• Designed hardware, firmware, software and enclosures for wearables and sensor-networks. An example is the OpenSmartwatch project, built using commonly known microcontrollers (ESP8266, ESP32) and software frameworks (RTOS, Arduino, PlatformIO). • Reached a large audience on social media, teaching about electronics, 3D printing and software development• The project has grown to dozens of contributors and has received more than 800⭐️ on GitHub.

• Conceptualized and implemented a customer-specific, on-premise integration of the LANCOM Management Cloud (LMC). Designed the system-architecture and APIs.• Enabled the migration of a legacy system to a state-of-the-art, scalable architecture.

• Designed and implemented the successor of ElsterRules with web-based technologies. • ElsterRules is an Eclipse RCP based tool which uses a domain-specific language (dsl) to generate source code for validation of user input in (tax) forms across multiple platforms in the ELSTER project. • Drove the adoption of the A12 platform to establish enterprise low code in practice.

• Design and customisation of system architecture for international data science projects. • Supervised international software development teams using agile methods. • Improved productivity of researchers through automatic storage, archival and retrieval of scientific data on instruments with limited resources.

• Implemented web-based, network device management solutions. • Maintained and developed the LANCOM Large Scale Rollout & Management (LSR) • Designed the system architecture of the LANCOM Management Cloud (LMC), the successor of the LSR, building up the core competences and teams for cloud development at LANCOM.
