Background

About Oriol Centelles

I am an Infrastructure Architect and SRE Specialist, with a strong focus on designing and managing highly available, secure, and scalable infrastructures. With extensive experience across public and private cloud environments, I ensure the systems I oversee are resilient, efficient, and consistently optimized for high performance and reliability. My background covers a broad range of areas including cybersecurity, automation, and continuous development workflows, with emphasis on implementing high-availability architectures. I specialize in building infrastructure that supports CI/CD, proactive monitoring, and mission-critical operations aligned with business continuity and growth goals. Over the years, I’ve developed deep expertise in managed high-availability services, such as: • Clustered infrastructure with automatic failover • Distributed storage with strong fault tolerance • Hardened operating systems for critical environments • Fully automated CI/CD pipelines • 24/7 proactive monitoring with intelligent alerting • Disaster recovery with minimal RTO and RPO • Multi-layer redundant load balancers • Synchronously and asynchronously replicated distributed databases • Enterprise virtualization with live migration • Continuous incremental backups with deduplication • Multilayer security systems with integrated SIEM • Kubernetes container orchestration in mission-critical environments • Hybrid and multi-region cloud architectures with 99.99% SLA guarantees These are more than just technical capabilities—they represent a mindset of building solutions that are robust under pressure, scalable by design, and secure at their core. — Core Specialties • Public & Private Cloud Architecture • Cybersecurity & Data Protection • IT Process Automation & Optimization • CI/CD & Continuous Development Solutions • High Availability & Fault-Tolerant Systems • Network & Cloud Infrastructure Design • Cloud Integration & Migration Strategies • Virtualization (ESXi, KVM, Hyper-V, Azure) • Resilient Infrastructure Deployment • Strategic IT Planning & Execution — Key Technologies • Ceph • Docker Swarm / Kubernetes • Prometheus + Grafana • Ansible / Terraform / Jenkins • HAProxy / NGINX / Apache • Zabbix / Icinga / Elastic Stack / Librenms • GlusterFS / DRBD / RBD / Corosync / Pacemaker • Proxmox / oVirt / VMware vSphere / OpenStack • Veeam / Bacula / Restic / Velero • Keycloak / Vault / Bitwarden / Intune • PostgreSQL / MySQL Galera / MongoDB / Redis • Cloud Providers: AWS, Azure, GCP • SIEM: Wazuh / Graylog / Splunk • CI/CD: GitLab CI, Jenkins, ArgoCD, FluxCD
