Freelance Software Engineer

Development of a secure embedded operating system (RTOS, ARM Cortex-M3, C251) for products like IP-Protection, digital passports and TPMs

• Implemented cryptographic algorithms, according to ISO/NIST/FIPS/IEEE/IETF standards (including secure coding and optimization)
• Developed integration and unit tests
• Designed controller specific security concepts Introduced an XML based hierarchical configuration system
• Extended CMake with a generator for KEIL μVision projects
• Introduced CMake as build system
• Redesigned the build, test and release ecosystem Developed highly customized automated code analysis, using libclang
• Redesigned the CI/CD workflow with Jenkins Pipelines (migration from Jenkins Build Flow)
• Supported FIPS and Common Criteria certification audits
• Implemented automated documentation generation for doxygen documentations

Test Framework for Embedded Systems

• Ported a custom MSTest/NUnit based test framework to xUnit.net
• Developed a customized xUnit.net test runner Extended xUnit.net for automated, configuration aware generation of test cases

Trusted Platform Module (TPM)

• Adapted multiple modules to FIPS certification requirements
• Redesigned a cross-platform tool for TPMs (Linux, Windows, DOS, UEFI)

Vehicle-to-everything communication (V2X)

• Implemented cryptographic algorithms for the communication protocols

Java Card

• Implemented native side of cryptographic Java Card modules

Software development for the in-house simulation tool for complex systems like road networks, water systems or gas turbine power stations.

• Implemented the server backend (C#, ASP.NET, WCF) for a road network simulation with Google Maps frontend
• Redesigned the client-server architecture of the simulation tool, using WCF instead of .NET remoting
• Developed Software Development Kits (Installer, Visual Studio Extensions)
• Migrated a mathematical library from Compaq Visual Fortran 6 to Intel Visual Fortran 12
• Developed a software tool for the visualization of simulation results (2D/3D)
