PROFILE
Maksym Khakimzhanov
Max Hakimzhanov contributed to the ita-social-projects/OoS-Backend repository by building and refining backend features that improved data integrity, access control, and workflow reliability for workshop management. Over six months, he delivered enhancements such as centralized provider title resolution, dynamic study subject associations, and robust draft moderation with role-based access control. Using C#, ASP.NET Core, and Entity Framework Core, Max implemented architectural refactoring, optimized data retrieval, and enforced validation logic to reduce technical debt and prevent invalid state changes. His work demonstrated depth in backend engineering, addressing both feature delivery and critical bug fixes to support maintainable, secure platform operations.

Aug 1, 2025August 2025 — Ita-social-projects/OoS-Backend: Delivered two high-impact changes to improve data consistency and maintainability. Key feature delivery: Provider Title Architecture Improvement via Provider.FullTitle, centralizing title resolution and removing direct ProviderTitle usage from Workshop and WorkshopDraft; updated repositories, services, DTOs, and tests to support the new approach. Commit 347e54fa391d3c4d4e0d71d848e6a577ab283c7d. Major bug fix: Draft Update Validation Under PendingModeration, preventing updates to drafts when status is PendingModeration and aligning validation messages with the updated rules. Commit 5a98db21c0ed2085dfce37492151f0432b7fde30. Overall impact and accomplishments: reduces risk of title inconsistencies and invalid draft state changes, enhances maintainability through architectural refactor, and improves observability with targeted logging. Technologies/skills demonstrated: C#/.NET backend, architectural refactoring, repository/service/DTO/test updates, and improved logging.

May 1, 2025May 2025 – Ita Social Projects OoS Backend: Key feature deliveries and stability improvements for workshop workflows. Implemented Workshop Study Period Scheduling (start/end dates on Workshop, DTO/services/database schema updates) with validation and data normalization; introduced Workshop Draft Moderation and Access Control (moderator edits, image management, RBAC-based authorization, new API endpoints), plus refactoring of draft mapping and validation and expanded tests. Fixed critical issues including removal of unnecessary study-period validation, corrected mapping in SetToDraft (WorkshopV2DtoExtensions), and enhanced draft filter validation with Moderator/TechAdmin authorization. The work improved data integrity, security, and end-to-end workflow reliability, delivering clearer business value for workshop operations and moderation.

Apr 1, 2025April 2025 backend delivery for OoS-Backend focused on data model cleanup for Workshops and enabling dynamic StudySubject associations. Key changes include removal of obsolete fields ShortStay and IsSpecial from Workshop (with DB migration) and full lifecycle support for attaching/detaching StudySubjects to Workshops (backend service, controller logic, DTOs, DB schema updates, enhanced retrieval with attachment status, and pagination). These changes reduce technical debt, improve data integrity, and enable richer program planning and analytics by providing cleaner data structures and flexible subject-workshop relationships. Technologies touched include database migrations, DTO evolution, API controller development, pagination, and Elasticsearch configuration updates.

Mar 1, 2025March 2025 — OoS-Backend: Implemented default values for hidden Workshop fields across mapping profiles. Refactored mapping logic to use IHasHiddenFields and an extension method to apply defaults, ensuring consistent handling during data transformations. This change improves data quality, reduces edge-case handling, and establishes a maintainable pattern for future defaults.
