Work Background
MastercardSenior Cloud Operations Engineer
Feb. 2025Prague, Czechia🔧 Senior Cloud Operations Engineer with a strong background in delivering and maintaining scalable, secure cloud infrastructure. I specialize in designing and implementing AWS-based solutions using Terraform, managed through GitLab CI/CD pipelines. 🚀 I work closely with internal teams and customers to provision and manage key infrastructure components including EC2, security groups, Route53 records, load balancers, KMS encryption, SSM parameters, and ECS clusters. 🔐 As part of my team’s responsibilities, we own the management of IAM permissions, ensuring secure and compliant access controls across environments. I also support configuration management using Puppet, along with Consul and Vault for service discovery and secrets management. 📈 I’m actively involved in monitoring and observability with SignalFx, and participate in a rotating on-call schedule to ensure infrastructure reliability and performance. 🐧 Comfortable in Linux system administration, I’m also experienced in managing S3 storage, troubleshooting infrastructure issues, and continuously improving DevOps practices.
