About Kevin

As a Senior Project Engineer with a Master's degree in Industrial Engineering (Specialization Production Management), I bring extensive experience in mechanical and plant engineering. My core competencies lie in design with SOLIDWORKS, additive manufacturing (3D printing), and sustainable process optimization according to Six Sigma (Master Black Belt).

In my career to date, I have successfully managed complex projects, including the implementation of innovative plant concepts and sustainable technologies such as biomass heating systems (project volume approx. €2 million) and the introduction of e-mobility in production companies. I have extensive experience in additive manufacturing (3D printing), prototype development, and series production using injection molding processes, as well as in the design of aluminum extrusion profiles.

My approach is characterized by a holistic view: I sustainably optimize processes using Six Sigma methods (certified Master Black Belt), Lean Management, and REFA work organization. I utilize innovative technologies such as SOLIDWORKS Professional Mechanical Design and collaborative robotics (Universal Robots).

What particularly distinguishes me is my ability to efficiently solve complex technical challenges while always developing sustainable solutions that create long-term added value. As a certified Business Trainer and Coach, I also support teams in successfully implementing change processes.

I look forward to supporting you with your projects and implementing innovative, sustainable solutions together.
