as I scale my trade infra, I increasingly become aware of how important it is to have your code documention in order across all processes such as:

> data fetching, cleaning, processing and storage
> signal processing
> backtester
> live execution engine
> live trade data cleaning and storage
> external risk controls
> performance benchmarking

with enough detail so it doesn't become a mess every time there's an error.

don't neglect the boring part of producing clean code that you understand.

do not outsource your peace of mind to an LLM because it will eventually come back to bite you, and probably when you least can afford it to.
