In my role as an ECM product architect/analyst, I love to help customers in their quest to translate project requirements into existing features and future proof extensions of enterprise content management systems and portals.

To accomplish this, I can rely on my product expert knowledge for the technical part. At the same time, my experience as a functional analyst in an agile environment helps me to translate customer requirements into features that are ready to be developed.

My most relevant product expertise is with Liferay DXP, with 13 years of experience in total. I am certified in the product, give trainings, present at conferences and have been involved in more than 20 different projects for about 15 customers throughout the Benelux.

Since 2021, I have been gradually building up my knowledge on B2B commerce platforms Liferay Commerce and Kibo Commerce.


Technical Pod Lead

ACA IT-Solutions - Business unit COIN

In 2015, ACA IT-Solutions became a podular organization. Existing teams were housed in pods: business units with a unique focus in the market. As an ECM product expert I was assigned the technical pod leader role for the COIN pod. COIN stands for "Content and Information solutions" and focuses on delivering ECM based solutions based on Liferay, Alfresco and Adobe Experience Manager.

My responsibilities in this role are:

  • Safeguarding the technical quality of the projects.
  • Defining and challenging the technical strategy for the pod.
  • Bootstrapping the architecture of new projects.
  • Being the sounding board for the technical project leads.
  • Leading functional workshops with the customer for an optimal mapping of project requirements to product features.
  • Evangelizing our product portfolio and speaking at product conferences.

Liferay Product Expert

ACA IT-Solutions

I gained my first experience in Liferay projects for customers like:

  • Belgacom: partner portal, 2009-2010 (Liferay 5.2, Maven, JSF, ICEfaces, Adobe Livecyle)
  • Ewals Cargo Care: customer portal, 2011 (Liferay 5.2, Maven, JSF, ICEfaces)

  • UH Brussels: intranet, 2013 (Liferay 6.1, Maven, JSF, PrimeFaces, Spring)

In 2013, I successfully certified in Liferay at the first try with a 93% score.

Additional projects were (amongst others) for:

  • P&V Insurances: intranet + website, 2013 (Liferay 6.1, Maven, JSF, PrimeFaces, Spring)
  • Springer Nature: migration from SharePoint, 2014-2015 (Liferay 6.2, Maven, JSF, PrimeFaces, Spring)
  • Securex: customer portal, 2016-2017 (Liferay 6.2, Maven, JSF, PrimeFaces, Spring)

I also assisted in several Liferay upgrades between all major Liferay versions from versions 5.1 to DXP 7.1, such as:

  • Flemisch Government: Liferay 6.1 to 6.2, 2014
  • Springer Nature: Liferay 6.2 to DXP, 2018
  • Flemisch Government: Liferay 6.2 to DXP, 2018
  • Securex: Liferay 6.2 to DXP, 2018-2019
  • UH Leuven: Liferay DXP to DXP 7.1, 2018-2019

In 2018, the project Woningpas went live: a website where civilians can consult energy, insulation and soil related information about their home. The project is built with Liferay DXP with a team of 6 developers over 2 years (and counting). The project uses a new technology stack, in which Angular based portlets retrieve information from a microservices layer based on Spring Boot.

In the first half year of my career I gained experience in a large multinational project for BMW. Project E4N provided reliable stock management, status followup and sales of used BMWs and MINIs.

The implementation had a J2EE architecture with EJB session beans in the service layer, Hibernate for the persistence layer and Struts as MVC framework.
