As a DevOps Engineer within the GraalVM release team at Oracle Labs, I lead efforts in maintaining and scaling cross-platform infrastructure across cloud (OCI) and on-premise systems. My responsibilities include orchestrating CI/CD pipelines, enhancing observability with Prometheus, Grafana, ELK, and packaging and releasing GraalVM builds across Linux, Windows, and macOS. My work directly strengthens the reliability, scalability, and speed of product delivery. – Spearheaded infrastructure management for GraalVM across OCI (linux and windows) and on prem (Mac machines), ensuring uptime and scalability. – Built and maintained monitoring using ELK, Prometheus, Grafana, and Loki. – Building and managing CI/CD Infra with GitLab (shell, docker and k8s executers), BuildBot, and OCI build service. – Leading packaging, release, and multi-platform delivery for GraalVM across Linux, Windows, and macOS systems. – Managing OCI native applications like GDS (GraalVM Download Service) and other internal applications ensuring the availibility and the reliabilty of these services (Terraform, Oracle Kubernetes Engine...) – Working in 24/7 uptime environments with on-call rotations Doing all this of course means a lot of troubelshooting, and I want to mention, toubelshooting is something that I master, I specialize in end-to-end troubleshooting across cloud and hybrid environments, confidently resolving infrastructure failures, deployment issues, security vulnerabilities, and application incidents.

– Migrating services to K8s clusters( Kubernetes, Docker, Helm, Terraform..) – Working with OCI Cloud environment by deploying and monitoring cloud-native applications – Optimize Oracle's Cloud Infra Configuration by Migrating existing k8s clusters from using AMD CPUs to having ARM CPUs and besides this, ensuring the availability of services that are currently on these clusters (zero downtime migration)
