Jan-Marlon Leibl

19-year-old software developer from Bremen

I'm from Bremen, where I finished a three-year software development apprenticeship. I build things I want to use myself. At the moment, that is Finny: an app that keeps receipts and purchase details together. It reminds me before a warranty runs out. I usually work with PHP, TypeScript, and React. I also run a Proxmox node and look after my home network.
