Worked on the TykTechnologies/tyk repository to deliver security-focused improvements to API gateway configuration and documentation. Enhanced upstream authentication validation by implementing stricter schema validation and required fields enforcement, reducing the risk of misconfigurations and strengthening security. Upgraded the OpenAPI/Swagger specification to version 5.7.0, ensuring that documentation accurately reflected recent API changes and provided clearer contractual guidance for developers. Leveraged skills in API Gateway Configuration, documentation, and schema validation using JSON and YAML. These changes improved alignment between gateway behavior and API contracts, supporting safer deployments, easier downstream integration, and faster onboarding for teams working with the API gateway.
