Alex Soloviev
Over six months, contributed to the DTS-STN/vacman repository by designing and implementing core backend features for user, request, and match management. Leveraging Java, Spring Boot, and JPA/Hibernate, developed RESTful APIs with robust data models, event-driven workflows, and scalable pagination. Introduced automated matching, centralized notification systems, and integrated Microsoft Entra ID for identity management. Enhanced data integrity through validation, refactored payloads for efficiency, and improved onboarding with local development environments. Focused on maintainability and auditability, the work included configuration management, caching, and comprehensive test coverage, resulting in a reliable, extensible backend supporting complex business processes and secure data handling.

Sep 1, 2025September 2025: Delivered a consolidated overhaul of the DTS-STN/vacman Requests domain, introducing REST API endpoints (PUT/GET/DELETE) and a complete lifecycle with events (vmsNotRequired, PSCNotRequired/PSCRequired, complete) plus a feedback submission path. Implemented a centralized notification system with HR inbox, multi-address emails, and parallel processing, improving reliability and user experience. Migrated notification routing to GD email and ensured delivery to both personal and business emails, with endpoint naming alignment for maintainability. This work reduces manual follow-ups, speeds up processing, and provides clear visibility into state transitions and user feedback.
