During a two-month period, Kyrylo Tkachov focused on backend improvements for the fictadvisor/fictadvisor repository, delivering targeted refactors and feature enhancements. He restructured the Teacher management module using NestJS and Prisma, improving code organization and expanding unit test coverage to support maintainability and reduce regression risk. In December, he refactored the TelegramGroup API controller, introducing endpoint-specific documentation decorators and refining DTO validation messages for clearer error reporting. Working primarily with TypeScript and JavaScript, Kyrylo emphasized clean architecture and robust validation patterns, resulting in more reliable APIs and streamlined future development without introducing new bugs during this period.
