Pierrick Le Gall
Pierrick was only in the Koha community for a short period of time but he made a lasting impression. With 22 patches to his name and 2021 lines of code changed he made a worthy contribution to development.
He also served as Translation Manager and briefly as QA Manager before the company he worked for stopped Koha work. The contribs.koha.org site is also run on software he wrote.
