Alexander Lehn

Alexander is the CTO of 3m5. and has been shaping the company's technical direction for over two decades — making him one of the longest-serving team members since the early days of the Dresden-based agency. With deep expertise in building mission-critical web applications for major enterprises in insurance, media, and beyond, he knows firsthand what it takes to keep complex systems running reliably at scale. At Neos Con, Alexander hosts the panel discussion "Cutting Edge – Neos in Mission-Critical Applications", bringing together practitioners who push Neos into demanding real-world scenarios. When he's not architecting software, Alexander trains for Ironman triathlons — proof that his endurance extends well beyond long-running deployments.
