Available to hire
Hi, I’m Constantine A. Kyrou. I’m a results-driven federal AV/UC systems integrator and small business owner with 20+ years of experience designing, engineering, and managing mission-critical audiovisual and unified communications infrastructure for U.S. government agencies. I hold an active DoD Secret clearance and AWS Certified Solutions Architect (Professional), and I lead Constantine Craft Solutions, LLC / Nautilus AV as SAM.gov-registered prime contractors. I’m passionate about delivering robust, secure UC/AV solutions and mentoring teams to exceed client expectations.
In my work, I specialize in multi-vendor control systems (Crestron, Extron, QSC, Biamp, AMX), Cisco/Polycom/Microsoft Teams UC platforms, and cyber security hardening (DISA STIGs). I design with AutoCAD and Visio, manage change control, and develop clear SOPs and end-user training. I enjoy collaborating with customers to translate complex requirements into reliable, scalable deployments while fostering knowledge transfer to teammates and partners.
