  Summary of Experience: - Developed and maintain multiple open-source projects on GitHub. - Created a declarative programming paradigm named 'dclare', implemented for Java and Jetbrains MPS. - Utilized 'dclare' to build a decision support workbench, CDM, for clinical environments. - Actively working on enhancing decision support tools for doctors in hospitals. - Co-founded "Open Walnoot," a company focused on activities in the clinical field, in collaboration with "We Are Not." Belastingdienst (Dutch Tax Office): - Contributed to the design and development of an agile new tax handling meta automation environment. - Utilized Jetbrains MPS to enable tax experts to input law rules, which are then compiled into Java code for running as a calculation services. - Spearheaded the creation of a Continuous Integration (CI) environment using Jenkins, integrating various plugins and writing bash scripts for seamless operation. - Designed a highly efficient system for nightly testing of tens of millions of tax declaration cases in a heavily multiprocessor Linux environment, employing UDP and services. - Implemented a web dashboard to display test results for management's convenience. - Extensive experience with java/MPS/git/CI/linux/bash - Expanded the system's usage beyond income tax calculations to cover 50+ different tax areas. EBPI: - Led the design and development of a workbench dedicated to Taxonomy creation and maintenance. SystemizeIT-UK/ChurchMutual-USA (workbench for insurance designers): - Designed and developed an Eclipse-based workbench with a central (CDO) server and multiple clients. - Established an automated build environment from scratch on the Amazon cloud, using Jenkins and SVN, with integrated testing (guidancer) and a delivery website. - Managed Linux machines with Windows satellites for specific tests. - Proficiently employed shell scripting and Java coding throughout the project.

  Freelancing in the area of Java/MDA/embedded. Customers/project: === SystemizeIT-UK/ChurchMutual-USA (workbench for insurance designers) Designing and developing an eclipse based workbench with a central (CDO) server and many clients. Setting up an automatic build environment (jenkins/svn/...) from scratch on the Amazon cloud with automatic testing (guidancer) and an integrated delivery website. This software factory runs on linux machines with windows satellites for some tests. It involves a lot of shell scripting and java coding. === belastingdienst (dutch tax organisation) (MDA/C#/Java) Help design and implement a model based generation system for handling of tax rules. Setting up a large build environment (jenkins) on a local virtualized cloud. Designing a large test cloud for continuous testing. Making a C# test tool for meta level debugging of the generated source code. The software factory is windows based and involves a lot of DOS scripting as well as java and C# coding. === Sound Intelligence (agression detection through sound analysis) Porting C code for audio analysis to DSP cores. Maintaining and extending the build environment. === Aduna (RDF store software for websites) Making drivers for an RDF store, implemented in java using several open source packages. Research: As an (unpaid) research project I work on Dclare within the Modeling Value Group. Dclare is a declarative language we like to use for defining software factories (and more!) in a safer and compacter way. Show less
