Speaker Details

Pieter-Jan Drouillon

With more than 15 years in the IT sector, I have built my expertise around the following three key pillars: java development, data and education. As a coach and lifelong learner, I have a natural curiosity to understand the challenges and create better solutions. Following this mindset, I have recently finished Magna Cum Laude the Postgraduate in Big Data and Analytics in Business at KU Leuven, pursuing a better understanding of the challenges faced in the sector.


In my spare time, I spend time with one partner, two kids and four guitars. If time permits, I also like to try out new technologies on pet projects.I'm a member of Toastmasters Leuven, a club where you can improve your speaking and leadership skills. So far I've completed the competent communicator manual, containing 10 speeches each focussing on one essential part of public speaking. Currently I'm working on 'technical presentations', one of the many advanced manuals. I occasionally won the best speech of the evening at our meetings which is quite the accomplishment given the high level of the experienced club members.


So far I have presented some educational papers on international conferences and presented at meetups (eg. https://www.meetup.com/AEM-Developer-Meetup-BE/events/238245647/ and https://www.meetup.com/AEM-Developer-Meetup/events/248690741/).  This last talk was well received at the Leuven Big Data Meetup.


My most recent speaking experience so far was at Devoxx Poland 2021 - my first time speaking at a big Java conference.



No more John Doe: realistic mock data with mockaroo
Tools-in-Action (BEGINNER level)
Room 9

When working on something new, you often have to create fake data. Those attempts usually never exceed the John Doe or test123 level, and that’s fine. If you need more meaningful information, or have to generate data on more than one occasion, then you need a tool - welcome mockaroo!


Mockaroo offers a wide range of generators, ranging from IT (domain names, IP addresses, email) over commerce (currencies, IBAN) to miscellaneous (colors, animals, currencies). On top it provides an intuitive UI to get you started. Next to that, you can save your data in common formats.


In this session, I’ll briefly cover why realistic data is useful. Next I’ll dive into mockaroo and how to create your realistic dataset. While doing so, I’ll provide practical tips based on previous experiences. A short demo consuming this test data as an API will conclude this talk.
