About
Micah Domingue builds resilient enterprise systems with hands-on ownership.
Responsible for day-to-day operational stability across networking, Microsoft 365, Azure, and Active Directory, with real accountability during live incidents and service-impacting events.
Work is structured around clear escalation paths, validated fixes, and disciplined system hygiene so enterprise services stay available under pressure.

Networking & Infrastructure
Enterprise capability, engineered for real-world uptime
Focused on the layers that keep critical systems stable—identity, connectivity, cloud services, and the operational guardrails that keep them reliable under pressure.
Electric-blue visibility across infrastructure domains
Microsoft 365 tenant operations
Identity controls, access policies, and service health tuned for consistent availability.
Azure infrastructure
Cloud environments built with disciplined access, resilient networking, and service continuity.
Active Directory core
Directory structure, policy enforcement, and lifecycle controls that anchor authentication.
Operational stability
Incident-ready architecture, connectivity assurance, and SLA-aligned service continuity.
Experience / Responsibility
Operational ownership with enterprise-grade scope
Senior coverage and infrastructure practice grounded in real systems, real incidents, and measured accountability across cloud, identity, and networking.
Senior Weekend Technical Resource
Weekend command authority for critical infrastructure
Owns weekend operations for Microsoft 365, Azure, networking, and Active Directory—driving incident response, triage, and stabilization with clear technical accountability.
- Directs escalation and diagnosis across cloud, identity, and network domains
- Orchestrates response flow, communications, and real-time decision paths
- Validates mitigation outcomes and prepares precise weekday handoff notes
- Protects SLA performance by prioritizing high-impact stability risks
Home Lab — Network & Cloud Infrastructure
Serious infrastructure validation outside production
Jun 2022 – Present
Maintains a production-like lab to test network segmentation, identity workflows, and cloud operations with the same rigor applied to enterprise environments.
- Engineers segmented networks for isolation, routing control, and service boundaries
- Runs Microsoft 365 tenant administration for identity and access lifecycle
- Builds Azure infrastructure for compute, storage, and connectivity testing
- Secures remote access through VPN, SSH, and controlled tooling paths
- Applies patching, backups, and monitoring aligned with enterprise standards
- Automates repeatable operations to improve reliability and speed
Selected Work
Case StudyWeekend Queue Optimization Initiative
A real operational improvement effort that tightened weekend incident handling through precise prioritization, clear escalation lanes, and higher‑fidelity visibility across the support queue.
Reordered intake flow so Sev 1–2 incidents surface first, with lower‑severity work staged for controlled throughput.
Defined explicit escalation lanes to remove ambiguity during live incidents and reduce time‑to‑engage.
Raised incident visibility with structured checkpoints so critical tickets could not slip past triage.
Balanced workload flow by standardizing routing rules and aligning ownership across the shift.
Automated status signals and handoff notes to reduce manual overhead while preserving context.
