Commercial Product Manager @Deutsche Telekom

Berlin, DE

Following the successful development of the API Portal at hubraum, I was recruited to join Deutsche Telekom\'s Group-level API initiative. As part of the API Product Team, I now lead the strategic development of the Group API Portal (developer.telekom.com)—our central platform for exposing Network APIs and CPaaS APIs to partners, developers, and enterprises.My responsibilities go far beyond platform management: I drive usability and SEO optimization, ensure seamless integration into Deutsche Telekom’s new BSS stack for APIs, and develop innovative, value-driven solutions based on our existing product portfolio. Together with external partners, I actively co-create new offerings along entire industry value chains—ranging from retail and insurance to customer service and support. My focus is on building real business impact through scalable, future-ready API solutions that meet market needs and accelerate digital transformation.This is just the beginning—over the next two years, we expect significant advancements in this domain and offering, pushing the boundaries of what’s possible with our API ecosystem.
