My experience
Filetable stores everything in it: customers' tables, relations, filters, with migrations the live version can handle. Also at Branchlate, Swelv, OneDoc and ID Quantique.

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
- Queues and priorities: orchestrating thousands of documents with TemporalA document goes through a dozen steps of OCR, AI and SQL. The real challenge is not chaining them, it is deciding who goes first.7 minFiletable
- A RAG without vectors: the model finds its own booksEvery month, five books picked for each reader. The model invents no title: it queries the catalogue with tools, and code checks everything.6 minSwelv
