Borewit | Software Developer | Open-Source Maintainer

I build and maintain open-source libraries for music metadata parsing, playlist manipulation, audio processing, and the underlying infrastructure that supports streaming and binary data workflows. My work ranges from high-level developer-facing APIs to low-level utilities used as long-term building blocks in production systems.

A core focus of my projects is correctness, performance, and maintainability, ensuring they remain reliable over time for both individual developers and larger applications that depend on them.

JavaScript / TypeScript projects

• music-metadata
  A full-featured audio metadata parser supporting a wide range of audio formats and tagging standards, for both Node.js and browser environments.

• @music-metadata/icy
