Curriculum Vitae

Professional ​Info​

I am a embedded software engineer and computer scientist. My expertise reaches from assembler for microcontrollers (e.g. Arduino or Atmel) up to model-driven development with Java or C++. In my spare time, I add new features to Hyperion, write games for retro gaming consoles (Atari VCS, Amiga, Game Boy) and try to solve IT security challenges. I am a team player, always interested in new business opportunities and accustomed to work in deadline-driven environments.

Finished Projects

  • Implementation of a test framework for an embedded system which controls lighting installations. It runs Linux and provides a REST interface. The interface is accessed by a smartphone app which allows users to dim lights, program a timer, etc.

    Tools and Technologies: Android, Java, REST, DALI-Bus, Linux, Espresso

  • Development of a smartphone app for a powerbank sharing system. A user with low power can rent and return a powerbank in restaurants, airports, etc. The smartphone app contains a map, a QR code scanner and payment functionality.

    Tools and Technologies: Android, Java, Cordova, Camera Autofocus

  • Building an infotainment system for a car which consists of several touch displays and allows the integration of a smartphone using wireless technology. During the project, a first stage boot loader and a Linux kernel driver were written. The kernel driver controls a display deserializer chip.

    Tools and Technologies: C++, ARM Assembler, Linux Kernel, Apple CarPlay, Android Auto, TCP, Renesas „System on Chip“

  • Implementation of a camera application with Java which adds graphical overlays in real-time to a H264 video stream. A patent was submitted to protect the technology.

    Tools and Technologies: Java, Android Studio, Git, OpenGL, Patents

  • Implementation of a RTMP library for Android. It allows Android-Apps to stream video/audio content to services like Twitch or Ustream. Therefore, an x86 Linux library had to be crosscompiled for Android ARM architecture.

    Tools and Technologies: C/C++, Git, GDB, Android Native Development Kit, RTMP, Wireshark

  • Design of an android-based, embedded camera system for cars which records the driving experience and allows an analysis for quality assurance. It reads data from an image sensor, processes the resulting video with a H264 encoder, stores the result in a SD card or streams via a network interface.

    Tools and Technologies: C/C++, OMAP4 Processor from Texas Instruments, GDB, Git, MS Visio, Android Studio, Linux Kernel, RTP Protocol, Wireshark

  • Implementation of an ultrasound-based system using Java which monitors workers and automatically detects failures in their assembly process.

    Tools and Technologies: Java, UML, Xtext, Finite State Machines, Google Web Toolkit, XML

  • Controlling a photovoltaic module with a raspberry pi. The system measures power consumtion and adjusts maximum power rating (Pmax). The core of this system is a modified C library.

    Tools and Technologies: Linux für Raspberry-Pi, SSH, Serial Interface, Yasdi

  • Implementation of a runtime packer which encrypts windows portable executables (PE). This approach protects binary files against reverse engineering. The runtime packer was developed with x86 assembler and contains a Windows PE loader and a AES decryption stub.

    Tools and Technologies: x86 Assembler, C/C++, Visual Studio. Win32 APIs, Windows System Programming
