• Hands-on experience with message queuing systems such as AWS SQS/SNS and GCP Pub/Sub.
• Skilled in working with databases, including SQL (Oracle, PostgreSQL) and NoSQL solutions.
• Experience building and maintaining CI/CD pipelines using tools like GitLab, Jenkins, and bash scripting.
• Proficient with common development tools — Git, Maven, and IntelliJ IDEA.
• Practical knowledge of cloud platforms (AWS, GCP), Kubernetes, and serverless architectures.
• Strong experience with Infrastructure as Code tools such as Terraform, AWS CDK, Pulumi, Ansible, and Helm.
• Comfortable working in Agile environments with a DevOps mindset.
• Excellent communication and collaboration skills, with fluency in English.
