  • Knowledge of containerization technologies such as Docker, Podman, or Kubernetes.
  • Experience with Azure IoT solutions.
  • Familiarity with web technologies like HTML, CSS, Blazor, or Razor for UI applications.
  • Experience with Git-based version control (GitLab, GitHub, Bitbucket) and modern IDEs (Visual Studio, VS Code, JetBrains).

Benefits
