Alongside my work in software development, a few earlier projects and publications remain part of my professional and personal history.
Helfrich Absinthe
I was the creator of Helfrich Absinthe, an artisanal absinthe project that is no longer active but became a distinctive part of the modern Dutch absinthe revival.
