John Macdonald work experience
A career timeline built from the work history available for this profile.
Infrastructure Engineering Senior Advisor
After a successful tour at Cigna as a contractor providing senior network engineering services, I was converted to a full-time permanent employee. My department rebranded in June of 2023 to Evernorth Health Services. I became a project lead for our technology lifecycle refreshes/upgrades, have been a subject matter expert in LAN/WAN as it pertains to designing/supporting our remote sites through private MPLS and SD-WAN over the internet, company mergers and acquisitions and related network integrations, and connectivity with our many B2B partners worldwide. Recently I've overseen the network overhaul of some of Express Scripts' largest pharmacies to continue to insure network reliability and performance for those operations.
Senior Network Engineer
Talon placed me as a contractor at Cigna doing enterprise network engineering in a senior role. Projects included LAN/WAN integration and modernization of healthcare companies which Cigna had acquired over the last few years. Most of my tasks involved Cisco ISR/ASR routers, 37xx/38xx series access switches, 26xx series wireless access points running through a core wireless LAN controller cluster, as well as working with our primary telecom carriers for delivery, testing and turn-up of Ethernet, OC and MxT1 circuits, insuring redundancy where possible with multiple dynamic routing protocols. All projects were completed with great success.
Principal On-Site Support Engineer
I was hired on by Netscout Systems in the belief that my years of experience with network operations and engineering would help bridge the gap between that experience and a role as a hardware/software platform consultant for Netscout's NGeniusOne network monitoring suite. The position was mostly software application support as well as direct consulting with my assigned customer regarding their needs and possible solutions. In the end, the mating of my previous roles as an engineer into an application support role didn't pan out, and I resigned this position to pursue further challenges more suited to my education and experience.
Senior Network Engineer
I served as Senior Network Engineer, providing experience and professional level knowledge in Cisco networking devices and systems. In addition, my advanced knowledge in Checkpoint firewalls was key in their data center migrations, as well as supporting a customer in a unique environment built on Checkpoint. I also served as the network lead for the migration of that customer from their data center in Toronto into the Norcross facility.Daily responsibilities included operation, management and monitoring of all hosting network devices and systems, as well as senior-level network participation in customer projects and initiatives.
Senior Analyst, Enterprise Security Delivery
This position was to function as a security architect, providing design, testing, implementation and documentation through all stages of projects relating to improving the technology security measures for all systems used by Macy’s and Bloomingdales department stores and administrative offices. Specific examples included the segregation of servers processing PCI-sensitive data onto their own firewalled network segment, improving the Wireless LAN security to include WPA2 + 802.1X and PKI certificate for all authorized devices (laptops, tablets and mobile phones). I also held a critical role during the corporate Mobile.Me project, a BYOD mobile device security initiative.
Netscaler Escalation Engineer
