What I'm looking for

I seek a hands-on AV/technical operations role where I can lead installations, provide customer-facing support, and improve processes using Excel and 3D modeling within a collaborative, safety-focused organization that values growth.

I have seven years of hands-on experience in audio-video technology, combining field installations with office operations to deliver reliable, customer-focused AV solutions. I supervise installation crews, coordinate third-party subcontractors, and place and configure microphones, lighting, sound and rack systems to meet production specs.

I have installed and supported AV systems across military, hospital, government and educational sites, including video walls, networked display screens and overhead speakers. I have served as an IT Transport Specialist for a government office and contributed to projects at the Salisbury courthouse and Baltimore City Hall, ensuring systems integration and on-site technical support.

In office roles I leverage Microsoft Excel and 3D modeling to manage data, reconcile invoices, onboard customers and support sales representatives. I prioritize clear communication, proactive customer outreach and process improvements to maintain smooth operations and stress-free issue resolution.
