• Implemented Redis instance migrations across clusters in under 5 minutes.

• Built user friendly tooling for automated application failovers used during incidents and for infrastructure maintenance.

• Leveraged application metrics and ongoing incidents to make infrastructure deploys safer by implementing custom deploy strategies.

• Modernized the application platform infrastructure according to resiliency best practices by championing project to migrate 400+ services to newly created Kuberenetes clusters.

• Mentored new team members and interns to provide support as they ramped up to the tooling and processes used by the team.

Production Engineer, Cloud Platform

• Migrated multiple business critical applications to the new internal application platform.

• Reduced the impact of noisy neighbour using a custom Kubernetes controller to manage the creation of resource quotas, and limit ranges for application namespaces.

• Reduced support burden on the team by making it easier to debug deploy failures through improved error handling for invalid Procfile entries in Herokuish.

• Reduced container build times from 5 minutes to under a minute for configuration file changes by leveraging the container cache, speeding up deploys and making it faster to scale up applications.

• Built a user interface for developers to monitor application health and status without requiring knowledge of the inner workings of the platform or Kubernetes.

Production Engineering Intern

• Containerized & migrated multiple production critical services on to Kubernetes.

• Automated cluster creation and application bootstrap on Kubernetes through a CLI and a chat bot.

• Built an on-demand staging environment for developers to boot up standalone Shopify instances including database snapshots to seed the staging environment.

Shopify's Path to k8s

Presented a talk on building a platform as a service on top of Kubernetes and Google Kubernetes Engine. The goal was to share Shopify's best practices and start a discussion in the community to see how others are tackling similar challenges.

How we did it: One customer’s journey to modern infrastructure

Co-presented a session on the experiences of using containers and Kubernetes in production and lessons to keep in mind when undertaking such a migration.

Building Containers @ Shopify

Gave a talk on container building at Shopify and the tooling we used and built. The goal was to share our experiences and promote best practices across the local community.
