Your name 'grishka' looks familiar. I'm also an ActivityPub developer (https://quanta.wiki). What languages do you develop in, in case we can share code?

If you want to talk about sharing code or ideas on AP, https://socialhub.activitypub.rocks/ is the place to go.

(I'm there with my hn username. Building a decentralised professional social network-linkedin)

Java for the back end, TypeScript for the very lightweight front end.

BTW we have spoken before. You are the developer of Smitherene, the only other ActivityPub implementation in Java other than my Quanta platform.

Your code was very helpful to me getting my impl working!

I'm also doing the same: Java+TypeScript.

If you want to collaborate, I'm here:
