Joonas Javanainen

Joonas Javanainen worked on the espoon-voltti/evaka repository, focusing on backend improvements related to authentication and system integration. He developed a PlantUML architecture diagram to clarify how Koski integration operates within the AWS environment, detailing component interactions and data flow for updating information. Additionally, he refactored the SAML authentication stack by replacing @node-saml/passport-saml with @node-saml/node-saml, reducing dependencies while maintaining authentication functionality. Using JavaScript, TypeScript, and PlantUML, Joonas enhanced maintainability and security, enabling faster future changes and more reliable data exchange with Koski. The work demonstrated thoughtful system design and clear technical documentation.
