What I'm looking for

I seek a data-focused role where I can lead automation and infrastructure analytics, mentor teams, and deliver actionable insights in a collaborative, innovation-driven environment.

I am an experienced data scientist with extensive knowledge of the telecommunications industry, currently serving as Data Scientist III at Deutsche Telekom Technik GmbH, responsible for technical and organisational ownership of FTTH rollout models and presenting results to management and stakeholders.

I lead a technical team of nine, mentor new hires, participate in hiring, and drive international projects and knowledge transfer while developing data-driven processes, automation and database interfaces using Oracle/Linux environments.

I hold an M.Sc. in Big Data & Business Analytics (grade 1.2) and a B.Sc. in Business Information Systems (grade 1.7), and I work with Python, SQL, Linux, Git, VBA, KNIME and geographic visualisation tools to create meaningful reports and visualisations that support decision-making.
