Script to Deploy Kubernetes Clusters

https://github.com/OpenSource-THG/k8s-on-openstack
We needed to develop a new tool to help dev teams rapidly create their Kubernetes clusters deployed onto OpenStack. We used Pulumi as the infrastructure-as-code tool. However, the whole thing could be converted easily to Terraform.

In the past, single shared clusters were provisioned, which was deemed to not meet the requirements of dev teams that were becoming geographically dispersed and needed access to their clusters. This meant we needed the proper tooling to build clusters rapidly.

Deploying Teleport to OpenStack via Pulumi

https://github.com/OpenSource-THG/teleport-gcp-example
To reduce the number of identity providers and VPN connections needed, I researched using Teleport to provide secure and audited access to resources in OpenStack (VMs and Kubernetes cluster).

I planned, designed, and implemented the solution from inception to deploying on production infrastructure as a security research project.

The full write-up is not yet published.

Warehouse Management System

https://medium.com/thg-tech-blog/dynamically-building-build-servers-a6e785655834
At THG, I was a key contributor to the development of an event-driven warehouse management system (WMS). The WMS was developed primarily in Java with Spring, along with some microservices written in Scala and Kotlin.

I was heavily involved in the infrastructure management, including AWS EC2 instances along with Route53 for DNS, S3 for docs, DynamoDB and RDS for state, and Lambda.

I worked in CloudFormation and Ansible for deployments, Jenkins for CI pipelines, and core Java, Scala, and Kotlin for application features.

As a senior engineer, I was very involved with mentoring the junior staff about AWS practices and was a key member of the team that migrated the stack from AWS to OpenStack.
