Hi 
Nice to see more people join ^^
Did you follow the v2 ecosystem project? It’s currently focusing most of the work.
It depends whether you want to level up your Rust or benefit from your Python / Typescript experience.
- Ğcli (forum) (repo) is a Rust command line client for Duniter v2 which is nice to begin with
- Tikka (forum) is a Python v2 client developed by @vit which already has a lot of feature
- Cesium v2 (forum) is a Typescript + Angular rewrite of Cesium in the v2 ecosystem and could use some help to go beyond the proof of concept stage
And there is a lot of tooling, but not as easy to start with.
