Career Objective: Provide solutions as a Software Architect / Senior Developer to technical challenges in the real-time control, embedded or IoT software industry.

2019 - present Sr. Solution Architect
Aicas LLC, Karlsruhe, Germany
Architecture and technical director of customer solutions for embedded/realtime applications, supporting senior executives in crucial phases of business development
promotion/evangelism of company-designed products and methods in executive sales conversations
created and drove implementation of show-floor demonstrations at CES, AWS re:invent, AutoTech Detroit, IAA Munich in concert with external companies such as NXP, DMI, AWS
re-architected and drove re-implementation of AWS Fleetwise for automotive targets, made AWS Greengrass realtime capable
designed and implemented no-code solution for integrating arbitrary embedded systems with the Sparkplug cloud protocol
2012 - 2019 Software Architect, Sr. Staff Software Engineer
Lam Research Corp., Fremont, CA (Semiconductor Equipment Manufacturer, S&P500, NASDAQ:LRCX)
Novellus Systems was acquired by Lam Research, and I was part of the transition evaluation team assisting software management in fact finding/decision making regarding merging of the two software organizations and their utilized technologies. In addition, I designed and implemented various components to create integrations for the three Software Control systems in use, primarily on the realtime control side, including:
Software development of several hardware control systems using EtherCAT running on WindRiver vxWorks. The systems implemented a hard realtime script engine based on an vendor specific protocol; embedded C/C++ and SmallTalk
Development of High-Speed Data Acquisition system connecting different field bus types to the data storage system, implemented in C++ and Java
Bridging SmallTalk based control system to more modern systems using MQTT + Java applications
2000 - 2012 Software Architect
Novellus Systems Inc. San Jose, CA (Semiconductor Equipment Manufacturer, S&P500, NASDAQ:NVLS)
Principal architect of the next generation, distributed equipment control framework for the entire product line of the company.

This distributed framework uses several types of Java/JVM's, including Embedded/RT-Java.
Objectives for the control side was emphasis on high reliability and scalability, but also had to enable easy integration of a large variety of motion controllers and process control devices in an easily extensible manner.
The data acquisition side needed a highly scalable data transmission and storage system for 1MM+ I/O updates/second. In addition, objectives was enabling integration of external software components and libraries into finished end-user applications.
I was responsible for the software architecture and the technical leadership in this $12+ Million, 50+ man year project, being used in production since 2007.
Along with the system architecture, I was in charge of the design and partial implementation of the realtime control components, I/O interface, configuration management, factory interface, SEMI Interface A development, data acquisition, wafer sequencing, etc.
