UNIX enthusiast · Open-source developer · AUR packager · Spaced repetition nerd
I am an open-source developer with a strong focus on the FreeBSD/OpenZFS ecosystem, Arch Linux packaging, and self-hosted infrastructure. I maintain several AUR packages, have published an R package on CRAN, and actively contribute to upstream projects in the UNIX and spaced repetition space. Alongside my development work, I build EDC database systems for clinical research — self-hosted alternatives to commercial platforms like REDCap.
