• Provided technical advice for deployment of a latency sensitive service to an engineering team, providing detailed technical breakdowns of time taken to service their web requests

• Built an isolated replica of our production environment and performed load testing and analysis to support customer queries about our platform

Senior Cloud and Internal Tooling Engineer

• Worked with the engineering teams to understand their pain points and needs to produce a product roadmap for our internal tooling that maximised the value we could provide with the available time and people.

• Lead design, development and release of our new deployment system, which allows engineers to easily deploy their pull requests to production with processes running inside of Docker containers on top of Amazons ECS container scheduler. (http://bit.ly/deploysystem)

• Lead sessions explaining how Docker and container orchestrators work to ensure the engineering team understood what was happening when we migrated to our new deployment system.

• Maintain, improve and help engineers understand our Jenkins setup, most recently significantly improving build times by autoscaling our Jenkins secondary nodes based on the time of day. (http://bit.ly/jenkinsauto)
