Hi there! I'm Sean Collins and I manage DevSecOps teams and engineers!

What I'm looking for

Helpdesk turned developer turned operations turned leader. I have lived at every layer of the stack and can work with just about anyone. I've worked extensively with development teams, product owners, and traditional operations staff to help modernize workflows and deliver real world results. My passions revolve around automation, public cloud, and infrastructure as code. Outside of work, I travel, take pictures, attempt to write, and generally enjoy experiencing this complex world we live in.
