Introduction

David A. Mosele III (Davey) — Chicago, IL

Cybersecurity and Computer Information Technology student at Purdue University Northwest. I combine hands-on experience in networking, systems administration, and technical support with leadership in creative and technical settings. I thrive at the intersection of technology and teamwork, from managing Cisco switch deployments to running complex productions in theatre. I’m eager to keep building my technical skills while pursuing certifications like CompTIA Network+ and Security+.

Key strengths: Linux administration, Cisco network operations, homelab tinkering, POS & retail systems troubleshooting, technical theatre management, leadership, and adaptability.
