RIVERA

Summary

I lead large-scale IT operations and cybersecurity initiatives, most recently managing infrastructure for over 13,000 users across Europe with a team of 30 and $2.89M in network assets. I've driven measurable improvements in system uptime, ticket resolution, and cyber readiness—including leading a team that passed a regional cyber inspection on the first attempt. With a Top Secret/SCI clearance, CompTIA Security+ certification, and a degree in Cybersecurity Technology, I'm ready to bring operational excellence and technical leadership to mission-critical IT environments.
