Senior🎓
Top SchoolAndré Sonntag is a results-driven software engineering leader with nine years of experience, currently managing Digital Services & Software Engineering at UNITY Consulting & Innovation in Frankfurt. He blends hands-on technical depth—ranging from static analysis tooling and secure software engineering to PLM and artifact management—with a strong track record in architecture, agile delivery, and stakeholder-aligned roadmapping. His background in applied research (Fraunhofer, Heinz Nixdorf Institut) gives him a rigorously evidence-based approach to tooling and security, while his consulting roles demonstrate an ability to translate that research into industrial solutions. Known for driving vendor selection, technical strategy, and cross-functional coordination, he excels at making complex engineering decisions practical and repeatable. Despite a consulting focus, he retains developer instincts from early Java and full‑stack projects, enabling credible technical leadership across the stack.
