My experience
Filetable runs on a Kubernetes cluster in Switzerland: deploys in the middle of the day, two versions side by side, workers added on demand. Before that, CYSEC's services.

The challenges
- Launch fast, then last: SaaS, AI, and the moment to own your stackVercel, Supabase, Trigger.dev and AI let you launch a product in a weekend. But there comes a point where running your own stack costs less, and where you need an engineer in charge.8 minEssays
- Slow queries: from symptom to cause, without guessingMeasuring every query without slowing the app down, recognising three shapes, and four real cases where the culprit was not the one we expected.5 minFiletable
- Deploying in the middle of the day: two versions, one database, open tabsFor a few minutes, the old and the new version run side by side on the same database. And an open tab can stay on the old one for days.6 minFiletable
