Ik ben Xander. Ik heb een achtergrond in Mechatronica en mijn passie ligt bij het het ontwikkelen van technologie die hardware en software samenbrengt. Hoewel ik mijn studie heb afgerond in de industriële sector, merkte ik dat mijn interesse ligt bij het ontwerpen van intuïtieve gebruikerservaringen, gebruikersinterfaces en het ontwikkelen van complexe softwareoplossingen. Dankzij mijn technische achtergrond begrijp ik zowel de software- als hardwarekant, wat me helpt om oplossingen te bouwen die perfect aansluiten op industriële en digitale omgevingen.
