Dennis Wagner is a seasoned managing consultant and agile transformation practitioner with 21+ years of experience bridging software engineering, product management, and organizational change. He began shipping software at 17 and has since moved from hands-on roles (architect, developer, roboticist/computer-vision researcher) to coaching leaders and teams in Agile, SAFe, LeSS, OKRs and modern product practices. As a freelancer and consultant he’s led large-scale transformations across industries—from solar inverters and IoT platforms to finance and health IT—often stepping in as interim Scrum Master, RTE or coach to unblock delivery. He pairs deep technical roots (computer graphics, SLAM/CUDA experience) with strategic fluency in topics like Beyond Budgeting, #NoEstimates and Enterprise Services Planning, enabling pragmatic solutions that scale. A frequent conference speaker, organizer and reviewer, he’s as comfortable shaping strategy with C-suite stakeholders as he is mentoring developers in TDD and software craftsmanship. Based in Hamburg, he’s known for combining real-world experience and openness to new methods to make work more fulfilling and effective.
