Rafael Alba

IT Operations and Technical Support professional focused on Microsoft 365, Entra ID, Windows endpoints, DNS, support documentation and practical troubleshooting workflows.

I build small tools, lab scenarios and runbooks that make support work more repeatable: collect evidence, separate assumptions from facts, document the fix and reduce recurring incidents.

What I Work On

  • Microsoft 365, Entra ID and access troubleshooting
  • Windows endpoint checks, TPM, Secure Boot, BitLocker and baseline validation
  • DNS and infrastructure troubleshooting
  • Incident documentation, runbooks and knowledge base articles
  • Support automation with PowerShell and small Python utilities
  • AI platform support scenarios: API errors, access issues, basic pipeline triage and escalation notes

Featured Projects

Project Focus Why it matters
DNS Audit Tool PowerShell DNS auditing and CSV reporting Finds stale records, PTR issues and forward/reverse mismatches that can create confusing operational symptoms.
Endpoint Support Checklist PowerShell WinForms endpoint checks Standardizes device support checks for BIOS, TPM, Secure Boot, BitLocker and intervention history.
Enterprise Ops + AI Platform Support Lab Support-focused AI/platform operations lab Shows incident handling, API error interpretation, escalation and support documentation.
VirtualBox Homelab Foundation Practical IT homelab planning Documents a realistic foundation for identity, DNS, endpoint and support practice.
Rafael Alba Site Portfolio and lab notes Public site with practical troubleshooting articles and service positioning.

How I Approach Support Work

  1. Define the symptom clearly.
  2. Identify scope: one user, many users, one device, one network, one service or a wider incident.
  3. Collect evidence before changing configuration.
  4. Separate identity, endpoint, network, policy and application layers.
  5. Document the investigation path, not only the final fix.
  6. Turn repeat issues into checklists, runbooks or small tools.

Current Focus

  • Microsoft 365 and Entra ID support scenarios
  • Endpoint support tooling and baseline documentation
  • DNS troubleshooting and audit workflows
  • Homelab scenarios for practical infrastructure support
  • AI-assisted support workflows with clear guardrails
