PortugalWhat I'm looking for
I am a senior Linux system administrator and infrastructure engineer with over 25 years in IT, experienced in systems administration, database management (Oracle, PostgreSQL, MS SQL) and HPC cluster support. I combine hands‑on technical delivery with project leadership and technical planning to meet deadlines and business goals.
I have implemented automation and IaC solutions using Ansible, HashiCorp Packer, Shell scripting and GitLab, and worked with containerized deployments, Kubernetes, Docker and OpenMPI for HPC workloads. My background includes Oracle database administration (Dataguard, RMAN, GoldenGate, RAC), performance tuning and backup/recovery strategies.
I bring strong communication and stakeholder management skills from customer-facing and leadership roles, resilience under pressure, and a results-focused mindset for delivering complex migrations, disaster recovery testing and production support while collaborating with architects, project managers and vendors.
