OpenAPIを利用したPythonWebアプリケーション開発
The document outlines the work of a software engineer at Kabuku Inc., detailing expertise in Python, TypeScript, and Go, along with participation in various tech conferences. It also discusses the OpenAPI specification and its tools, including how to validate and unmarshal API schemas, especially focusing on a 'book' object schema. Several code examples illustrate the process of handling OpenAPI documents and their respective data validation.
