PROFILE

Gaute Bertheussen

Gaute developed core features and infrastructure for the tidal-music/tidal-sdk-ios repository, focusing on offline content management, authentication resilience, and playback reliability. He designed and implemented a robust offline repository with concurrent download task management, FairPlay licensing, and database-backed media handling, using Swift and SQL. His work included refactoring API layers to align with OpenAPI specifications, improving error handling, and enhancing test coverage for maintainability. Gaute also improved playback startup logic in AVFoundation-based components and standardized networking timeouts for reliability. The engineering depth is reflected in his attention to concurrency, code quality, and seamless integration of backend and client-side systems.

December 2025 monthly summary for tidal-sdk-ios focusing on playback reliability and test hygiene. Delivered an Audio playback metadata handling enhancement in AVQueuePlayerWrapper and cleaned up the test suite to reduce noise and align with new high-resolution formats. Overall impact: improved user-facing playback startup consistency, more reliable quality decisions from metadata, and a leaner CI/test suite that accelerates release cycles. Technologies/skills demonstrated include AVFoundation/AVQueuePlayerWrapper, metadata-driven playback logic, Swift/Objective-C components, and test-driven/refactoring practices.

November 2025 (tidal-sdk-ios): Feature-driven enhancements to TidalAPI timeout handling, error propagation, and authentication retry, plus release hygiene. Key outcomes include standardizing URLSession timeouts (15s/30s), applying to generated code; unwrapping URLErrors in generated transport; refactoring error handling for clean transport/application separation; implementing 401 authentication retry with token refresh; and maintaining code quality through targeted reversions and regeneration workflow.

October 2025 - Tidal SDK iOS: Focused on authentication session resilience. Implemented a fix to the token refresh flow so that retryable server or network errors return stored credentials instead of failing, preserving user sessions. Client-side errors continue to trigger logout as designed. This change is captured in commit 55daae43c57b2deaaaa239c8c6888fc80862a903 and applied in tidal-music/tidal-sdk-ios. Overall impact: reduced user disruption during authentication, improved session stability, and lower potential churn. Demonstrates strong iOS client skills, secure credential handling, and robust error handling with retry logic.
