I'm seeking fully remote, location-independent senior technical roles where I can modernize complex enterprise infrastructure, identity, Microsoft cloud and security environments. I prefer hands-on individual contributor positions with defined working hours and no regular on-call responsibilities. Available for occasional business travel.

@fabioalfonso
I modernize complex enterprise infrastructure across identity, Microsoft cloud, security and resilience, with 20+ years of hands-on experience.
What I'm looking for
I'm modernizing infrastructure, identity, security, and resilience for Talleres ZITRON, an international industrial organization with around 500 users and locations worldwide. I define its hybrid modernization roadmap and remain hands-on across architecture, troubleshooting, migrations, and implementation.
Previously, I strengthened privileged-identity controls and access governance for SIA - Inditex, integrating identity data into Azure Databricks and Power BI. At Izertis - ArcelorMittal, I designed Active Directory tiering and helped consolidate national environments into a standardized European domain across Spain, Germany, France, and Italy.
For more than 20 years, I've worked best in legacy, fragmented, business-critical environments where understanding dependencies, operational risk, and root causes matters. I use automation and AI-assisted tools to work faster, while validating assumptions and delivering production changes safely.
