About me

Jan Willem Groenenberg

Welcome to my page. My online world on the internet, where many people know me as JeeWeetje. But you may also call me Jan Willem Groenenberg.

As IoT Integration Architect at Atos, I work in the field of cloud and Internet of Things (IoT) where I try to accomplish innovative solutions for the manufacturing and transportation markets. The solutions I work on are often build using Microsoft technologies like Azure IoT platform and the Azure IoT Edge.

With more than 15 years of experience in web development (I earned my dinosaur badge with pride) it was 2014 that I was in the need for something new. Via a short route in mobile app development I added ‘Internet of Things’ to my interest and field of work. And I love it till today.

I like to share my knowledge with others. That is why I am a public speaker at Atos (Atos Experts Community) and several user groups (Azure IoT Community, SDN and dotNed) and events (Experts Live, Codecamp Romania, Future Tech, Microsoft TechDays, IoT Tech Days and Dev Nation) in the Netherlands and abroad.

I also share feedback as an active Windows Insider and a member of the Azure Advisory Board.

Besides being a geek, I am also a husband, a dad of a girl and a boy, an owner of an English Cocker Spaniel, a foodie, a former Coca Cola junkie (trying to go going cold turkey), a recreational trail runner, a snowboarder, a hobby chef, and gadgets freak.

In 2013, I have been diagnosed as an autistic with Asperger syndrome, which gave helpful insights about the origin of my weaknesses and strengths.

Want to know more? Just ask, I might tell you more…


I, JeeWeetje, the author of the content that can be found here within, can assure you, the reader that any of the opinions expressed here are my own and are a result of the way in which my highly disorganized and somewhat dysfunctional mind interprets a particular situation and or concept. Because I have Asperger syndrome my opinions and observations can be different than those from “normal” people. The usefulness of any type of information on this site is a matter of your opinion. I shared it, it is up to you to do something with it. Reading or skipping it are the blue and red pill options at hand at any time.

To make sure my current employer, Atos, stays out of, hopefully never happening, future legal charges I hereby guarantee that the only connection with this site is the fact Atos is my employer and I occasionally write about my work. At least the parts that are not covered by NDAs (No Disclosure Agreements). If you seek for Atos company secrets here, you might be better of in a dark alley looking for that mysterious guy in a raincoat. It is my work that pays the mortgage, not this site.

I would like to expressly convey to you (the still reading reader) that were I to accidentally defame, purge, humiliate and or hurt someone’s person or feelings as a result of them reading and or acting upon any or all of the information and or advice found here at my site, it is entirely unintentional of me to do so.

Any comments that may be found here at, jeeweetje.netrunninggeek.nl or pomtiedom.com are the express opinions and or the property of their individual authors. Therefore, I the owner/author of this site can not be held responsible for the fact that the minds of the respected authors may just well be as dysfunctional as my own. If not more….

And it is not a practice of my own, let alone I have the time for it, to edit any comments left here by others (like you, regretting that last comment).

Should you (the hurt reader, reading how to handle me, the brute) identify any such content that is harmful, malicious, sensitive or unnecessary, I request that you contact me so I may rectify the problem. Failing that you may like to just sit and weep incessantly! Please do note; I do not offer hankies if you just sit and weep incessantly.

In the case of any legal issue, contact me first and please don’t sue me instantly! I, as a Dutch citizen, try to respect Dutch laws, copyrights and intellectual properties of rightful owners. If I fail to do so, I did it by mistake.

Privacy Statement

For commenting I require you (the comment giving reader, in fact, a writer) to give a name and an email address. That is only for identifying yourself on this site and for me being able to contact you if needed. I do not harvest email addresses for mailing lists or to fill your inbox with spam.

Technical protocols told the easy way; Your IP address is known by this site. You (the visitor, hopefully reading and commenting) know the IP address of this site (most likely by a more meaningful alias, like the domain name). Both IP addresses are needed to be able to communicate, nothing more.

Everybody needs cookies. The tastefulness of cookies is a matter of personal taste. I do my best to only serve the most tasteful cookies in order to keep you happy.

Selling or sharing with third parties of the above-mentioned data would give me a revenue not even near to the wages of my daytime job. So there is no reason to do it.

But above all, be aware that anything you share on the internet might be publicly available to a certain degree. Safeguard your privacy, please.

If you made it to here, reading all of the above, you earned my instant respect.
