Hello, world!

I am Günter Obiltschnig a software engineer and entrepreneur from Carinthia, Austria.
I am the founder of the POCO C++ Libraries, the macchina.io IoT edge and fog computing toolkit, my-devices.net and the company behind all that, Applied Informatics.

What I Do

I have been programming computers since age 12. And even before I first got my hands on a real computer (a C64 my dad borrowed from a friend in 1985), I wrote my first programs using pen and paper. In my career I have programmed everything from 8-bit home computers (C64, MSX) to IBM big iron systems (COBOL and JCL, VM/CMS and CICS), various Unix systems, OpenVMS, Windows NT in its various incarnations, the Mac (classic and modern macOS), to "bare metal" embedded devices and iPhone/iPad. I have a diploma (MSc. equivalent) in Computer Science from the University of Linz, Austria.

My current main interests are embedded systems (mostly Linux-based), cross-platform C++ development, JavaScript and, foremost, the Internet of Things.

About Me

When I am not working, I spend time with my family or enjoy one of my hobbies — sailing, running, swimming, skiing, listening to or making music (drums and keyboard, and a little bit of guitar), and reading. I am also very interested in spaceflight and its history.

I also enjoy traveling. In 2012, I've lived for three wonderful summer months in the San Francisco Bay Area with my family. For most of 2013 I've lived at Lake Constance. Currently, I live with my family at the beautiful Wörthersee (Lake Wörth) near Klagenfurt, Austria.

Work

In late Summer 2004 I started working on the POCO C++ Libraries. The POCO C++ Libraries are widely used in the industry, from embedded devices to datacenter software, and from games to defense, by well-known companies such as Siemens, Schneider Electric, HP, Intel, Cisco, and many more, too many to mention here. Most of the onging development is now driven by a community on GitHub, but I still assume the project leadership role.

Based on the POCO C++ Libraries I have also designed and implemented high-level C++ frameworks like Open Service Platform and Remoting. In 2013, these, along with the V8 JavaScript engine, became the foundation of macchina.io, an open source toolkit for building IoT edge and fog computing systems.

Another product that is a direct outcome of my early IoT work is my-devices.net, which started as a secure web- and cloud-based remote access platform for embedded devices, and which is growing into a more general cloud-based IoT device management and data ingestion platform as a companion to macchina.io. macchina.io and my-devices.net are the current main focus of my work. I work for my own company, Applied Informatics Software Engineering GmbH.

Occasionally, more as a hobby, I also develop for iOS and have a couple of iPhone and iPad apps on the App Store. AIS Radar, an app visualizing ship positions received from a Wi-Fi-connected AIS device (Automatic Identification System, a widely used system for transmitting and receiving ship positions, and other data), is one example, but I have also worked on apps that help kids like my daughter understand the foundations of mathematics.

Consulting

My experience in C++ (25+ years), embedded systems development and Internet of Things system architecture, design and development, from sensor to cloud (10+ years), is available through my consulting services.

I also provide trainings and workshops for the POCO C++ Libraries and macchina.io.

Some of the services I can provide are:

  • Workshops to help you and your team get started with the POCO C++ Libraries and macchina.io. This usually includes a mix of presentations, discussions and also joint design and coding sessions specific to your project.
  • Software and system architecture and design support, with a focus on IoT and cloud-connected devices, including edge and fog computing concepts.
  • Code and design reviews, developer mentoring and trouble-shooting. I have experience rescuing failing projects by refactoring and fixing broken code bases and introducing a proper software development process.
  • C++ software development with POCO C++ Libraries and macchina.io.

Please contact me for more information and to discuss your specific requirements.
