Charles Landwehr

I am a versatile and results-driven Senior Systems Administrator with over 20 years of experience in system engineering, infrastructure automation, security, cloud migration, and incident management. My career has been marked by a commitment to delivering scalable solutions and modernizing IT environments in both enterprise and startup settings. I have a proven ability to lead cross-functional efforts that improve uptime, reduce costs, and streamline operations.

At ThreatQuotient, I successfully migrated an entire OpenStack-based development infrastructure to Virtuozzo, covering approximately 100 VMs. I also transitioned the on-prem Atlassian suite to Atlassian Cloud, integrating Okta SSO, and developed automated AWS snapshot cleanup scripts that significantly reduced storage costs. My expertise in deploying comprehensive Kubernetes monitoring solutions and managing AWS environments has enhanced operational visibility and efficiency across critical systems.

In my previous roles, I have demonstrated my ability to innovate and implement effective solutions, such as developing an Android app for data cleanup used by over 1,000 delivery vehicles and automating Linux patching via Ansible, which cut deployment time by over 60%. I am passionate about leveraging my extensive experience to contribute to dynamic teams and drive impactful IT initiatives.
