// My name is Corey Geiser [CV]

After 18 years in the AV industry working across commercial, residential, and high-security government environments, I learned that nothing is more frustrating than when the tools we rely on don’t work as planned. That’s why it is always good to have someone who knows how to make it right and do it without adding to the chaos.

For nearly two decades, I designed, documented, and remotely troubleshot the interfaces people counted on to control mission-critical systems.

Along the way, I:

• Cut end-user support ticket volume by 28% and task completion time by 40% by applying human-factors principles to interface redesigns.
• Reduced new system deployment time by 50% across 20+ product interfaces by standardizing technical documentation and SOPs.
• Supported 500+ enterprise and government client environments, remotely diagnosing hardware, software, and network issues under real operational pressure.
• Led cross-functional teams, coordinating engineering, IT, sales, and executive stakeholders to deliver systems for Fortune 500 clients and government agencies under strict compliance requirements.

Now I am building toward IT and cybersecurity — completing CompTIA A+, Network+, Security+, and CCNA certifications, working through TryHackMe labs while leveling up with Wireshark, Nmap, Active Directory, Cisco Packet Tracer, and Hyper-V virtual machines across Windows, macOS, and Android, plus PowerShell and Python scripting.

What I bring that most entry-level candidates can’t: real experience under pressure with mission-critical systems, a documentation-first discipline, and 18 years translating complex technical problems into plain language across diverse teams.
