Sobre mí
I am a Senior Infrastructure Architect with over 40 years of experience rescuing critical business systems. I specialize in Windows Server recovery, legacy database extraction (Clipper, FoxPro, XBase), and resolving complex network infrastructure failures.
Vetted as an official technical instructor by Computer Associates, I solve the catastrophic backend problems that general IT support cannot handle.
If your server is down, your legacy data is corrupted, or your network is exposed, I deploy precise architectural solutions to rapidly restore your business continuity.
