• Extensive hands‑on experience in the design, development, and management of Java applications
• Extensive hands‑on experience with Infrastructure as Code (IaC) tools such as AWS CloudFormation, Terraform, or CDK, with a proven track record of automating cloud infrastructure deployments.
• Advanced knowledge of containerisation technologies and orchestration platforms like Docker and Amazon EKS (Kubernetes) or ECS.
• Expertise in defining, implementing, and optimising CI / CD pipelines using tools such as AWS CodePipeline, Jenkins, GitLab, GitHub Actions, and others, applying best practices for pipeline efficiency and security.
• Strong background in networking, Linux or Windows administration, with the ability to architect secure, performant, and highly available cloud solutions.
• Proficiency with monitoring and log analytics tools such as AWS CloudWatch, ELK Stack, Prometheus, Datadog, or New Relic, to maintain observability and ensure operational excellence.
• Demonstrated leadership skills in managing complex, high‑pressure situations and guiding teams through incident resolution.
• Exceptional communication and presentation skills, with proven experience engaging with senior stakeholders.
