Work Experience
Senior Site Reliability Engineer and Senior DevOps Engineer
Self-employed
- Tasked for many years with keeping a multi-million dollar SaaS product online. This was first via bare metal servers, and in recent years via AWS and GCP. Finally, supporting and migrating these applications in the current era to Kubernetes.
- Implemented change management procedures, alerting tiers, incident management, and synthetic external tests to ensure the SaaS product remains online and operating within specifications.
- Supported engineering efforts to break down monolithic repos/services into microservices.
- Designed corporate and data center network footprints from architecture to implementation, support, and monitoring.
Network Architect
Self-employed
- Designed and implemented large scale networks for both corporate and data center. Shared my knowledge on IPv4, and IPv6 and connecting large cloud providers directly to the data center for migratory or scaling purposes.
- Managed scaling, procurement, and vendor relationships for networking equipment.
- Worked with security teams to define network perimeter (firewall and intrusion detection) threat and security models.
- Worked with major vendors (Fortinet, Cisco Ubiquiti, and Palo Alto Networks) with both their hardware offerings and some via the cloud (Prisma at Palo Alto and Meraki). Shared my knowledge on hardware appliance offerings, cloud, and open source implementations.
Network Engineer
EyeCheq Inc.
- Deployed a VPN system utilizing Tailscale to link field servers to the AWS VPC.
- Worked with telecom providers (AT&T and Verizon) to establish a cellular private network (think MPLS but via cellular), linking the routers deployed in the field directly to AWS (and getting their internet access from there).
- Deployed Cisco CSR routers in AWS to create a custom SD-WAN to satisfy the requirements of the client's technology.
Cisco Network Engineer
INTEGRITECH, LLC
- Worked with telecommunications vendors to establish an eVPN (MPLS) cloud between three distinct geographic locations.
- Connected a vendor-partner's network to the network of one of America's largest retailers.
- Deployed Cisco routers, cross-connects, and a network topology with the help of data center technicians, point-of-sale experts, and network engineers.
DevOps and Security Engineer
Anthem [Now Elevance] - AI
- Worked on service mesh and workload attestation mechanisms for various upcoming Anthem/Elevance initiatives. Co-developed a developer setup where the zero trust environment could be deployed in the development environment (and locally).
- Helped develop the service platform for the division by deploying AWS resources with Terraform and configuring Kubernetes and resources with Helm.
- Assisted developers in getting helm charts written for their applications and onboarded them into the CI/CD environment. Deployed and made them SPIRE/Zero trust configured.
