Senior Engineer/Consult Embedded Software C/C++

1/2020 – 12/2022

Redesign of an Existing Library. Various sensors could be connected, and the captured data could be transmitted to different cloud systems, including a proprietary cloud, AWS, and Microsoft Azure. Different transmission technologies such as Ethernet, Cellular, LoRa, and Mioty were used for data transmission. The data was always transmitted in an encrypted format.

11/2017 – 12/2019

Integration of Test Software into Vehicles and Automated Provision of Test Data for AI Developers. This involved integrating the test software into the vehicles and automating the delivery of test data to the AI developers. Additionally, Conan was introduced for dependency management, and the ROS adapter was further developed to improve integration and communication with the vehicle control systems.

1/2017 – 11/2017

Development of a Prototype for Side Impact Detection. The goal was to develop a prototype capable of detecting side impacts early enough to trigger a side airbag. This involved designing the software architecture and implementing a solution for recording and replaying sensor data in real-time. The vehicle was equipped with cameras, radar, GPS, and LiDAR. Additionally, performance optimization of the existing software was carried out to achieve a data throughput of approximately 0.7 GB/s.

6/2013 – 12/2016

Development of firmware for a product family of washing machines and tumble dryers (ranging from devices for single-family homes to commercial laundry machines with integrated payment options, remote diagnostics, etc.). Separate firmware solutions were developed for both the power section and the user interface. Additionally, a custom-developed bootloader was implemented for programming the firmware during manufacturing.

1/2011 – 3/2013

Further development of a data logger for vehicle data acquisition. The collected data was stored in the cloud via a cellular module. My task was to design and integrate a Hardware Abstraction Layer (HAL) for the vehicle data. The challenge was to design the HAL in such a way that it could be used with minimal adjustments for various vehicle types (e.g., buses, trains, trucks, etc.).
