In het afgelopen jaar heb ik intensief met Reinout samengewerkt aan een innovatief programma binnen ons bedrijf. Binnen dit programma werken we met verschillende medewerkers samen aan een platform om inzicht te geven in de mobiliteit van alle Nederlanders. Vanaf het begin viel het mij op dat Reinout de drive had om er samen iets moois van te maken. Hij leerde zeer snel de technische vaardigheden die nodig waren voor de verschillende ontwikkelomgevingen die we hierbij gebruiken. Hij zet zijn tanden in de vragen die je bij hem neerlegt en in de meeste gevallen komt hij snel met een resultaat terug. Hij heeft zich de nieuwe materie en alle vaktermen snel eigen gemaakt waarmee hij te maken kreeg en stelde terechte kritische vragen. Helaas hebben wij op dit moment onvoldoende werk in onze eigen portefeuille om hem van voldoende werk te kunnen voorzien. Als dit wel het geval was geweest dan hadden wij er zeker voor gekozen om hem langere tijd aan ons te verbinden. Dus ben je op zoek naar een enthousiaste, leergierige, hardwerkende en technisch handige medewerker dan heb je aan Reinout een hele goede. Jakob Henckel Productowner – DAT.Mobility

Samen met Reinout gewerkt aan het Mobiliteitsspectrum. Hij is tijdens dit project snel gegroeid in het toepassen van PostgreSQL en PostGIS om ruimtelijke data te verwerken ten behoeve van verkeersmodellering. Hij pikt snel nieuwe dingen op door zelf op onderzoek uit te gaan en door code van collega's te reviewen. Een prettige collega om mee samen te werken.

      Bij Alliander werken we samen aan de energietransitie door het onderhouden en ontwikkelen van het energienetwerk. Voor netarchitecten programmeer ik dashboards en rekenmodellen die het energienet van nu en de toekomst inzichtelijk maken en de inpassing van grootverbruik klanten (gedeeltelijk) automatiseren.

      At Dat.Mobility I do research about public transport, car transportation, and human movements. In my current role I am programming a high resolution, data driven, maintainable, national traffic model from hundreds of gigabytes of source data that can be renewed over time. Most of the work consists of data preparation, data warehousing and mathematical modeling using PostgreSQL, Ruby, QGIS, OmniTRANS and R.

      My thesis was entitled: Tuning liquefier dynamics: A strategy for accuracy improvement in extrusion based additive manufacturing with PEEK. I gained practical experience with advanced test setups and deeply dived into the theory on working principles of a 3D printer liquefier. I modeled the behaviour and came up with a sophisticated tuning strategy that enhanced the dosing of the challenging material to the desired places considerably.

      After completing my bachelor assignment on this topic I continued working on the printer. I got a grant to improve the design. I made a new structural design with aluminium profiles, better linear guides, motor controllers, sensors and spindles and an UV projector. I helped a graduate intern with further process improvement. In the meantime I started to work on my own firmware, but due to the increased workload of my graduation assignment this was discontinued.

      As board member of the study society for Industrial Design S.G. Daedalus (University of Twente) I was responsible for public relations: I had to arrange lunch lectures, excursions, brainstorms and find advertisers. I had to raise sponsorship money and I had to guide several committees, including the Symposium Committee, Partnership Committee and the Promotion Material Committee. I have visited a lot of companies, fairs, brainstorms and network meetings and I also contacted many companies by phone and e-mail. By doing this I've learnt a lot about the value of industrial design, the implementation of design in the industry and the communication with partners and promotion of events to the students.
