDK, enabling more robust processing of acceptance certificates and waybills, and more precise organization lookups by INN with optional box ID. No critical bugs reported this month; these changes enhance customer onboarding and integration efficiency. Demonstrated strong API design, samples/code generation, and backward-compatibility/deprecation planning.

March 2025 monthly summary for diadocsdk-csharp: Delivered two targeted features that strengthen integration capabilities and accelerate customer onboarding. Key outcomes include: - End-to-end UTD posting sample added to the SDK, demonstrating how to build the document title, sign, and send a Universal Transfer Document with realistic seller/buyer data, table content, and handling electronic powers of attorney (commit afdd52bd6361cd0af770fece1dd1358a56640f0f; DDCORE-9015). - API enhancement GetOrganizationsByInnListV2 introduced to query organizations by INN list with an optional box ID, serving as the preferred replacement for the older GetOrganizationsByInnList methods (commit 233f14dd50ffe39e5f05d821f294b926a646e531; DDCORE-8775). Major bugs fixed: None reported in this period based on the provided data. Overall impact and accomplishments: These changes improve time-to-value for integrations, enable more precise organization lookups across boxes, and provide an end-to-end example that reduces onboarding risk. The work directly supports customer deployments and internal maintainability by aligning features with explicit Jira/DDCORE references. Technologies/skills demonstrated: C#, .NET, API design and evolution, sample-driven development, end-to-end signing/sending workflows, and maintainability practices (clear commit messages and traceability to DDCORE issues).

February 2025 monthly summary for diadocsdk-csharp: Key feature delivery includes the Department Information Retrieval API V2, adding GetDepartmentV2 (boxId-based) and its async counterpart GetDepartmentV2Async, expanding retrieval options beyond the existing GetDepartment (orgId). This change is backed by commit DDCORE 8771: 'Add new method GetDepartmentV2 (by boxId)' (hash 1f503bf248ca9e3976da9869f8d2141108c0f95b). Business value: enables customers to retrieve department data using boxId, simplifying integrations and reducing dependency on orgId; improves responsiveness via async API. Tech highlights: C#, .NET, async/await patterns, API surface versioning, and code readiness for continued evolution. Overall impact: improved integration flexibility, faster lookup paths for department information, and a maintainable API extension in diadocsdk-csharp.
