from the author's mastodon post [0]

    I just published Fintech Engineering Handbook distilled from 6 years of tears, sweat and swears. 
    It’s a free ~25-page resource with various hints and patterns around handling money. 
    Tell me what you think!

other than that, peruse the commits on the source [1], or wait for the author to respond.
