At BlackNode Systems, I architect and deploy production-grade Linux server environments, configuring storage and automated backups to support data integrity and fault tolerance.
I secure business networks with tools and practices including WireGuard VPNs, Firewalld/iptables, and SELinux. I also deploy and migrate mail, file-sharing, database, and web-hosting systems, and test disaster recovery by rebuilding systems and restoring data.
I conduct IT audits and infrastructure assessments to design cost-effective on-premise solutions and cloud-exit migrations. I also train business staff and provide diagnostics, data recovery assistance, and emergency technical support.
