PROFILE
Arthur Muster
Arthur contributed to the SwEnt-Group8/Street-work-app by building and refining core authentication, user onboarding, and persistent preferences flows. He implemented a DataStore-backed preferences module and integrated it with the app’s sign-in and main navigation, ensuring user state and settings persist reliably across sessions and offline scenarios. Using Kotlin, Jetpack Compose, and Firebase, Arthur expanded the repository and ViewModel layers, introduced robust test coverage, and improved code quality through refactoring and formatting. His work addressed onboarding friction, enhanced error handling, and stabilized authentication, resulting in a maintainable codebase with comprehensive test automation and resilient user management features.

Dec 1, 2024December 2024 monthly delivery for Street-work-app. Focused on establishing a robust preferences persistence layer, integrating preferences with core app flows, strengthening authentication and onboarding, and expanding test coverage. Highlights: Key features delivered: - Preferences Module: added PreferencesRepository core and DataStore interface, enabling persistent user preferences (commits 13e0772405889517800326c9d1bbce8d13b137e8; 525d5335d9122843334b00e9ca3369b740fd197f). - Preferences ViewModel: implemented PreferencesViewModel and test scaffolding, accelerating test-driven development for preferences flows (commits 9b457974139f7b8e4dbc5fd5356da4abbdd88d17; 70ce7cbe2b930802b2d59dc1fb0deca338c6a845). - DataStoreManager and architecture alignment: refactor relocation to align with new architecture (commit 57fd946a08248e99f832606ce4d7a545bf060dc0). - Main/SignIn integration: wired Preferences ViewModel into Main and SignIn with internet availability parameter; start destination based on login state (commits e1294666359e46036de756b8fc9d00c4b3923d38; d25cb9d34750ee0a142a105015fe484337761a0e; ad6fee6fe87804157792b1a24524cfaccf5a59ab; 9d414a5c21c1ebb0d427c1439e59328eb8ec7e1c). - Auth and Google Sign-In enhancements: integrated Google Auth Service in main/settings and sign-in; context parameter support and test mocks (commits 004f717dde4025f4dc02e0f82762f531b54ad7df; d83a4eacabfcdf25e0119ab4ddccea8b32f14857; 1c82cdce6a292814a4e00f24f9f4650e2dc36bc6; d37c31e5cbf586b430ce5d8697c64d8d68111ba4; 3b60a48ccefca321576de3a112e90c289b38d950; 220c79fef03a09553c6354f3f7e6f2c7ae8fbe80). - Testing and quality: Splash screen UI tests, StreetWorkAppMain tests, and expansive test suite across parks, events, users, progressions, workouts; ktfmt formatting; test cleanup (selected test-related commits). Major bugs fixed: - Preferences: typos, documentation parameter rename, hardcoded strings replaced with constants, refined flow value names, and improved IO error messaging (commits 86c05e94c00fe1e9ca74188a717f8fedeaff43ee; fe609011b305c6dc694fe8dedd1de77f96bb6f5c; 236191c0ddc20a8c817dd58794993d510bacb9f3; 59ba468dcb66ec3efdc8e6a16518c5b74472a2fb; 2daed87566ba460c0988bafe85c62e24f31640eb). - UI and test stability: resolved SplashScreen test tags rename and start destination cognitive complexity fixes, merge conflict resolutions, and ignored non-working tests; ensured navigation and startup flows are resilient (commits 467982b7317d03018e07c234444d6558a7af78ef; 5f24dde63e...; 7bb79b3fc0ab6abefd1ff43199e76b6823dce66da8; ef8af3b88d3d11a7fa57da9a50e7e828395ba9d4; 1715efba4a79beb067f5214004b6ab7d7a959ff6). - Test infrastructure: fixes for test parameters and mocks; test adaptation for account deletion flows; cleanup of non-working tests (setting/test/test: c608396930142b83c0fd57f56605916dd56543c3; 125d0aac83f7a9712130b9740ca03ecdfe6ed232; 9bfbda28d0e3f957784c6b4d02d6924957b7ef30). Overall impact and accomplishments: - Stabilized core persistence and authentication flows, enabling offline-capable onboarding and reliable user state management. Increased test coverage and code quality, accelerating future feature delivery. Improved developer experience through architectural refactor and formatting discipline. Technologies/skills demonstrated: - Kotlin, Android DataStore, ViewModel patterns, and repository architecture. - Google Sign-In integration and auth service parameter management. - Firestore-backed deletion flows, test-driven development, and comprehensive test automation. - Code quality practices including ktfmt formatting and centralized constant usage.
