Senior Embedded Software Engineer @ MuTracx

2012 - 2013
Sioux Embedded Systems
  • Developed an algorithm for the detection of circular markers in a copper substrate using C++, SSE3 and OpenMP.
  • Implemented a system for double-sided alignment of printed etch resist on copper substrates moving with six degrees of freedom that had micrometer level precision.
  • Designed various machine calibrations to detect actual mechanical tolerances that were influencing double sided print alignment.
  • Designed an algorithm for the automatic calibration of optical sensors using C++.
  • Automated the process of calibrating 9 optical units, reducing calibration time from several hours to approximately 3 minutes.
  • Designed and implemented a new system for the distribution and synchronization of commands between autonomous networked nodes, allowing for a 70% reduction in the amount of Finite State Machines and protocol messages required.
  • Designed and implemented a DSL (using XText) and code generators (using XTend) that allowed for simple interface definition and generated C++ code for middleware.
  • Created an LXC container to allow developers to have a virtualized target environment independent of their development environment.
  • Packaged all required development tools as Debian packages to allow for the easy installation of development systems.
