Dynamic SaaS Stateful Egress Firewall (2020)
Lead the architecture, development implementation, and deployment of a dynamic stateful egress firewall on a multi-provider SaaS platform. Impact assessment and tooling to automate large-scale tests was created using Terraform and Go, and the firewall management processes were implemented in Scala.
Scala - Golang - Docker - IPTables
On-Premises Kubernetes Deployment (2018)
Created Ansible playbooks and go tooling to manage on-premises Kubernetes clusters. Clusters are deployed with full encryption and authentication--TLS server identification, TLS client authentication, and Kubernetes RBAC permissions. Minimal configuration is needed to alter an existing cluster or add another to any environment. Haproxy Kubefigurator tool is used to configure load balancers to expose services outside the cluster.
Ansible - Golang - Bare Metal
Guetzli Image Optimization (2017)
Designed a distributed system to bulk-process over nine million images on our web properties. Utilized Google Container Engine to distribute processing across 3,600 containers across three regions, and maintained an average of over 99% CPU utilization, allowing it to complete nearly two years’ processor time in under 3 days. Wrote a high-performance queueing system, download queue, worker processes, and downloaders and distributed via containers both on-premise and in cloud infrastructure. This reduced our image sizes by about 80% on average.
Golang - Kubernetes - Google Cloud
Docker Development Environment (2016)
Designed and developed a local, synchronous orchestration system for containers allowing developers to quickly build and scale local development environments. It provides faster, more consistent deployments, lower resource overhead, and greater consistency between developers than previously used solutions. It was designed with scalability in mind and is easy to extend to handle additional projects and increases in project scope. Its artifacts are human readable and can be modified by the developers to fit their needs.
Golang - Docker
Container Factory (2016)
Developed a tool to hierarchically build Docker images. It allows for the use of inheritance, reduces code duplication, and maps build dependencies while providing a consistent build experience for all users.
Golang - Docker
SQL Server High-Availability Cluster (2012)
Utilized SQL Server 2012 RC releases to test and configure a Failover Cluster supporting AlwaysOn technology, which was put into production at General Availability release. It solved read / write contention issues by splitting workloads based on intent and purpose, significantly increasing performance.
