As a Senior System Administrator at Lexitas Legal, you manage a large infrastructure consisting of 100 Dell physical servers, 300 virtual machines, 80 Azure cloud servers, and 50 AWS cloud servers. Your responsibilities include Linux server patching, updating firmware for Dell equipment, and patching ESXi servers.

Your role also involves deploying and setting up remote servers across the United States to support the company's remote offices.

I manage and optimize cloud environments for our clients, particularly focusing on Azure services. I’ve worked on creating and maintaining Azure resources, such as VPNs, VMs, and user accounts in Azure Active Directory, along with implementing robust security measures like MFA, compliance reporting, and Just-in-Time Access. I also specialize in network security, provisioning server and network devices using Ansible, and managing ESXI hosts, VPN tunnels, and Fortigate firewalls for clients. In addition to this, I developed an application called Cyber-ECP, which allows users to securely connect to OT devices at remote locations across the United States. My role at Red Trident has allowed me to leverage my expertise in cloud infrastructure and network security to deliver secure, scalable solutions for our clients.

I was responsible for managing network monitoring tools, creating and maintaining alerts, and ensuring system availability. I upgraded and maintained SolarWinds NPM CMS and SAM servers, designed network maps with real-time dashboards, and created automated alerts to reduce downtime and support call-outs. I developed a Hurricane Response Plan for the NOC team and implemented SolarWinds outage maps for major incident response. As a member of the Change Advisory Board (CAB), I helped teams plan upgrades with minimal downtime. Additionally, I managed VPN connections on Palo Alto and Cisco ASA devices, troubleshot issues with Cisco ISE, and maintained network security. My role also involved automating alerts to restart services, facilitating major incident response calls, and collaborating with teams to ensure smooth system operation..

I automated system processes to reduce late-night call-outs and created server process watch daemons to detect and alert when a process was stuck. I managed Cisco network equipment, including firewalls and switches, and upgraded the network topology, increasing the backbone speed from 1GB to 10GB. My responsibilities included maintaining Windows Server backups, deploying patches, and managing Active Directory. I also handled Jira Server, including project management, workflows, and enterprise mail handling. Additionally, I monitored VMware ESXI backups using Veeam, deployed Docker containers to replace legacy systems, migrated physical servers to virtual machines, and established an IPsec VPN from Google Compute Engine to the main office using pfSense firewalls. I also collaborated with the development team on new software development for our core application.

My role involved managing Windows servers across two data centers, ensuring compliance through detailed reporting, and maintaining backup systems, including Symantec Backup Exec Server and tape libraries. I was responsible for deploying and maintaining VMware ESXI hosts, migrating critical servers from physical to virtual environments, and applying security patches to over 200 Windows servers. I also scheduled system reboots, deployed and maintained Symantec Endpoint Protection, and upgraded Solaris and Windows systems. Additionally, I played a key role in network security, monitoring VPN connections, deploying Checkpoint firewalls, and ensuring system-wide security compliance

In this role, I deployed and replaced over 5,000 machines across the organization, troubleshooting issues with Novell and leading the hardware deployment team. I also developed an application called Tech123, which helped with asset tracking, backup/restore of user data, and remote installation of applications. The application was built using MySQL, PHP, and Apache, and it streamlined many of the processes for IT management, making it easier to track assets and deploy software remotely.
