I am a high-level Infrastructure Architect and Systems Administrator with over 20 years of experience building and securing national-scale IT ecosystems. While I have served in executive roles—including Assistant National Statistician (CIO level) and Division Chief—my core passion and technical foundation lie in FreeBSD and Linux System Administration.
I specialize in deploying and managing robust, open-source-driven environments. My technical "DNA" is rooted in the stability of BSD and the flexibility of Linux, having spent years training government agencies on Asterisk, VoIP, and Open-Source adoption. I don't just manage teams; I architect the systems they build, ensuring they are scalable, secure, and cost-efficient.
Key Technical Strengths
Core Systems: Advanced FreeBSD/Linux Administration, Kernel-level understanding, and shell scripting.
Infrastructure & Cloud: Architecting High-Performance Computing (HPC) clusters (CoARE project) and on-premise cloud platforms using oVirt.
Network Security: Deep experience in pfsense (FreeBSD-based), Intrusion Detection Systems (IDS), VLANs, 802.1x, and PKI implementation.
IT Governance: ISO 9001:2015 Quality Management Representative and Data Protection Officer.
Highlighted Technical Projects
The CoARE Project (Project Leader): I led the deployment of the Philippines' first high-performance computing facility for research, supporting climate change simulations and genome mapping.
National ID (PhilSys) Cybersecurity: Spearheaded the cybersecurity architecture and policy for the National ID system, achieving over PHP 300M in cost savings through optimized integration strategies.
iGovPhils Data Center Operations: Managed the deployment of government-wide cloud services and the development of specialized apps like the Data Deduping App pilot-tested for the PSA.
Enterprise ERP Development: Directed the creation of an in-house ERP system currently utilized by multiple government agencies.
Why Hire Me?
I bring the rare combination of "in-the-trenches" technical mastery and high-level strategic oversight. Whether you need a hardened FreeBSD-based security gateway or a complex Linux-based HPC cluster, I provide solutions that are compliant with international standards (ISO 9001) and optimized for extreme scale.
