Alex en ik hebben mogen samenwerken op een kritisch en voor ons beiden erg lastig project dat te maken heeft met compliance en informatiebeveiliging. Dit hebben wij met succes mogen afronden, met grote dank aan Alex zijn inzet. Door Alex zijn on-uitputtende enthousiasme, leergierigheid en vriendelijkheid is hij een erg betrouwbare en fijne collega om mee samen te werken.

Everyone has a person / colleague they go to when they need more (technical) information. Alexander is that person for me. His broad knowledge about IT never fails me. He easily translates business issues into IT solutions that is relatable and understandable for all stakeholders. And a genuine teamplayer.
