Scaling SQLite to 4M QPS on a single server (EC2 vs Bare Metal)

Scaling SQLite to 4M QPS on a single server (EC2 vs Bare Metal)

Expensify has an unusual technology stack in many ways.  For example, we don't use DNS internally — just configuration-managed /etc/hosts files — and it works great.  Similarly, we only make limited use of AWS — instead hosting our own hardware for the web and database layer — and it works great.  But most surprising of all is that we don't use MySQL or Postgres — instead using none other than SQLite — and it works great.

CEO Friday: Why we don’t hire .NET programmers

As you might know, we're hiring the best programmers in the world.  Sure, everyone says that.  But my coders will beat up your coders, any day of the week.  For example, Mich is barely 5 foot tall, but is a competitive fencer.  Witold is a 6'3" former professional hockey player.  Nate practices knife fighting for fun.  And they're pretty decent programmers, too.
