\item{Along with the engineering team, designed and implemented multiple cloud hosting products using the open-source platforms Foreman, OpenNebula, and Netbox.} \item{Designed and implemented, along with the engineering, development, and product teams, multiple cloud hosting products culminating in the Brokkr compute marketplace.}
\item{Worked with CPO to define roadmap and balance engineering and product goals and limitations.} \item{Worked with CPO to define roadmap and balance engineering with product goals and limits.}
\item{Built CI/CD systems for Brokkr, Vulcan, and Oblivion products using Gitlab, Ansible, Terraform, and Vault.} \item{Maintained devops monitoring for leadership and product team, to provide quality, real-time information about software releases in our UAT and production environments.}
\item{Built CI/CD for baremetal configuration of the Hydrahost datacenter and internal services using Gitlab, Ansible, and Vault.} \item{Contributed to Encore, a tool for provisioning datacenter systems, including backend systems supporting the Brokkr marketplace. This tool automates deployment of all self-hosted compute and software, removing the need for dedicated infrastructure engineering.}
\item{Combined automation from these pipelines to create a combined cloud and baremetal infrastructure that is defined by code.} \item{Defined and automated secrets management for deployment automation using Vault and Gitlab. This minimized, standardized, and secured the configuration process for software deployments by providing a single source of truth for all configuration within each environment, and securing those secrets with short-lived, pipeline-specific auth tokens.}
\item{Built custom build environment containers using docker to define and normalize pipeline and development environments.} \item{Defined development lifecycle and release standards and SOC2 production change compliance standards. Implemented across all projects, minimizing uncertainty around the software release cycle and security compliance.}
\item{Wrote Gitlab CI/CD library implementing lifecycle, allowing devs to maintain their own pipelines in a few lines by including the relevant jobs, greatly reducing overhead for developers.}
\item{Developed CI/CD library to support a flexible list of devops tools, esp. Ansible and Terraform. This allowed us to swiftly clear blockers if they involved the need to move to new software.}
\item{Greatly simplified pipelines by releasing a series of pre-configured containers, providing, along with the pipeline library, automatic, environment-specific configuration of Vault, SSH, TLS, and app dependencies. This allowed developers to manage software dependencies from a single source and keep project pipelines simple.}
\item{Captured managed service infrastructure in code. Along with code-based deployment of self-hosted services, this capstoned change controls across all production components, managed with Gitlab. This cleared our greatest blocker toward SOC2 compliance.}
\item{Identified business functions, created automation to perform them, and built them into continuous delivery as system and integration tests, to generate confidence in deliverables from the leadership and product points of view.}
\item{Built custom Terraform provider for Hydra compute services based on the OpenNebula API.} \item{Built custom Terraform provider for Hydra compute services based on the OpenNebula API.}
\item{Automated business functions on our platform to make product reliable and consistent when provisioning customers.}
\item{Developed system and integration tests, incorporating business function automation, and built them into continuous delivery to generate confidence in deliverables from the business POV.}
\item{Encoded IaC standards in continuous integration and deployment to ensure all production platforms remain reliable and consistent.}
