A staff engineer's journey with Claude Code

Does anyone have a link to a video that uses Claude Code to produce clean robust code that solves a non trivial problem (ie not tic tac toe or a landing page) more quickly than a human programmer can write? I don’t want a “demo”, I want a livestream from an independent programmer unaffiliated with any AI company and thus not incentivised to hype.

I want the code to have subsequently been deployed in production and demonstrably robust, without additional work outside of the livestream.

The livestream should include code review, test creation, testing, PR creation.

It should not be on a greenfield project, because nearly all coding is not.

I want to use Claude and I want to be more productive, but my experience to date is that for writing code beyond autocomplete AI is not good enough and leads to low quality code that can’t be maintained, or else requires so much hand holding that it is actually less efficient than a good programmer.

There are lots of incentives for marketing at the grassroots level. I am totally open to changing my mind but I need evidence.

Forget a livestream, I want to hear from maintainers of complex, actively developed, and widely used open-source projects (e.g. ffmpeg, curl, openssh, sqlite). Highly capable coding LLMs have been out for long enough that if they do indeed have meaningful impact on writing non-trivial, non-greenfield/boilerplate code, it ought to be clearly apparent in an uptick of positive contributions to projects like these.

But if you do professional development and use something like Claude Code (the current standard, IMO) you'll quickly get a handle on what it's good at and what it isn't. I think it took me about 3-4 weeks of working with it at an overall 0x gain to realize what it's going to help me with and what it will make take longer.
