Over the past 8 years, I've built and maintained networks and IT infrastructure for healthcare practices, law firms, government contractors, non-profits, media agencies, IT service providers, and hundreds of other businesses across the country. My consulting practice is professionally insured up to $2 million and I can provide a certificate of insurance upon request.

My professional experience includes (but is not limited to):
- Planning/managing/troubleshooting office networks, multi-tenant/commercial property networks, satellite campus properties, secure access networks, and even carrier networks.
- Administrating and implementing corporate IT security to align with strict data security standards (e.g., HIPAA, ISO 27001, and SOC2)
- Design, configuration, and supervision of tailored corporate networks, VPNs, access controls, firewalls, servers, and hybrid cloud connects. I am familiar with most of the major manufacturers of networking equipment.
- Implementing purpose-built cloud architectures for a variety of enterprise use cases on AWS and Azure (I can also set up Site-to-Site tunneling to/from networks based on AWS, Azure, and on-premises)
Please note that I am currently only accepting US-based clients and that my availability hours are based in Pacific Time.
I do not currently accept fixed price jobs or consumers (I am strictly a B2B consultant)

I earned my Cisco Certified Network Associate (CCNA) certification by completing extensive hands-on study and practice in networking fundamentals, routing and switching, IP addressing and subnetting, VLANs, trunking, Spanning Tree Protocol, EtherChannel, OSPF, NAT, DHCP, ACLs, IPv4 and IPv6, wireless networking, network security, and network automation. I used Cisco-focused labs, practice exams, and troubleshooting exercises to build practical skills in configuring, analyzing, and troubleshooting network environments. Through this preparation, I developed a strong understanding of how enterprise networks operate and how to identify and resolve common connectivity and configuration issues.
