• Hands-on expertise with cloud platforms (AWS or Azure), delivering scalable, secure and well-architected solutions.
• Familiarity with CI/CD tools such as Jenkins and/or Terraform.

Desirable Skills:

• Experience working in a consultancy environment, engaging with external stakeholders and clients.
