Hello, my name is Rainer Poisel.
I specialize in making development processes in the embedded software industry more efficient, scalable, and secure. With deep expertise in DevSecOps, Continuous Integration and Delivery, software development, and process automation, I help companies optimize their product development and future-proof their workflows.
My knowledge of safety- and security-critical applications (e.g., IEC 62443, Cyber Resilience Act), along with expertise in modern processes and technologies such as GitOps, containerization, and contemporary programming languages, enables me to craft tailored solutions. I also focus on modernizing legacy technologies, including older C/C++ applications, ensuring both operational security and protection against threats, while fostering innovation and reducing costs.
Whether it’s analyzing and modernizing existing processes, building new CI/CD pipelines, or providing targeted training, I focus on delivering sustainable, measurable results. My approach is pragmatic, cost-effective, and designed to empower teams, minimize risks, and drive long-term success.
