Projekthistorie

bis jetzt
As an IT consultant/full-stack developer, I have extensive experience in the development and implementation of customised portals and automation systems in the energy, industry and financial services sectors.
My projects range from customer portals with Angular frontend and Java microservice backend to automated document management and scalable microservice systems for big data analytics. My expertise includes frontend and backend development with a wide range of technologies such as Angular, GoLang, Spring Boot, Java/Kotlin, Node.JS, as well as the use of CI/CD tools such as GitLab, GitHub Actions, Jenkins and DevOps practices. I have experience in migrating legacy systems, developing microservices using Event-Driven Architecture with Kafka, connecting IoT devices and creating and maintaining PDF and email templates. The projects were always carried out remotely, where I made extensive use of modern software development practices such as TDD and SCRUM to deliver efficient and scalable solutions.
