I debugged issues with a Bluetooth Low Energy (BLE) based communications link between a firmware written in C++ running on bare metal ARM hardware and an external closed-source/black-box device. I extended the real-time firmware with new features and created technical documentation. I also worked on tooling written in Python to support production level configuration.

I reviewed changes to an Embedded Linux firmware to debug issues with a kernel driver. I implemented an alternative user space based solution in C with improved performance and portability as well as reduced maintenance effort.

I designed and developed application code using C and Lua, which runs as part of an Embedded Linux based firmware. For that I set up development and test environments using Docker Compose. I reviewed and implemented application logic according to several EEBus specifications. Related to that I also provided support for the requirements engineering team. Furthermore I performed networking related analyses as well as work on Linux driver and hardware debugging. I also reviewed and debugged Go and Python programs. Additionally I wrote POSIX compatible shell scripts and extended a Yocto project with new recipes. I also devised and specified test cases as well as API and requirements specifications.
