MDAbout Matei
I build systems that turn complexity into clarity - both in data and in teams.
With 8+ years in the Big Data field, I’ve led teams and built cloud-based data platforms that help medium and large companies make sense of their data. My focus is on scalable, efficient data architecture and integration.
Beyond the technical work, I’m deeply invested in personal growth. I’m part of a leadership group, have completed coaching and communication trainings, and explore psychology through Jungian therapy. These experiences shape how I lead - with clarity, presence, and purpose.
