## plans

- Here's my [project board](https://github.com/users/LarryRuane/projects/1/views/1), all plans tracked there
- Continue
- to build relationships of trust in the community, especially among developers
- reviewing PRs, and continue getting better at review
- to improve time management (working on most important things first)
- participating in and hosting [Bitcoin Core PR Review Club](https://bitcoincore.reviews)
- contributing to the PR review club section of the [Optech newsletter](https://bitcoinops.org)
- to attend in-person events when possible
- I'd like to take ownership and drive a significant improvement or feature, ideas:
- [thread fuzzing](https://github.com/LarryRuane/bitcoin/issues/5)
- [smoke test" network-level (multi-node) high-load stress-test fuzzer](https://github.com/LarryRuane/bitcoin/issues/4)
- something else?
- Definitely would like to create PRs for or adopt, and get merged:
- [Obfuscate database files](https://github.com/LarryRuane/bitcoin/issues/1)
- [Move fee estimator into validationinterface/cscheduler thread](https://github.com/bitcoin/bitcoin/pull/11775)
- [Split validationinterface into parallel validation/mempool interfaces](https://github.com/bitcoin/bitcoin/pull/12979)
- Get my existing unmerged PRs over the finish line
- Mentor at least one new developer
- After reviewing a difficult PR, consider creating a presentation like the [one](https://youtu.be/sQ05azzTp9o) I did for [PR26152](https://github.com/bitcoin/bitcoin/pull/26152)
