Over the past few months I’ve been building a real-time crypto options volatility surface system from scratch.

At a high level, the idea sounds fairly straightforward:

ingest live options market data

maintained smile state per expiry

periodically recalibrated an arbitrage-aware SVI surface

streamed live updates to a frontend dashboard

It all ran on a medium EC2 instance.
