Summary
🤩
Rockstar🎓
Top SchoolKyri Petrou is a Senior Software Engineer based in Melbourne with five years of industry experience building and optimising containerised applications, CI/CD and data pipelines, and IaC deployments. He brings deep hands-on expertise in Scala (JVM), Python, Docker, PostgreSQL and IaC tools like CloudFormation, CDK and Terraform, and translates business requirements into pragmatic technical solutions. Kyri has progressed from research engineering (PhD-level electrical engineering) into leadership roles, most recently serving as Lead Software Engineer at Dixa and now at Ziverge. He is an active open-source contributor to high-profile Scala projects such as ZIO and Caliban, where his work focused on performance optimisations and modernising codebases for Scala 3. That background combines rigorous academic training with production-facing performance tuning, making him comfortable both with low-level concurrency improvements and large-scale deployment automation. Colleagues describe him as someone who ships reliable systems while quietly improving core libraries for long-term maintainability.
