19, software developer from Bremen

I'm a software developer from Bremen. After finishing a three-year apprenticeship here, I started building the tools I wanted for myself. My current project is Finny, an app that keeps receipts and purchase details in one place and warns me before a warranty expires. Most days I work with PHP, TypeScript and React. Away from that, I run a Proxmox server and usually find something else to fix in my home network.

Projects

Finny receipt and warranty app

With Finny, my receipts, purchase details and warranties finally live in one place. It reminds me before I miss an expiry date.

Ventry expiring file sharing

Ventry lets me send a file without keeping it online forever. The link and the file disappear when the time is up.
