What I'm looking for

I am seeking a senior role focused on Linux and cloud operations where I can lead infrastructure projects, improve security and automation, mentor teams, and drive reliable, documented systems in a collaborative environment.

I am a Linux Systems Administrator with eight years of experience building, configuring, monitoring, upgrading and maintaining systems. I have managed and configured 200+ Linux servers, maintained VMware/ESXi and KVM virtualization, supported AWS high-availability infrastructure (EC2, RDS, ALB, S3, Lambda, VPC, CloudFront, Security Groups, IAM, ECS), led infrastructure projects, and successfully installed Appian on RHEL servers.

I document SOPs and system infrastructure, drive performance improvements (reduced resolution time by 80%), and implement security countermeasures to improve compliance. I hold a Bachelor of Science and two AWS certifications (2023), and I am eager to take on new challenges that expand automation, security, and cloud operations.
