I'm currently contributing to Node.js and V8 full-time, working on diagnostics-related features. In the last year:
- I introduced
executionAsyncResource() - I contributed to parts of
AsyncLocalStorage - I create the incoming
diagnostics_channelfeature - I significantly improved the performance of async_hooks in promise-heavy applications by avoiding GC-tracking of promises where no destroy hook is in-use
- I fixed PromiseHook support for thenables in V8, allowing context tracking with AsyncLocalStorage, or similar systems built on top of async_hooks, to correctly propagate context when using thenables, which are commonly used in database libraries
- I'm currently working on a rewrite of the PromiseHook support in V8 to use JSFunctions rather than C++, which eliminates many expensive barrier hops between generated code, runtime functions, and external C++. This should improve PromiseHook performance and therefore also async_hooks performance quite dramatically.
In the future, I hope to rewrite many parts of async_hooks to trigger lifecycle functions from within JavaScript, wherever possible, further eliminating barrier hops and being much friendlier to the optimizer in V8.
This would allow me to keep working on Node.js core full-time!

I'll give you two 12-hour days a week of contract/consulting time and spend all the rest of my time on Node.js and V8 work. I'll publicly promote your company as a primary sponsor of my Node.js and V8 involvement.
I reserve the right to decline if I dislike/disagree with what your company is doing. I suggest contacting me first to negotiate specifics before committing to this tier.
