Profile
I am a highly motivated individual, someone who enjoys exploring
new technology and applying the knowledge gained in new and exciting
ways. My strongest point is my knowledge of the UNIX/Linux system
environment with strong administration skills as well as knowledge
of the systems themselves. C++ and Python are currently the two
programming languages I know best, like any good programmer I am
easily able to master new programming languages. I've worked with
customers on many different projects and helped solve difficult
problems they were facing. Other interests include electronics
(hardware engineering), embedded systems and network security.
I am knowledgeable in writing secure software that doesn't contain
common pitfalls that lead to vulnerable software.

Projects
These are the projects I am currently involved in, or have been involved in.
Near Space
As a team of 15 students we developed a near space pay-load along
with the various science experiments. With a GPS device TNC and a
HAM radio on-board we were able to track the near space pay-load
using APRS data that was being sent back. After retrieving the
pay-load we were able to retrieve the science data along with the
pictures that we had taken with a still camera.
Open Source
I am a big proponent and supporter of Open Source software, a lot
of the software I've written is available for free from my Github page located at https://github.com/bertjwregeer/.
This includes my most recent samples of code.
