Hi, I bring over 13 years of experience in the IT industry, having worked with both local and international organizations. My expertise includes hardware and software support, networking, and system administration across Linux and Windows environments.
Currently, I serve as a Server and Applications Engineer at L3Harris-Aspire, supporting the Armed Forces of the Philippines (AFP). In this role, I provide technical support for C4ISTAR AFP site networks, including field support in Palawan, Cebu, and Zamboanga. I also manage and support built-in servers and software applications on AFP MCC trucks. My responsibilities include administration of AlienVault (SIEM) and Rapid7, Skype for Business servers (including certificate renewals and Polycom integration), Hyper-V environments and virtual machines, Active Directory, Microsoft 365, SharePoint, Exchange, SCOM, SCCM, Veeam, and MS SQL clustered high-availability databases.
Previously, I worked as a System Administrator II at the Development Academy of the Philippines. In this role, I handled installation and configuration of BIND9 DNS, management of Moodle LMS and CKAN servers, and administration of Lenovo ThinkAgile VX3320 hyperconverged infrastructure on VMware (including vCenter, ESXi, VSAN, and XClarity). I also supported platforms such as Power BI, Tableau Server, Microsoft SharePoint, Office 365, and WordPress, along with SSL (Certbot) renewals and GitHub.
Before that, I served as a Security Analyst under the Morgan Stanley–Accenture project for 2.5 years, specializing in Identity and Access Management (IAM) and Security controls. I provided access support to thousands of users via phone, email, and ticketing systems, utilizing tools such as Active Directory, Linux terminals, Symantec, and ServiceNow.
In addition, I have hands-on experience with technologies including Synology NAS, PHP, HTML, CSS, PostgreSQL, MySQL, Nagios, Ubuntu, Debian, Red Hat, Kali Linux, Burp Suite, SonicWall, pfSense, Google Cloud Platform, Apache, and Nginx.
I would welcome the opportunity to discuss how my skills and experience can contribute to your organization. Please feel free to contact me at your convenience.
Thank you for your time and consideration.
Yours sincerely,
Aaron Nuico Collo
