Harrison Muskat

Ocado Technology Group (6 River Systems) as a Staff Software Engineer, with DevOps focus

What I Do For Work

• Cloud infrastructure design and development supporting large customers and internal teams alike across microservice-based cloud applications and IoT systems backing huge fleets of warehouse robots

• Node.js application development with a focus on web APIs and productivity-focused CLIs

Some stuff I've Built (or helped build)

• Authorization/Authentication system for 6 River Systems' (6RS) software, using the NestJs application framework and PassportJs to support auth strategies that include JWT-based authentication, SSO, and OIDC authentication via Google, Azure, or Auth0

• A NestJs-based application to manage Google Cloud environments and GKE infrastructure; collaborated to build this out while converting all Kubernetes-related Terraform to use Kubernetes and Google APIs. This change allowed our deployment speed to go from 15-20 minutes to 5 minutes, on average.

• Wrote a CircleCI orb to convert outdated Bash scripts into simple, testable orb jobs and commands; the orb manages many parts of our CI/CD process including versioning, image building and deployment, and deployment of images to GKE clusters

• Terraform infrastructure-as-code to support single applications and microservices running in GKE, using backends both in CloudSQL (Postgres) and SQLite; created small modules in order to simplify the implementation of our Terraform and make it reusable
