About 121&0n2

> Tor E Hagemann: Software Consultant (manager)

Practical and efficient Chief Technology Officer, employing over a decade of relevant experience from large firms AND start-ups, to ship SaaS from concept into production. Typically, I lead from a position toward the back-end of the full-stack, moving Product to the forefront.

Partner with me to pilot your greenfield systems, as well as to (p)re-architect solutions and boost the value of code produced by existing teams, esp. through Cloud workloads on Kubernetes (k8s) or containers (Docker, podman) using HashiCorp tools, Golang, C/C++, Python, TypeScript, NextJS (and more) on any platform, including GCP/AWS or local hardware.

What is onetooneandon.to?

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

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

The formula: your company’s Data + my Services + Time = Working products that users will love using.
