Following my involvement in transitioning the monolithic Rush.App to a microservices architecture using Kong, I decided to further bolster my expertise by completing the Kong Gateway Foundations course. This course wasn't just a learning journey but an official recognition of my practical skills and deep understanding in key areas like API gateway fundamentals, managing Kong Gateway in specific, API-first product design, the lifecycle of RESTful APIs, and OpenAPI specification. It covered everything from end-to-end gateway implementation management to the specifics of single-endpoint publishing.
