Throughout my career I have been working in many different areas in the world of Embedded Devices. I have started as a Test Designer for production of automotive electronic devices, then switched to CMOS camera sensor drivers, development of GUI modules for a short time and finally I switched completely to Automotive sector. In the last part I have worked on: instrument panel clustersdoor controller, several projects for parking assistance systems and finally an intelligent seat heater controller. Each of the projects presented different challenges in algorithmsarchitectures, teams, designdocumentation and targets. Some were organized strictly according to the V-model, others were more on-the-go development, one of the projects for parking assistance was scrum-managed, some required heavy documentation and many of those required heavy testing. Following is a short listing with descriptions for each of the major projects (in reverse order). Some of those included working on a family of projects together with 2 or 3 small sub-projects. In order to keep the presentation better structured I have integrated them in the descriptions of the main projects. For further detailed presentation on the projects with full technical details and used tools you can take a look into my CV page.
