As a Product Engineer at MATTR, Ralf works to turn digital identity technology into solutions for real-world problems. Helping organisations put this technology into production, he sees firsthand where the standards meet reality. Open standards and interoperability sit at the core of his work, and he actively contributes to the development of the digital identity standards that make these systems trustworthy and able to work together. Through both implementation and standardisation, Ralf helps build a trusted, interoperable identity ecosystem for Aotearoa and beyond.
