Currently

  • SpoolTesting a Windows build alongside the macOS releases.

  • FLUXStarting the study set out in my proposal: how a music model should develop a musician's own draft, and what musicians take from it.

  • MemoHeadRebuilding the prototype as a personal voice archive that aims to keep only my own speech, starting with local speech recognition.

  • Applying to US master's programs for Fall 2027.
