Work History
Senior Site Reliability Engineer - GC Notify
Canadian Digital Service [CDS], ESDC

- Championed migration from Kustomize to Helm/Helmfile to provide better lifecycle management of workloads and support tools deployed to AWS Elastic Kubernetes Service
- Implemented secrets management solution for both infrastructure and Kubernetes workloads to ensure a single source of truth for environment secrets, and to increase ability to automate deployments.
- Implemented Kubernetes auto-scaling through Karpenter, designed performance tests, and tuned Kubernetes workloads, which increased performance 5 times, while also reducing compute costs.
- Automated upgrade of PostgreSQL from 11 to 15 in all environments using blue/green RDS deployment mechanism, resulting in 4 major version upgrades with no downtime.
- Conducted root-cause analyses after major incidents to identify areas for process improvement or technical enhancement opportunities.

Site Reliability Engineer
Digital Technology Solutions (DTS), ESDC
04.2018 - 07.2021
- Developed a DevOps maturity assessment matrix and evaluated delivery teams under the Old Age Security Service Improvement Strategy imitative. Created an action plan for these teams to gain short term wins that would free up cycles to address more difficult issues for the long term.
- Wrote a series of blog posts with a target audience of management and above to explain how cloud native and DevOps differ from traditional Government IT practices. These posts provided a balanced review of the benefits as well as potential pitfalls based on my extensive experience working in both environments.
- Built and deployed the Azure Application Service infrastructure used to host the Covid19 Benefits Finder, which Canadians could use to determine which benefits they were eligable for.
- Implemented the Human Resources Manager (HRM). The HRM was an open source product (Odoo) deployed to a purpose built Kubernetes infrastructure that provided a secure location for managers who could not access the ESDC network to store contact information for their employees.
- Promoted TBS' Open First policy by implementing a cloud native monitoring solution built on open source components (Graylog, Grafana, and ElasticSearch).
- Promoted agility and resisted vendor lock in by establishing a policy requiring all infrastructure code to be developed using Terraform instead of cloud service provider specific templates (ARM Templates or CloudFormation Templates).
- Created and deployed the first cloud spoke to connect to the ESDC Cloud Operation's hub. Provided feedback to the Cloud Operations team to better improve the onboarding process as well as ensuring that DevOps practices could be leveraged to their full extent within this model.
