Leo developed comprehensive developer-facing documentation for the EppoPrecomputedClient API as part of the Android SDK 4.12.0 release in the Eppo-exp/eppo-docs repository. Focusing on clarity and depth, Leo detailed the API’s initialization, assignment methods, contextual bandits support, offline mode, and polling configuration, ensuring that integration steps were transparent for Android developers. The work leveraged skills in API design, Android development, and technical writing, using JavaScript and Markdown to structure and present the content. By aligning documentation with the SDK release, Leo helped streamline onboarding and reduced integration friction, though the scope was limited to documentation without direct bug fixes.
