> Tor E Hagemann: Software Consultant (manager)

Practical Chief Technology Officer, employing over a decade of relevant experience from large firms AND at start-ups, to ship software from concept into production. Typically, I work in a position toward the back-end of things, moving your product to the forefront.

Partner with me to pilot your greenfield systems, as well as to (p)re-architect solutions and "boost" the code produced by existing teams, esp. through containerized workloads using HashiCorp tools, k8s = Kubernetes, Docker, Golang, TypeScript, NextJS (plus more) on any Cloud/etc.

What is onetooneandon.to?

Essentially, it's my personal domain and brand of consulting work.

It is a name I use for all IP that is not connected to another entity, including open-source work and things where I retain ownership, so long as there is not another agreement to supersede that simple arrangement.

The formula: data + services + time = working products that users will love

The name derives from the abstract maths concept of a function, which has unique output for each given input. (and, vice versa)
