Enterprise Infrastructure Engineer · Remote Contractor · Infrastructure Consultant
Reliable infrastructure for enterprise systems that cannot simply stop working.
I help organizations operate, troubleshoot and modernize critical infrastructure: Linux, AIX, IBM Power Systems, high availability, middleware, automation, virtualization and legacy environments that still run important business workloads.
Based in Brazil, available for remote international contract work, consulting engagements and fixed-scope infrastructure projects.
What I help with
My work sits between traditional systems administration and modern infrastructure engineering. I am most useful in environments where reliability matters, the stack is not entirely new, and someone needs to understand the whole system instead of only one small layer.
Enterprise Linux & Unix
RHEL, Rocky Linux, Ubuntu, AIX and zLinux administration, troubleshooting, patching, migrations, hardening and production support.
IBM Power & legacy infrastructure
Experience around IBM Power Systems, AIX, enterprise Unix environments, legacy workloads and modernization projects that require caution and context.
High Availability & clustered systems
Pacemaker, Corosync, GPFS, clustered filesystems, failover design, service orchestration and operational recovery planning.
Automation & operational tooling
Ansible, shell scripting, infrastructure reports, repeatable procedures, upgrade workflows, runbooks and handover documentation.
Core expertise
Operating systems
Linux, RHEL, Rocky Linux, Ubuntu, AIX, zLinux, Unix troubleshooting, systemd, NetworkManager, SELinux and storage-aware administration.
Infrastructure platforms
IBM Power, VMware, KVM/libvirt, container hosts, enterprise storage, GPFS and infrastructure services running across hybrid environments.
Middleware-adjacent infrastructure
Production environments around IBM MQ, application platforms, database-adjacent Linux infrastructure and operational dependencies.
Modernization
Migrating old systems carefully, documenting risks, preserving business continuity and turning fragile environments into maintainable platforms.
Selected background
I have worked in enterprise infrastructure and production support roles for companies such as IBM, SAP, Dell, Atlassian, SmartBear and Veeam. My background combines hands-on systems work, customer-facing troubleshooting, automation, migrations and support for critical environments.
I am especially interested in work that involves real infrastructure problems: migrations, reliability, high availability, Linux/Unix operations, automation, legacy modernization and environments where documentation and operational clarity matter as much as technical execution.
Available for contract work
I am available for remote international contractor opportunities, consulting engagements, part-time infrastructure work and fixed-scope projects.
I am not seeking relocation or a country-specific full-time employment arrangement. The best fit is remote contract work where I can contribute senior infrastructure experience to a specific operational or modernization need.
