DevOps Engineer · AZMA Espadana

• Built and ran a Kubernetes platform with 5 VM-based control-plane nodes and 20 bare-metal workers, plus 2 spare servers for capacity and recovery.
• Set up Ceph with RBD, CephFS and S3, giving stateful workloads block, shared-file and object storage on one platform.
• Used Kafka as the buffer and replay layer for a logging pipeline peaking at 10 TB+ per hour, absorbing spikes and ending the log loss of the previous setup.
• Tuned Elasticsearch with hot/cold tiers and ILM, and moved worker capacity from VMware vSphere to bare metal for better performance and stability.
