About

Hi and welcome, my name is Zoltan Mizsei.

With 16 years of experience working with CAD systems - especially in CATIA automation - I’ve built deep expertise in optimizing design workflows and driving engineering efficiency.

Currently, I work as a Senior Development Lead Engineer at Segula Technologies Experts AG in Stuttgart. I focus on maximizing time and resource savings through knowledge reuse, parametric modeling, scripting, and PDM-friendly automation. I’m also deeply involved in motion simulation, using either the DMU Kinematics module or skeleton-based approaches, depending on the project. My design philosophy centers on clear, logical, and maintainable model structures. I stay curious, always exploring new methods and smarter solutions.

I’m particularly passionate about bringing in ideas and tools from other industry segments - such as automation strategies, version control systems, and IT-based workflows - and adapting them to the CAD and engineering environment. This cross-pollination often results in smarter, more scalable solutions and gives me a fresh perspective on tackling daily challenges.

My wide-ranging technical interests often give me an edge - whether it’s geometry, IT, logic, or hands-on problem-solving, I enjoy tackling complex challenges. I stay up to speed with emerging technologies and enjoy weaving them into my workflow. In recent years, I’ve also written training materials, mentored colleagues, and developed leadership skills through team coordination and process planning.

Through both my work and personal passions, I maintain strong international connections and thrive in multicultural environments. I’m open, collaborative, and motivated by seeing innovative results come to life through teamwork and support.

While my current projects are rooted in the automotive industry, I spend my free time coding for microcontrollers, managing websites, and translating books - because curiosity and creativity go hand in hand.
