Philips Healthcare (sept 2023 - oct 2023)
(on consultancy basis through ALTEN)
Position: Consultant
Within the Business Unit IGT, several graphically intensive clinical applications are hosted and run as virtual machines within an AWS environment. Now, there is a desire to enable these applications/VMs to run on a stand-alone system for demonstration and training purposes, as the users of these VMs are in locations where network connectivity can be an issue.
My tasks and responsibilities:
- Choosing the appropriate virtual machine technology. Which technology is suitable? Since these are graphically intensive applications, the technology must support GPU passthrough (so that the VM can directly communicate with the host GPU).
- Manually installing the respective applications on a VM created with the chosen technology to verify if the applications indeed run.
- Automating the creation of the VM and the subsequent installation of the mentioned applications.
- Documenting the installation process for the end user.

(on consultancy basis through ALTEN)
Position: Developer
Within in Business Unit IGT i worked on a cloud solution for sharing information, like images and other images, from clinical trials of medical imaging systems that are used during medical procedres. These images and files can be viewed with specific clinical (medical) applications.

Wärtsilä (mar 2018 - oct 2019)
(on consultancy basis through ALTEN)
Position: Developer
Expert Insight is a product within Wärtsilä which enables customers and engine experts to have insights in the state of their assets (ships engines and other rolling equipment of a ship) and predicts if maintenance is necessary. This should make planning and execution of maintenance easier and more cost-effective.
The product consists of a data pipeline that collects sensor data from a ship's engine. This data is then fed into a neural network which will detect possible anomalies. These anomalies are then shown in a UI in which the customer can create a case out of it. Engine experts within Wärtsilä can look at those cases and their feedback is sent back to the customer but also used as input to train the neural network.
The data pipeline consists of a number of docker based microservices which are partly developed in Java (data collection) and Python (neural network) Kafka is used for communication between the microservices and is also used for storing the raw sensor data from different data sources. The whole pipeline runs in Kubernetes in an AWS cloud environment.
I worked on the development of the data collection part and i was also involved in architectual and design decisions.

- Web application for configuration purposes (who receives which notifications) (Java 8, Play framework, Postgres).
- Mobile app for displaying the actual notifications (iOS).
The data collection pipeline and the web application are setup as dockerized microservices and run in Kubernetes in a Google cloud environment.
I was involved in the development, design and architecture and i also worked on the iOS application.

(on consultancy basis via ALTEN)
Position: Developer
CCV makes payment terminals for credit and debit cards which are used in shops and parking garages. I was involved in the development of a new payment terminal platform. This platform will support contactless payments and will be first rolled out in parking garages. The contactless cards contain a RFID chip and make it possible to pay without physically putting the card in a terminal.
The platform is based on a modified Linux kernel and a base C layer which implements low level features like security. On top of that a C# application running on Mono which implement the actual payment flow according to a standard protocol which is called CTAP.
I worked as a developer on the C# application but I also helped with testing and supported the build process by writing some Bash scripts for the build server. I was also partly involved with the design and architecture of components. An example of this is a component to retrieve version and other configuration data from a terminal.

I worked on a application which enables a service engineer to remotely:
- Upload new firmware to device, through TCP/IP.
- Monitor and configure a device, directly over the CAN bus.
As a developer I was responsible for the design and architecture of the backend as well as the frontend. The application was created with C# and WPF and was designed with a plugin architecture in mind (by using the Prism framework) As a team coach I set up the development process according to Scrum/Agile and supported other developers by sharing knowledge on technical and non-technical subjects.

Qualcomm Enterprise Services (feb 2012 - jun 2012)
(on consultancy basis via ALTEN)
Position: Developer
TrailerTracs is part of a hardware and software system that is used for fleet management. It collects data from trailers and trucks, especially temperature data, because this is mainly used in cooled trucks that transport perishable goods. The data is then stored in Omni Express which is basically a black box in the truck. This black box will then send its data to a central server which is used to monitor the truck and the driver.
In more detail TrailerTracs is a device based on a PIC processor that collects temperature data from external temperature sensors which are mounted in the truck and/or trailer. As a developer I implemented a driver in C for two types of temperature sensors. Part of this was also building support for these temperature sensors in the TrailerTracs simulator (written in C++).

UMC Sint Radboud (mei 2010 - jul 2010)
(on consultancy basis via Logica)
Position: Developer
At the UMC St Radboud hospital an in-house developed system is used for the registration and planning of administering medication to a patient, called the MEPD (Medicatie Electronisch Patientendossier, can be translated as Electronic Patient Medication System) On the ICU (Intensive Care Unit) a system called ICIP is used which does the actual administering of medication, so there was a need to integrate these systems. The challenge here was difference in data formats between the two systems, MEPD works with HL7 version 3 and ICIP works with HL7 version 2 (HL7 is a medical communication standard, see http:/www/hl7.org)
As a developer I did the fundamental design and also partly the implementation of a generic message framework that the rest of the development team could use to implement the integration between the two systems. This messaging framework was eventually used for other similar projects within the hospital.
