Hi.
I'm Johan

Blog

I'm Johan Fagerberg, a developer with an interest in automation, user/developer experience, and online privacy. I enjoy working on tools that make daily chores easier, more intuitive and less cumbersome.

When I have the time, and something interested to share, I write articles on my blog.

Open Source Projects

Below are some of the open source projects I have been a leading developer on.

Work History

2024 +

DevOps Engineer at KMD

Managed the cloud infrastructure, CI/CD processes and developer interfacing across multiple projects, supporting the application teams in delivering high-value solutions without worrying about the underlying server management.

Primarily worked on transitioning our in-house DevOps framework to a Kubernetes-first setup, and supporting our developers in adapting their workflows and application code to containers.

2022 - 2023

RPA developer at Odense University Hospital

Headed the team responsible for process automation across a workforce of 8000+ healthcare workers. Responsible for projects ranging from bespoke applications and automation scripts, to work process optimization across the hospital.

In addition to the above, I put significant work into the team’s internal workflows, developing custom tools, improving internal and external documentation, and working with suppliers to triage and fix issues as they occured.

2015 - 2019

Frontend developer at CleanManager

Maintained and developed a web application consisting of multiple interwoven SPAs, and the related backends for each. Participated in planning, implementing and evaluating new features in collaboration with company founders and customers, with a strong focus on value generation.

Spearheaded the effort to modernize our codebase by transitioning from a custom-written frontend framework to one built on React - an up-and-coming framework at the time.
