Work Experience

Senior Site Reliability Engineer and Senior DevOps Engineer

  • 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.

  • 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.

Data Center to The Cloud

Led (as the technical lead) a team of SREs responsible for the maintenance of the hardware to support and the release of the company's SaaS product. Established direct connectivity to the cloud provider via Terraform/network infrastructure as code. Established all of the resources needed from the cloud provider via Terraform. Worked with engineering to set up a Spinnaker pipeline to deploy the code via Kubernetes pods which replaced our home-brew Bash script we used for years on bare metal.
