  • Foggy Cloud Architect

    2018 - 2019
    Cyvive
    • Managed microservice dependency so that any part of an organization dependency tree could be extracted and developed against in development (private or shared).
    • Implemented a just-enough-Linux (JeOS) approach for a host operating system via LinuxKit.
    • Isolated the Kubernetes and system workloads.
    • Removed TTY and SSH removed from modes as it was unnecessary in IaaC.
    • Used KataContainers for VM Isolation capabilities between containers.
    • Implemented multi-cluster and namespace networking isolation.
    • Migrated from transparent node to node encryption so that developers could safely use HTTP for microservices.
    • Enforced policy that without a mesh network, fallback to (legacy) ISTIO would be supported.
    • Implemented shadow traffic replication for production-like environments following the process from production to its resulting performance. This enabled defect detection prior to a true production release.
    • Provided on-demand AZ or instance-type upgrade options; companies also chose when to upgrade their cloud.
    • Handled the automatic healing and resizing of the control plane.
    • Performed ETCD persistence and recovery.
    • Constructed an infrastructure on demand for all environments (namespaces) as a per-hour-billing solution.

    • Replaced HashiCorp Vault with GitOps friendly secret encryption for public repositories via a provider key management system.
    • Handled a hybrid multi-cloud implementation of Kubernetes spanning multiple on-premises data centers and AWS regions. As disaster recovery and business continuity were a critical concern of Max Gaming, it was necessary to prove applications are capable of continued operation despite cloud provider or region failure.
    • Lessened in-cluster data redundancy with S3 incremental synchronization.
    • Implemented IaaC via Terraform controlled provision for AWS and GCP with all security hardening, networking, and network optimizations enabled.
    • Replaced Istio with Cilium, a more secure IPv6 compatible hybrid-cloud alternative.

Experience

  • Cyvive (Development)

    Cloud-Native Computing Foundation (CNCF) in advanced implementations (enterprise) assumes that companies have well-established CI approaches following GitOps while requiring IaaC, CD, microservice governance, and Kubernetes to operate as a data-center replacement.

    Cyvive enables microservice governance and CD to be implemented in any Kubernetes installation or to upgrade and optimize cloud providers to enable Kubernetes as a data-center replacement.

  • Sotekton: Agnostic Development (Development)
    https://github.com/sotekton/agnostic

    Cloud-Native Computing Foundation (CNCF) lays a path for the architecture provided and is supported by graduate projects such as Kubernetes.

    Developing software that conforms to these architecture best principles, and leverages the advantage of the entire supporting ecosystem is challenging using the usual development approaches, i.e., broadcast and multicast are unavailable.

    Agnostic outlines a raw minimal starting point following best practices to maintain backward compatibility with external and internal microservices while ensuring microservices behave like good citizens in CNCF environments.

  • Anonymous User Tracking Over Multiple Devices and Multichannel Attribution (Other amazing things)

    Anonymous users visit websites every day, yet companies are forced to present non-personalized content to them. I developed a machine learning approach to track and identify anonymous users against demographics identifying the same user (with a high degree of confidence) on multiple devices and from any of the attribution channels.

    The system was self-validating using the feedback of converted users to validate and correct the machine learning models daily.

  • Foggy Ubiquity's Language (Development)

    Microservice dependency, configuration, and secret management were nonexistent at the time; a few isolated approaches existed but nothing with permanence.

    Partnering with three universities and 35 industry publications, I created and open-sourced a universal microservice language using machine learning.

  • Containizen (Development)
    https://hub.docker.com/r/foggyubiquity/containizen

    These are maximum security minimal footprint base image/language containers.

    It has over 500,000 downloads from February to May 2020, Currently, it is the most secure, CI/CD compatible and update optimized base container available.

  • Automated Registration DDoS Protection (Other amazing things)

    This is a machine registration endpoint with no prior traffic should automatically register new machine users while being able to resist port scanning and DDoS attacks while maintaining cost by not triggering auto-scale events for false traffic.
