Andrey Katkov developed and enhanced core API features for the s21platform/gateway-service repository over a two-month period, focusing on backend development with Go and gRPC. He implemented the Advert Creation API, connecting the gateway to the underlying gRPC service and consolidating data models for maintainability. Andrey also introduced end-to-end API tests to ensure robust behavior and reliability. In the following month, he realigned the Advert API endpoints to follow REST conventions, improved code quality, and added a cancellation workflow for adverts. His work emphasized API contract clarity, service integration, and maintainable data modeling, supporting future feature expansion and developer onboarding.

March 2025 focused on aligning the gateway-service Advert APIs with REST conventions and strengthening the cancellation workflow. Delivered two feature updates with targeted API realignment and a new cancellation path, completed targeted code quality improvements, and laid groundwork for more resilient RPC interactions. These changes improve developer experience, reduce ambiguity for API consumers, and enhance maintainability across the gateway surface.
