– I design and automate Oracle database platforms for complex, critical environments where manual operations don't scale and reliability is non-negotiable. – My work focuses on turning Oracle infrastructures into reproducible, observable platforms through Infrastructure as Code and automation-first practices. – Designing Oracle platforms as code using Puppet, Terraform and Git-based workflows – Building CI/CD pipelines for database provisioning, configuration and lifecycle operations – Implementing end-to-end observability with Prometheus, Grafana and alerting systems – Reducing operational risk and human error through automation and standardization – Supporting high-pressure environments where systems are already complex and expectations are high

– Worked with large enterprise environments in payments and aviation sectors, designing and automating Oracle database platforms in critical, highly regulated contexts. – Automating Oracle infrastructures using Infrastructure as Code and CI/CD workflows – Standardizing database provisioning and operations across heterogeneous environments – Improving observability, reliability and operational consistency – Supporting complex systems where downtime and manual errors were not acceptable

– At Actito, I worked on automating infrastructure and application platforms using Infrastructure as Code principles, with Puppet as a central component of the automation strategy in a hybrid environment. – Automating on-premise VMware and AWS infrastructure using Terraform as the control layer – Enforcing system state and configuration across platforms using Puppet

– At VoxelGroup, I worked on a large-scale, product-based platform delivered entirely as a service, operating as a high-throughput invoicing gateway for the hospitality sector, processing hundreds of thousands to millions of invoices per month with Oracle databases at its core. – Designing and automating an internal Oracle Database as a Service platform for standardized provisioning and lifecycle management – Automating database platforms using Rundeck, SaltStack, Bash and Jenkins pipelines – Operating Oracle and PostgreSQL platforms, addressing the significantly higher complexity of Oracle automation – Participating in the infrastructure evolution from on-prem clusters (Red Hat, GFS, KVM) to a Nutanix-based platform – Introducing Ceph to offload non-relational workloads from Oracle, improving efficiency and cost control

– Working at Atlas IT (later part of NTT Europe) on enterprise customer platforms, managing systems end to end: operating systems, storage, databases and application stacks – Developing a strong operational mindset focused on reliability, performance and troubleshooting under real production pressure – Administering a high-performance computing cluster at the Barcelona Supercomputing Center (CNAG), operating hundreds of compute nodes and large-scale parallel storage – Gaining deep expertise in Linux internals, system performance and automation at scale
