Summary
🤩
RockstarHans-Jörg Merk is a seasoned technologist with 12 years of software experience and a long career in telecommunications, now living in Jüchen and working as a Privatier. He has a strong track record as a backend developer in open-source smart home projects—contributing WeMo, IntesisBox and MiLight/Energenie bindings to notable projects such as Eclipse SmartHome and openHAB, including adding power-measurement support and improving discovery and control logic. His background in Telekom spans hands-on technical roles to account and service management, giving him a rare blend of field-level telecom expertise and pragmatic software engineering. Comfortable working with UPnP, SOAP and device integration patterns, he focuses on reliable device interoperability rather than flashy front-ends. Colleagues would note his steady, detail-oriented approach to maintaining and refactoring legacy Java bindings to modern styles.
