Dan has been working on and worrying about containers since 2015 as an engineer and manager. He started projects like [Minikube](https://github.com/kubernetes/minikube), [Skaffold](https://skaffold.dev/), and [Kaniko](https://github.com/GoogleContainerTools/kaniko) to make containers easy and fun, then got so worried about the state of OSS supply-chains he partnered up with Kim and others to found the [Tekton](https://tekton.dev/) and [Sigstore](https://sigstore.dev/) projects to make it easier to build and use containers securely; as well as [SLSA](https://slsa.dev/) to create a common language for software security and supply chain integrity. He has been involved with the [Cloud Native Computing Foundation](https://cncf.io/), chaired the [Continuous Delivery Foundation](https://cd.foundation/) technical oversight committee, and sits on the governing board and technical advisory committee for the [Open Source Security Foundation](https://openssf.org/).
