About

My name is Gunther Rotsch. I was born in 1965 in Germany and live now in Mellingen, a small village close-by Zurich in Switzerland.

I studied Information Science at the University of Applied Science in Mannheim, Germany. After finishing my study, I worked for a consulting company for two years. After that I worked for 10 years as a freelancer in software development projects. Then I was employed by consulting companies and software application companies. Up until 2000 I mainly developed with C ++ on Unix systems. After that my focus changed to Java Enterprise Systems.

I have been developing business applications as a lead developer or architect for 20+ years. Although my focus is on Java / Jarkata EE (full stack), I am open to other technologies such as Web, JavaScript, Python or Go.

In addition to architecture work and SOLID software design, I like to work "hands-on" in programming. I am very familiar with modern approaches such as clean coding, test-driven development and agile methods. The quality of the developed products and application of modern development processes are particularly close to my heart. This includes Static Code analysis (SonarQube), test automation, continuous integration and continuous deployment.

In the past four years, I have intensified with microservices / self-contained services, cloud-native applications (Design for Scalability, Resilience, Reliability, Monitoring), REST API Design (OpenAPI / Swagger).

I have practical experience in the deployment of containerized applications with Docker, Kubernetes and OpenShift as well as in setting up the necessary automated deployment processes. Most recently, I also have made experience with Ergon’s Web Application Firewall and roll-outs with Ansible, which complements my DevOps skills.
