Many organizations still depend on aging infrastructure that continues to run critical workloads long after vendor support has disappeared. Many organizations discover these systems only when the one person who understood them is no longer available. I provide consulting to help stabilize legacy systems, plan migrations, and modernize infrastructure safely.

These systems may include legacy UNIX platforms, early PC-based systems, proprietary industrial hardware, or specialized environments that few engineers today have experience working with.

With more than 30 years of hands-on systems engineering experience, I provide consulting services to help organizations stabilize, troubleshoot, and modernize legacy computing environments.
