Worked on the Adyen Java API Library, focusing exclusively on enhancing documentation for the Cloud Device API. Applied technical writing and documentation skills using Markdown to update the README, clarify API descriptions, and provide detailed timeout guidance. Improved the migration guide to streamline developer onboarding and reduce integration errors, ensuring consistency and clarity throughout the repository. No code or feature changes were introduced during this period, as the primary objective was to improve documentation quality. The work addressed usability challenges by making technical information more accessible, ultimately enabling faster integration and minimizing misconfigurations for developers working with the Cloud Device API.
