-We pride ourselves on shipping fast – sometimes too fast. In the past 12 months, our userbase has grown 5x, so it was time to take a step back and take a hard look at where we are burning cash, especially on the IT & infrastructure side.

-Key optimizations:
-
-- Google Cloud: Improved Firebase usage by 56%. Saved ~$7,450/month.
-- OpenAI: Replaced LLM-based checks with regex. Saved ~$900/month.
