IT Operations & Application Support professional based in Vigo, Spain, focused on evidence-based troubleshooting, Microsoft 365 and Entra ID support, endpoint issues, DNS and infrastructure diagnostics, documentation, escalation, and practical automation.
I use GitHub as a proof layer: small local-first tools, support labs, evidence workflows, and documentation that show how I investigate issues, structure findings, and create clearer handovers.
- IT Operations and Application Support
- Microsoft 365, Entra ID, identity, access, and authentication troubleshooting
- Windows endpoint support and evidence collection
- DNS, connectivity, service checks, VMware/vSphere exposure, and backup-awareness scenarios
- SQL-dependent application support from the support/escalation side
- Incident handling, escalation notes, runbooks, and knowledge base writing
- PowerShell, Python, React, TypeScript, and FastAPI used in practical support-focused tools
Local-first job opportunity tracker and review workflow built with React, TypeScript, FastAPI, and Python.
JOLT imports captured or pasted job text, parses opportunities, applies configurable fit rules, explains recommendations, preserves a resumable Batch Review queue, supports profile reclassification, exports evidence, and tracks reviewed jobs locally through Batch Review and Job Tracker workflows.
It is not positioned as a scraper, AI recruiter, or auto-apply bot. Its portfolio value is in the parser, rule profiles, explainable decisions, privacy-aware local workflow, persistent review queue, export package, tracker, and safe automation boundaries.
Local-first IT Operations diagnostic toolkit for turning Microsoft 365, Entra ID, endpoint, DNS, mail flow, and infrastructure evidence into support-ready troubleshooting reports.
Current status: sample-mode MVP. It demonstrates the diagnostic workflow, analyzer rules, local history, JSON/HTML reports, and frontend/backend architecture. Real Microsoft Graph collection is planned as a future read-only operational step.
PowerShell-based DNS auditing tool with a WPF GUI, CSV reporting, finding classification, and operational notes for support teams.
It focuses on practical DNS issues that often appear as unrelated support symptoms: authentication failures, intermittent application errors, Outlook/Teams connection issues, slow access, or inconsistent name resolution.
PowerShell WinForms utility for repeatable endpoint support checks, including TPM, Secure Boot, BitLocker, BIOS information, local intervention notes, and exportable evidence.
Canonical support/interview lab for incident handling, identity and access troubleshooting, API error interpretation, basic pipeline failure triage, documentation, escalation practice, and practical lab scenarios.
The previous VirtualBox foundation material has been consolidated into this repository under lab-foundation/virtualbox/, so the lab now has one main home instead of multiple small lab repos.

This GitHub is not meant to present me as a senior cloud architect, senior DevOps engineer, MLOps engineer, offensive security specialist, DBA, or software agency.
It is meant to show how I approach IT Operations and support problems:
- understand user impact
- collect useful evidence
- separate symptoms from likely causes
- document clearly
- automate repeatable checks where practical
- create support-ready outputs and handovers
- build safe local tools around real operational workflows
