Since 2000, at a age of 12, I have been developing software. I started building and publishing websites on the internet. Soon thereafter other hobby projects followed and I started contributing to open-source software. Initially I used ASP (classic) and after that switched to PHP. Starting in 2004 I also began publishing articles and tutorials related to software development. My first article was published on SitePoint (TrackBack To The Future: Next Generation Content Referencing) and many more followed.
In 2006 I took a gap-year and worked full-time on several of my own web-projects, which provided an income primarily based on advertisements. At this time I had a broad portfolio of varying web-projects targeting different audiences. Several web-projects were related to software development, primarily about ASP (classic) and PHP.
After this gap-year I started studying at the University of Twente. The undergraduate study (BSc) Business & IT was a very good combination between computer science and business management. Soon after starting at the university I started as a software engineer, whereby workweeks of 24+ hours were not an exception. In addition to developing software, my role was generally much broader at this time which required additional skills, such as requirements analysis, user support, etc.
After finishing my Bachelor's Degree I started with the Computer Science graduate study (MSc). During this time I did an internship at Topicus I&I, after which I worked there several months to implement the results of my internship in production. I finished my Master's Degree by writing my final thesis at the Databases Group of the University of Twente. After obtaining my MSc I started working full-time as a software engineer.
Since november 2018 I have started working as a freelance software engineer. In the past 15 years I have built up a broad set of skills and experience in the area of software engineering.
At NS Zakelijk (part of the Dutch Railways) I was part of the Business Platform team. We were responsible for the support, ops and development of all business web-applications for the business customers of NS. These involved multiple web-applications, with the primary focus on the Mijn NS Zakelijk portal.
Technologies used included Java11/17/21, Wicket framework, Spring Boot, AWS services (e.g. CDK, Lambda, Fargate, CloudWatch, etc), Oracle, PostgreSQL, Angular and various developer tooling (i.e. Azure DevOps, Maven, etc).
Close experienceAt the Belastingdienst (Dutch Tax Office) I work at the "Schenk- en Erfbelasting" division, as part of a serviceteam supporting multiple applications in the area of inheritance and gift tax. The team's primary focus is on improving process- and productquality of the various applications.
Technologies we use include JavaEE, Angular, DB2, WebSphere, JMS en Splunk.
Close experienceAs a software engineer at Topicus I primarily focused on (big) data processing, data transformation and business intelligence. Primary tasks included:
During my work as Software Engineer at the Databases Group of the University of Twente I was part of a valorisation project related to Workpackage 6 of the TimeTrails project of the COMMIT/ research community. Tangible results were: existing technology ported to MonetDB with improved query performance, created an ETL based on Hadoop/MapReduce for distributed index creation, developed tooling for the technology and other minor improvements.
Close experienceDuring an internship at Topicus I&I (a business unit focused on business intelligence) I researched new possibilities for an analytical database to be implemented within their custom BI application.
After that I worked few months at Topicus I&mpt;I to implement MonetDB into their architecture as a new analytics database.
Close experienceDuring my study I was a freelance software engineer, contracted via UniPartner Twente. This is a student consultancy company and matches companies with studies. I did several development contracts through them, among others for TNO.
Close experienceResponsible for the information system of Twente Academy. Initially developed a new solution based on PHP/MySQL and migrated away from an MS Access solution. In the years following the initial development continuously supported and extended the system.
Close experienceFor the S&O department of the University of Twente I did a temp assignment to develop the new website of the Student Career Services. This was implementen using the custom CMS of the University.
Close experienceAs a software engineer at Service2Media I was part of the team that developed mobile web-appplications for various large customers, such as KPN and CNN.
