Roberto Goelzer

Over two months, contributed to the onlynotes repository by building and refining features for Android, focusing on study tools like flashcards and decks with image support, public visibility, and enhanced search. Applied Kotlin, Jetpack Compose, and Firebase to deliver robust UI/UX, integrating animations, image pickers, and notification screens while maintaining a modular MVVM architecture. Prioritized code quality through consistent formatting, comprehensive documentation, and expanded test coverage, including unit, UI, and end-to-end tests. Addressed bugs and improved reliability by refactoring data models, stabilizing tests, and resolving edge cases, resulting in a more maintainable, scalable, and user-focused mobile application.
