Josh Horn

I'm Josh. I build web apps, integrations, and data tools in Python and Django, mostly for the healthcare and insurance world.

For the last couple of years I've been the developer at a healthcare claims administrator, where my work runs from Django apps and SQL Server to X12 EDI files, Power BI, and the VMware boxes everything sits on. Outside of work I tinker with language models and run a small Kubernetes cluster at home.

I'm open to remote full-time roles and contract projects.
