Colin Chartier is the co-founder and CEO of LayerCI. LayerCI speeds up web developers by providing unique VM-like environments for every commit to a codebase, which enables developers, product managers, QA, and other stakeholders to preview code changes extremely quickly and removes the need to spin up a local environment to showcase demos. This enables interesting workflows like designers signing off on pull requests.

Colin was previously the CTO of ParseHub and a software design lecturer at the University of Toronto.

The focus of this episode was on developer productivity, management of a CI system and company, and even a little bit of cryptocurrency mining.
