01 About
I turn operational complexity into systems teams can trust.
For more than a decade, I’ve worked where infrastructure, software, and people meet. My job is to make that intersection less fragile.
That means seeing the whole system, automating the repeatable parts, and helping teams make clear decisions when the unexpected happens. I’ve led incident response across departments, supported follow-the-sun operations, and documented complex architectures so knowledge moves with the team.
