ABOUT CHRISTIAN BAHLS
ML Engineer / Technical Lead with background in applied mathematics (PhD), policy consulting, and change management. I build systems that ship fast and get repeat business. Currently: Principal AI Engineer at PLANET AI GmbH. Built platform architecture enabling rapid solution development, short development cycles, fast prototyping. Document processing pipelines for fast ingestion, domain-specific Q/A, and automated aggregated insights. Multiple deployments including field technician support tools. Repeat business validates the approach. Past: Head of Software Development, benntec Systemtechnik GmbH (Rheinmetall Group). Led turnaround and change management across four development teams. Encouraged ownership culture. Delivered under pressure: core system modernization, new web framework, learning platform from greenfield to production. Before that: Group Leader at German Aerospace Center (DLR e.V.). Traffic situation systems using sensor fusion, stochastic methods and machine learning. Anomaly detection, autonomous vessel movement planning. Project lead across intermodal transport, maritime emissions, safety/security.🧩 Core Competencies:* Software Development: Full-cycle engineering leadership and technical implementation* AI and Machine Learning: Transformer architectures, CNNs, RNNs, SVMs, differentiable programming* Applied Mathematics: Constrained and unconstrained optimization, uncertainty quantification, dynamical systems (ODEs, PDEs and SDEs)* Policy Consulting: Political advisory, government relations, political communication Board Member and Political Advisor, MOGiS e.V, children\'s rights and advocacy for victims of violence.
