Infrastructure automation, security modernization, and technology leadership for mission-critical environments.
David C. Fields, M.S., combines enterprise infrastructure, networking, cybersecurity, automation, architecture, platform operations, consulting, managed services, and people leadership. His strongest fit is where regulated or operationally critical systems must become more secure, observable, repeatable, resilient, and supportable.
35+years across engineering, operations, consulting, and leadership
10+engineers and technicians recruited, developed, and led
$1M+managed-services and engineering practice directed
10,000+annual incidents and requests supported by enterprise automation
Best-fit opportunities
A focused intersection of engineering, security, operations, and leadership.
Platform, DevSecOps & Operations Leadership
Platform engineering lead, infrastructure manager, technology manager, director, architecture lead, and senior operations roles requiring both technical credibility and service-delivery judgment.
Public Sector, Critical Infrastructure & Consulting
Government, defense, utility, healthcare, financial-services, transportation, and consulting work involving modernization, resilience, cybersecurity, automation, continuity, and operational risk.
Primary market position
Senior Infrastructure Automation & Security Modernization Leader
This position concentrates David’s broad background into one practical value proposition: modernize complex infrastructure by connecting automation, cybersecurity, platform operations, resilience, documentation, service management, and leadership rather than treating them as separate disciplines.
Strongest evidence
What differentiates David.
Enterprise automation
Designed and supported Python, Ansible/AWX, Terraform, Git, Azure DevOps, ServiceNow, PagerDuty, Rundeck, API, Docker, and Kubernetes-related automation in a regulated 24x7 financial-services environment. Automation supported more than half of incoming ticket volume and 10,000+ incidents and service requests annually.

Longstanding work across enterprise routing, switching, firewalls, remote access, WAN, data-center platforms, load balancing, IAM-related controls, monitoring, incident response, vulnerability remediation, business continuity, and disaster recovery.
Leadership and service delivery
Directed a $1M+ managed-services and engineering practice, recruited and led more than 10 engineers and technicians, and established centralized monitoring, ticketing, escalation, documentation, support, and executive-reporting capabilities.
Current hands-on work
Actively developing Linux, container, Kubernetes/K3s, AI-agent, automation, GitHub Actions, software, and SaaS capabilities through Lighthouse Digital Logistix, CharterVantage, public repositories, and a clearly labeled technical-validation lab.
Business and operating perspective
Combines technical engineering with consulting, vendor management, procurement, documentation, process design, incident leadership, compliance, customer operations, and ownership of business-critical technology systems.
Work arrangements
Practical flexibility.
- Remote opportunities across the United States
- Appropriate hybrid roles in Central Ohio
- Selected onsite work when scope, compensation, and travel are reasonable
- Full-time W-2, contract, contract-to-hire, and consulting
Credentials
Education and certifications.
M.S., Information Security & Assurance — Norwich University
B.S., Computer Information Systems — DeVry University
Currently held: CompTIA Security+, ISC2 Certified in Cybersecurity (CC), and ITIL v3 Foundation.
Previously held / expired: VMware VCP5-DCV, CISSP, CISM, CISA, CCNP Enterprise, CCDP, CCSE, CCNA, and CCDA. Historical or expired credentials are not presented as current.
Experience classification matters. Enterprise production experience, consulting and operating-company work, product development, and lab or technical-validation work are identified separately rather than blended together.
