The Architecture Behind a One-Person Tech Startup (2021)


As grandiose as the title of this article might sound, I should clarify we’re talking about a low-stress, one-person company that I run from my flat here in Germany.

Business-wise it's still in its infancy ( I launched six months ago update: it's been acquired), but it has grown rather quickly for my own expectations, especially as I originally built it for myself as a Django app using SQLite on a single tiny VPS. On one hand I leverage an in-memory Least Recently Used (LRU) cache to keep frequently accessed objects in memory, and I’d benefit from zero network calls (pure Python, no Redis involved). However, as a project grows, like Panelbear, I move the database out of the cluster into RDS, and let AWS take care of encrypted backups, security updates and all the other stuff that’s no fun to mess up.
