Andrey Ryzhenko developed a privacy-focused feature for the MarkTheHopeful/TrackMyOffer repository, enabling anonymous CV generation through the backend API. He introduced an isAnonymous boolean parameter to the CV generation endpoint, updating both the request DTO and the OpenAPI schema to ensure consistency and maintainability. Working primarily with Kotlin and YAML, Andrey applied REST API design principles to evolve the server-side logic, supporting privacy compliance and expanding use cases for users concerned with data anonymity. The work demonstrated careful attention to API usability and schema documentation, laying a foundation for future privacy-aware workflows without introducing new bugs during the period.
