I formulated and executed comprehensive migration strategies for the shift from IPv4 to IPv6, accomplishing complete migration within 12 months while ensuring little disruption to business operations.
I developed an IPv6 adoption roadmap delineating essential milestones, timescales, and requisite resources, hence facilitating a systematic and effective transition process.
I put in place complex security protocols for IPv6 networks, including strict firewall controls through Palo Alto Networks. This reduced the chance of security holes and improved network safety.
I developed a multi-cloud strategy that effectively integrated AWS, Azure, and Google Cloud, improving the company's adaptability and mitigating vendor lock-in risks.

DKW Communications, Inc – NOAA Affiliate April 2021 – May 2023
Lead Telecommunications/Communications Integration Engineer/Architect
I implemented intrusion detection systems (IDS) specifically designed for IPv6 traffic, enhancing the overall security framework, and facilitating the early identification of potential threats.
I developed DDoS management methods for IPv6 networks, reducing impact and assuring business continuity during extensive attacks.
I engaged with interdisciplinary IT teams and departments, promoting a collaborative strategy that guaranteed the smooth integration and interoperability of IPv6 solutions throughout the enterprise.
I facilitated training sessions and workshops for IT personnel on IPv6 best practices and security protocols, assuring preparedness and proficiency in administering IPv6 networks.
I created and sustained extensive documentation for IPv6 implementation, transition, and security, establishing a significant repository of knowledge for future reference and problem resolution.
I supervised and enhanced network performance within an IPv6 framework, utilizing sophisticated analytics to guarantee the high availability and dependability of cloud services.
I directed a cross-functional team to architect and deploy a highly scalable cloud infrastructure for a worldwide organization, achieving a 35% decrease in operational expenses.
I formulated and implemented cloud security rules and best practices, resulting in a 40% reduction in security incidents and ensuring the robust protection of sensitive data.
I ensured that the network solution complies with federal, NOAA, and NWS requirements. In this case, baseline secure configuration, network security hardening, network security monitoring, network encryption, redundant connections, optimized network configuration, the right amount of network bandwidth, Managed Trusted Internet Protocol Service/Trusted Internet Connections, and adding cloud hosting providers to the network infrastructure as needed are some of the things that are covered.
I directly assisted the NWS EIS transition team in the creation of the NWS-specific EIS transition (expatiate).
I gave advice and, if needed, updated the NWS's EIS Transition plan. This could include, but is not limited to, redesigning the network to move from Lumen and Verizon WANs to a single AT&T WAN, managing network bandwidth and quality of service (QUs), keeping track of activities that involve shutting down systems, looking for ways to make the system more modern, and testing out new services and features.
I reviewed any proposed EIS service and system designs to ensure they are properly configured to the NWS’s technical and network security requirements.
I examined business procedures and offered suggestions for ensuring smooth integration among all NWS service providers.
I reviewed the NWS’s telecommunications infrastructure to obtain a deep understanding of the current functionality and their inventory.
I reviewed the portions of the National Oceanic and Atmospheric Administration (NOAA) EIS RFP and AT&T’s awarded proposal that apply to NWS’ services. If there were any concerns about the proposed transition period, I recorded them down. Some of these were areas that might have been missed between the RFP/RFQ and the quote, as well as any areas where proposed modernization (like switching from TDM to Ethernet circuits, SD-WAN, etc.) could happen faster with little impact on the approved agency transition plan.
I conducted system architecture and configuration reviews as the EIS contractor, tasked with providing new, changed, improved, or modernized versions of EIS services.
I designed, implemented, and optimized wireless networks using both Aruba and Cisco Wi-Fi solutions.
I collaborated with stakeholders to gather requirements and translate them into scalable and secure network designs.
I configured and optimized Aruba and Cisco wireless hardware, including access points (APs), controllers, and switches.
I ensured proper placement and configuration of devices for optimal network performance.
I implemented and managed security measures for wireless networks, leveraging Aruba ClearPass and Cisco Identity Services Engine (ISE).
I ensured compliance with security policies and standards through continuous monitoring and enforcement.
I implemented advanced security features such as WPA3, EAP-TLS, and multi-factor authentication.
I monitored and analyzed the performance of Aruba and Cisco wireless networks, identifying and addressing potential issues.
I implemented optimization strategies to enhance network efficiency, capacity, and user experience.
I examined and confirmed the current network architecture and configurations.
I designed and set up a new network solution that supports the NWS's long-distance calls, Wide Area Network (WAN), Local Area Network (LAN), and connections to NOAA and other business partners. The NWS WAN Customer Edge is primarily leveraging Cisco routers and equipment. The NWS WAN occasionally utilizes Juniper routers and firewalls.
I coordinated directly with the NWS team on the circuit priorities. NWS has several large, expensive circuits that they will look to transition first. Ensuring that a best-practice, repeatable design is implemented and that the changes limit or eliminate disruption will be extremely important to maintaining NWS services during this transition.
I led the installation of the IXRE router and cutover, SRS, E911, N2.5 CT, and call testing.
I ensured that the network solution satisfied the requirements of the Federal Government, NOAA, and the NWS. These included, and were not limited to, setting up the network securely from the start, making the network more secure, monitoring the network for security issues, encrypting the network, making sure there are backup connections, and improving performance. It is also important to make sure that the network bandwidth is the right size and that Managed Trusted Internet Protocol Service/Trusted Internet Connections are built in. The network infrastructure should also include cloud hosting providers.
I coordinate and ensure that OTA signals that are used to program, update, configure, and provision hardware devices are collectively OTAP (Over-The-Air Programming). One example is over-the-air activation (OTAA), which allows wireless activation to NOAA’s WFO Offices.
