Sander van Geloven↗ is an independent ICT consultant, mainly fulfilling the role of information analyst in his enterprise called Hellebaard↗. In his versatile work he is an avid user of and contributor to FOSS. Since the late nineties, he has actively contributed to several communities. His drive is: “What can possibly be cooler than improving the software you are working with, while optimising your work processes and have fun at the same time?” Sander's favourite projects include Python Natural Language Toolkit, Nuspell, XeTeX, Inkscape, PlantUML, F-Droid and Dutch spell and grammar checking.

FOSS spell and grammar checking was what Sander gave a talk about at FOSDEM 2016. At the NLUUG fall conference in the same year, he spoke about the English locale for the Netherlands for glibc. In 2017 at FOSDEM he presented an OFL typeface called Neude that was based on hundred year old statues and was designed with FOSS. One of the books Sander has published is on compose key sequences↗. At FOSDEM 2019, he presented the new spell checker Nuspell he co-developed. So in short, he is an all-round FOSS entrepreneur and enthusiast.
