Developer Relationship Management


Building a community of developers for GEENY the IoT Platform of Telefónica NEXT.


GEENY is the new IoT platform on the market and needs to stick out of the pile of more than 600 competitors.

Target Audience

Developers (Full stack: Frontend, Backend, Connectivity, Firmware, IoT), StartUps


Educating people in workshops and Meetups, mentoring StartUps, showing presence on conferences.

Codemash Conference – Booth

For the Codemash, a Developer Conference in Sandusky, Ohio with 2.500 developers, we planed and build a booth of 9 x 3 meters. It took place at the Kalahari Resort, a water park with a conference center.

In this unique event we wanted to educate developers on current practices, methodologies, and technology trends in a variety of platforms and development languages such as Java, .NET, Ruby, Python and PHP.

  • We wanted people to understand Geeny: What is it good for?
  • We wanted to expose the idea of Geeny.
  • We wanted developers to like/use the platform after Codemash as well.
  • We wanted to collect contacts.

We divided the area in three functional parts: a game to attract people to the booth, a discussion and a workshop area.


discuss with people

The discussion area was created to get in touch with people on a very personal level. We wanted to generate ideas and collect thoughts on IoT.


get attention

The central element of the booth was a Carrera-Track racing game meant to attract people and having a good time playing.

The top speed of the players' cars was limited by their heart rates measured with a pulse sensor. The higher the pulse, the faster the car. So we had a nice use case for connected technology.

Of course, there was a nice racing statistics screen as well.

In our workshop corner we could code with people, make LEDs blink and show them the concepts of connected products.

Racing Game details

In order to develop the idea of the connected racing game as fast as possible I decided to use a Raspberry Pi with a motor controller a colleague suggested. I equipped the racing tracks with light barriers to detect cars crossing the finishing line and connected an Arduino board with two pulse sensors and the original Carrera controllers. The software stack was just crazy. The Arduino sends the heart rate and controller information to the Raspberry Pi what adjusted the electrical power going to the racing cars. Then all the information were sent to a Java applet to project the racing statistics and show the winner. Of course the code is on Github:
