    Principal Site Reliability Engineer

     —    2 years

    Remote Operations Engineer contract was requisitioned for various systems engineering duties and on-call emergency response, starting with developing infrastructure automation for the existing systems and deployment tooling in various stages of maintenance.

    The DoubleDutch systems have web-facing front-end CMS and API monolithic C#.NET components, large physical PostgreSQL databases, full text indexing, and queuing systems, as well as roughly one hundred other features/components running in containers, with white-labeled mobile applications for both Android and iOS.

    With baseline automation repaired or re-established, my team was allocated to an experimental platform restructuring project which was being built by a remote team in Amsterdam with Java and Docker (compose).

    While that project was ultimately canceled, we produced the systems automation for the virtualized infrastructure in Rackspace's OpenStack public cloud with Chef and Docker, and at the same time ported the Docker image builds to Google Cloud Build, and wrote Helm charts for every component to run in Kubernetes at availability and responsiveness levels measurably exceeding any previous capability, with significantly reduced human intervention. Much of this would be later re-usable.

    Later, a new Platform team was formed, absorbing the previous Engineering Operations, Integrations, and Data teams. Our function was to migrate the legacy infrastructure components while building any new components in our newly designed Google Cloud Platform / Google Kubernetes Engine infrastructure and tooling.

    • Design, deployment and maintenance of all existing physical and virtual Infrastructure with Chef.
    • Design of, and iterative migration towards Google Kubernetes/Compute based infrastructure in Iowa, Belgium and Frankfurt.
    • Designed and implemented redundant dedicated interconnect hybrid connectivity solution between Rackspace RackConnectGlobal Equinix and Google Compute Platform.
    • Designed and implemented redundant VPN/IPSec hybrid connectivity solution between Rackspace regional ServiceNets and Google Compute Platform.
    • Migrated in-house Identity authentication and authorization system and associated database clusters and workloads to Google Cloud Platform and Kubernetes.
    • Development of Helm charts repository for container (Docker) workloads.
    • Extensive usage of Google Cloud Build for all container workloads including continuous integration of pull requests from GitHub Enterprise with assets stored in the Google Container Registry for continuous vulnerability and exploit scanning.
    • Database administration of PostgreSQL clusters with pooling, replication management and backup/continuous archiving.
    • Maintenance/support of legacy software systems and application deployment tooling.
