About

I'm a Healthcare Technology Architect, Security Researcher, and Telecom Engineer with an electrical engineering background. I build EMR software, secure VoIP/telecom networks, and embedded systems.

As CTO at Povacare, I architect Electronic Medical Records software for modern healthcare. I also design antenna systems (Yagi-Uda), work with OpenWRT for router firmware, and build Raspberry Pi solutions for IoT and security applications.

I specialize in HIPAA, CMMC, NIST, SOC 2, ISO 27001, and PCI DSS compliance — building systems that pass audits stress-free.
