How I work
- 01
I use it first
Every project started with a problem of my own: a full disk, my calendar, the images for an online shop. If it does not work for me, it is not finished.
- 02
Secure by default
No open ports: Cloudflare tunnels and Access, end-to-end encryption where the data is sensitive, and a strict CSP.
- 03
Warn me before it breaks
Daily backups, automated tests and a watchdog that lives outside the server and messages me on Telegram.
Let's talk
If one of these projects caught your eye or you have something in mind, drop me a line. I answer myself, no forms in between.
