Jeroen Baten is al ruim 30 jaar bedrijfsconsultant en specialiseert zich binnen de informatietechniek in Linux en open source software. Daarnaast was hij 10 jaar brandweerman waar hij de nodige dingen meemaakte. Hij is tevens opgeleid tot TCO-er (Team Collegiale Opvang) voor het ondersteunen van getraumatiseerde brandweercollega's.

eigenlijk probeert hij social media zoveel mogelijk te vermijden. Zijn professionele carrière is te vinden op LinkedIn, waar hij soms ook berichten plaatst over relevante onderwerpen uit zijn vakgebied. Zijn persoonlijke blog is te vinden op https://www.jeroenbaten.nl. Als hobby leest hij graag,
verzamelt hij AS/400 systemen en speelt hij graag met synthesizers en computers.
