Jaap Kreijkamp has a Masters degree in Informatics (specialisation Computer Systems) from the Vrije Universiteit (VU) in Amsterdam, the Netherlands. His last year was at Linköping University, in Sweden, where he wrote his thesis.

After getting his degree he worked for three years as Campus Network Manager at the VU planning and extending the network infrastructure and developing network applications.

After having a half year break traveling through Asia Jaap moved on to Chess in Haarlem, the Netherlands. Chess is medium sized company focusing on three markets, M2M, industrial and eCommerce. Jaap worked here for four years working on several key projects as developer and/or designer.

After the birth of our first son, Luuk, Jaap started his own company, Ctrl-J, to have more control over my working hours and basically to have time for my kids.

In 2007 we made the leap to the other side and are now living in Mackay, Australia. About a year later Jaap restarted Ctrl-J, now as an Australian entity.

What have I been doing?!

Although as a freelance software developer you often get smaller projects like building websites. Having a solid education and good references from my previous jobs (good enough to be hired in by them as freelancer to continue working on several exiting projects) helped to get some more challenging projects, the main ones are listed below.
Note that several projects like Minitix and PureRouter are of evolving products and although I was for a large part responsible for the earlier versions, development is now completely transfered to the contractor.

Embedded projects:

• Linux device drivers for FIFO bus to security processor on ARM9 core based payment terminal platform (contractor: Chess-eT);
• Porting Terminal Control Environment to ARM9 core based payment terminal platform (contractor: Chess-eT).

Educational/Games:

• Development of Verkeerslokaal, in collaboration with StudioAlarm, an educational website for schools (contractor: Bureau de Groot Volker);

• Development of TuinPad, in collaboration with StudioAlarm,
  
  an educational 3D game where children learn about the effects of garden planning on animal population (contractor Stichting Omgevingseducatie Gooi, Vecht- en Eemstreek);
• Development of Vogelrijk, in collaboration with StudioAlarm, an educational 3D game about birds living in your garden (near completion, contractor: Vogelbescherming).

• Revolt, a 3D shooter for the iPhone/iPod touch I’m developing together with Kristopher Peterson (still in development).

eCommerce applications:

• Build mobile version of Minitix, a dutch micro-payment solution of Rabobank (contractor: Chess-iT);
