Patrick Stephens

Over 20 years experience in software engineering, mostly in the defence domain at Thales. The last few years of this were focused on transformation first to containers then Kubernetes.

After Thales I worked on the cloud native team at Couchbase, working on their Golang-based Kubernetes operator. This included producing a custom Fluent Bit deployment for observability needs.

Calyptia (founded by the Fluent maintainers) then approached me to come work with them building out observability products before we were successfully acquired by Chronosphere. I then led the migration of all our infrastructure and SOC2 compliance before Chronosphere was again successfully acquired by Palo Alto. During this period I also became a core maintainer of the CNCF graduated Fluent project, primarily working on Fluent Bit.

I am now running an OSS consultancy for observability called Telemetry Forge leveraging our knowledge as well as working with customers in the defence domain again.
