Message

At Pecan Energies Ghana Limited, I administer RHEL-based HPC and GPU server nodes supporting geoscience, seismic-data processing, engineering analytics, and AI-assisted offshore energy workloads. I provision and validate compute nodes and monitor Kubernetes worker nodes and NVIDIA H100 GPU health.

I previously administered Linux systems at Aker Energy Ghana Limited, supporting production and other environments. I maintained RHEL servers, planned monthly patching through Red Hat Satellite, and developed Ansible playbooks and Bash scripts to automate routine administration.
