Hey @beeme1mr thanks for the offer!

Happy to join and help out with the Python code base 🍻 I hope to also contribute to the Rust SDK over time, but I'm still quite new to Rust, so it will take a bit.

I maintained for roughly 2 years https://github.com/bridgecrewio/checkov till I changed my employer, but I'm still helping out from time to time. Currently I'm maintaining https://github.com/salesforce/cloudsplaining and the underlying project https://github.com/salesforce/policy_sentry. Other than that contributing to all kinds of random projects, wherever I'm interested in 😄

Hey @gruebel, if you have already, I would encourage you to join the CNCF Slack. We have a few channels that you may want to join #openfeature and @openfeature-rust.
