Acerca de Tomas

I help organizations stabilize and deliver complex infrastructure and platform transformations in live production environments.

With 17+ years of experience across AT&T and team.blue, I specialize in programs where execution risk is high, dependencies are difficult to control, and timelines are already under pressure. My work combines realistic planning, milestone governance, dependency management, stakeholder alignment, and calm execution to turn complex transformations into structured, deliverable programs.

A major recent program involved migrating 138PB of data and relocating 1,455 physical servers across international environments while maintaining continuity for 32,250 live instances. The transformation also reduced power footprint by 40%, from 850kW to 500kW.

I am typically engaged when a business needs to recover a drifting program, structure a high-stakes migration, strengthen PMO governance, or bring executive clarity to complex infrastructure change.
