I'm a TPM with long involvement in open source. I make my living working on Magma for OSPOCO. My most recent contributions, big or small, paid or unpaid, were to OWASP, fbjs, Storybook, XSPF, CHAOSS, Merico Build, and The COVID Tracking Project. I'm also contributing to the Metadata for Music NFTs WG.
In my private life I make music, and since a lot of it is in the public domain I post my transcriptions on Github using open formats like Lilypond and Musescore.
