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