Jack of all trades IT-specialst as well as a strong communicator. A solid background in Embedded Software development, Full-Stack Development, deployment with Azure DevOps, Kubernetes and Data Science makes me a very useful addition to any team and a very strong solo player. Learning new concepts and frameworks gives me joy and I have a natural curiosity. Besides technical knowledge, I also have experience in process management and project management with an affinity of requirement analysis and stakeholder management.
