I'm Rob and I want to share what I've built - a solid ledger behind simple API: https://decimals.app
The ledger is a key piece of any financial system and is easy to get the design wrong, resulting in troubles for making sure money movements are adding up.
I took a lot of inspiration from good designs from Square, Uber, and others for the scalability and security aspects. And on the usability side, I applied many concepts from the Ledger CLI, making it very easy to use.
I'm really happy I get to show this to you all, thank you for reading about it! Please let me know your thoughts and questions in the comments (The sample code on the landing page is not working, I'm fixing it).
