Kubernetes & Cloud Platforms
Extensive experience with Kubernetes on AWS EKS, GKE, OpenShift and IBM Cloud, including Istio/Envoy service mesh, Longhorn persistent storage, CSI/PV/PVC management, KubeVirt-based infrastructure and Argo CD GitOps deployments across large-scale production environments.
Observability & Monitoring
Deep expertise in building and operating observability stacks using Prometheus, Thanos, Grafana, Dynatrace Configuration-as-Code, OpenTelemetry, InfluxDB, Graylog/ELK and Langfuse, including SLI/SLO definition, synthetic monitoring and telemetry pipelines.
Automation & Infrastructure as Code
Strong background in automating infrastructure operations with Ansible (AWX, Rundeck), Terraform, Helm, Python, FastAPI, Bash, GitHub Actions and Jenkins, enabling large-scale bare-metal cluster management, CI/CD standardization and significant reduction of operational toil.
Linux Systems Administration
Production-level Linux administration including LVM management, MARS asynchronous block replication, OS patching, failover operations and L3 incident support across environments with 100k+ nodes.
Cloud Cost Optimization & Architecture
Experience leading GCP cost optimization initiatives including rightsizing, scaling, query and storage improvements, as well as developing reusable Terraform modules for AWS, GCP and Azure environments.
Data & Messaging Systems
Hands-on experience with Kafka, MongoDB, Aurora PostgreSQL, PostgreSQL, Redis and RabbitMQ for data transport, aggregation and storage in distributed production systems.
AI Engineering
Practical knowledge of AI engineering tools and frameworks including LangGraph, Pydantic, AWS Bedrock, Claude Code/MCP and multi-agent system design.
Incident Management & SRE Practices
Leadership of P0/P1 incident response processes within ServiceNow-based workflows, including RCA creation, runbook development and systemic reliability improvements across multi-team environments.

Project history
Engineering reliability for approximately 40 production services across six application teams in the FirmenOnline B2B life-insurance domain on AWS EKS with Istio/Envoy. Leading P0/P1 incident response, defining SLIs/SLOs, evolving observability with Dynatrace Configuration-as-Code, and developing reusable Helm libraries and CI/CD pipelines with GitHub Actions and Jenkins.
Administered production Kubernetes platforms on IBM Cloud and OpenShift with Istio service mesh and Argo CD GitOps. Built a monthly QoS screening pipeline over Prometheus/Thanos metrics and led GCP cost optimization for CaixaBank, developing reusable Terraform modules including Azure-provider exposure.
Owned production Longhorn on Kubernetes and operated Linux LVM with MARS asynchronous block replication. Automated bare-metal cluster operations at scale with Ansible via AWX and Rundeck. Provided L3 support, managed Kubernetes clusters with Istio and KubeVirt, co-engineered an enterprise monitoring suite (Python, FastAPI, Redis, InfluxDB) and managed a self-hosted Graylog/ELK stack.
