Hi, I’m Flavius Cojocariu, Senior Engineering Manager and Platform Architect based in Munich.
Leading Teams. Modernizing Platforms. Enabling Engineering Excellence.
About me
Hello there!
I’m Flavius Cojocariu, a Senior Engineering Manager based in Munich, Germany. I lead two platform teams at IU Group — Germany’s largest university — owning the technical direction for student-facing platforms serving over 100,000 users. My work spans platform architecture, team building, and engineering strategy.
With 13+ years in software engineering and 5+ years in engineering leadership, I’ve built teams from scratch, driven monolith-to-microservices migrations, introduced observability and DORA-aligned practices, and designed data architectures across organizational boundaries. I operate at the intersection of hands-on technical depth and organizational leadership.
I work alongside Heads of Engineering and Directors on cross-company data strategy, and I’ve been selected for task forces that shape how data flows across pre-sales, sales, and post-sales. My peer group is HoEs and Directors — I contribute to quarterly alignment on cross-platform strategy, team structure, and organizational planning.
Beyond my full-time role, I help growing tech companies modernize their platform architecture and scale their engineering teams. If you’re a Mittelstand company or scale-up navigating a platform transition, a team scaling challenge, or an architecture decision — I can help.
I’m always open to conversations about engineering leadership, platform architecture, or potential collaborations.
Let’s build something that lasts.
