Campus Network Modernization

INFRASTRUCTURE 2021 · Network Engineer

Network Engineering · Security

Overview

Redesigned network segmentation, redundancy and infrastructure monitoring across a university campus — stabilizing services that support tens of thousands of students and staff.

The Challenge

Improve reliability and security across a growing campus environment with legacy infrastructure.

Constraints

Legacy infrastructureThousands of usersLimited maintenance windowsExamination periodsMultiple buildings / campusesBudget limitations

My Role

Network Engineer — I owned the technical delivery, architecture decisions, implementation phases and operational handover for this engagement.

Measurable Outcome

99.9%+ network availability across campus infrastructure serving 40,000+ users.

E WHAT I LEARNED

Reliability is engineered, not tested into place — the real wins come from sizing for peak demand, segmenting so failures stay local, documenting ruthlessly, and treating operations as part of the deliverable, not an afterthought.
