Ioannis Tsiftzis is a Principal Software Engineer based in Athens with over 18 years of deep Java SE/EE and framework experience and 11 years in progressive engineering roles. He has architected and delivered production systems across demanding domains—currency trading, online lottery, telecom charging, mobile marketing, banking and CMS platforms—bringing strong hands-on expertise in Spring, cloud-native tooling (AWS/GKE, EKS), Kubernetes, Docker, Terraform and GraalVM. At Agile Actors he moved from senior to principal responsibilities, blending backend architecture, CMS (Hippo/AEM/OSGi) and cloud infrastructure practices to modernize legacy stacks and accelerate delivery. Known as a “tennis addict” off-duty, he combines disciplined, performance-oriented problem solving with practical full-stack fluency, often surfacing operational improvements in observability and CI/CD that aren’t obvious from code alone.
