# About Me

My name is Christopher Sardegna. I'm a Staff Software Engineer at Oscar Health, where I build healthcare claims pricing systems.

Before joining Oscar, I spent nearly seven years at Evernorth leading the design and implementation of its repricing engine. See my [resume](/resume/) for more about that work and the resulting patents.

## Technology

I mainly work in Rust, Python, and Go.

I maintain [imessage-exporter][0], a tool for reading, backing up, and exporting iMessage data.

I also maintain:

- [crabapple][1]: reads files from encrypted iOS backups
- [crabstep][2]: decodes Apple's typedstream format
- [fleetcom][3]: supervises concurrent shell commands

I write about reverse engineering, performance, and debugging on my [blog](#blog).
