PROFILE

Felix Prillwitz

Worked on the librespot repository to deliver five new features over two months, focusing on backend modernization and asynchronous programming. Led a playback system overhaul by replacing Mercury with a Dealer-based messaging approach in Rust, improving playback command handling, session management, and volume control. Enhanced API compatibility by updating protobuf definitions and aligning code with evolving specifications, while modernizing infrastructure through Dockerfile and CI updates. Additionally, enabled asynchronous Avahi-based discovery by integrating futures-util and async-await macros, allowing non-blocking operations in the discovery module. Demonstrated expertise in Rust, Docker, and protocol design, with a strong emphasis on maintainability and performance.

September 2025: Librespot development focused on enabling asynchronous Avahi-based discovery and stabilizing feature gating. Delivered an async-capable Avahi discovery path by updating the avahi feature to depend on futures-util and the async-await macro in Cargo.toml, enabling non-blocking discovery in the discovery module. This work includes a bug fix to ensure the avahi feature is correctly enabled (commit a2ff3747...).
