    My role in HEDNO is to deliver software solutions and implement data management processes, acting within interdisciplinary teams that conduct projects from realization to operation. Meter data management is the area where most of my time has been devoted, especially in telemetering data collection, processing, validation, and dissemination.

Equally fascinating have been applications that serve user-oriented workflows, where interfaces for the communication between people and software demand perpetual care and improvement.
