Software architect & developer · Allerød, Denmark
Jeppe Lillevang Salling
I write software and build the platforms it runs on. On engagements I'm usually the architect or lead developer, working in Java, Keycloak and Kubernetes with the open-source stack around them, mostly for Danish public sector and enterprise.
Independent, with engagements through Darize (formerly Globeteam), where I lead the platform and cloud team as Platform Lead.

Off the clock
I live in Allerød, about 30 km north of Copenhagen, with my wife Helle and our three kids: Søren, Emilie, and Marie. When I get a moment to myself it goes to the homelab, 3D printing, security tooling, or sketching out new language designs. What I'm focused on right now is on the now page.
