I work at a FAANG. Professionally, I have had almost no luck with it, outside of summarizing design docs or literally just finding something in the code that a simple search might not find: such is this team's code that does X?

May I ask what you're working on?

It's been great - I work on a lot of projects that are essentially prototypes, to test out different ideas. It's amazing for this - I can create web apps in a day now, which in the past I would not have been able to create at all, as I spent most of my career on the backend.

I use it all the time now, switching between claude code, codex, and cursor. I prefer CC and codex for now but everyone is copying everyone else's homework.

I do a lot of green field research adjacent work, or work directly with messy code from our researchers. It's been excellent at building small tools from scratch, and for essentially brute forcing undocumented code. I can give it a prompt like "Here is this code we got from research, the docs are 3 months out of date and don't work, keep trying things until you manage to get $THING running".

Even for more production and engineering related tasks I'm finding it speeds up velocity. But my engineering is still closer to greenfield than a lot of people here.

I do however feel less connected to the code, even when reviewing thoroughly, I feel like I internalize things at a high level, rather than knowing every implementation detail off the dome.

The other downside is I get bigger and more frequent code review requests from colleagues. No on is just handing me straight up slop (yet...)

This is wild. I’m on the other end.

I’ve probably prompted 10,000 lines of working code in the last two months. I started with terraform which I know backwards and forwards. Works perfectly 95% of the time and I know where it will go wrong so I watch for that. (Working both green field, in other existing repos and with other collaborators)

Moved on to a big data processing project, works great, needed a senior engineer to diagnose one small index problem which he identified in 30s. (But I’d bonked on for a week because in some cases I just don’t know what I don’t know)

Meanwhile a colleague wanted a sample of the data. Vibe coded that. (Extract from zip without decompressing) He wanted randomized. One shot. Done. Then he wanted randomized across 5 categories. Then he wanted 10x the sample size. Data request completed before the conversion was over. I would have worked on that for three hours before and bonked if I hit the limit of my technical knowledge.

Built a monitoring stack. Configured servers, used it to troubleshoot dozens of problems.

For stuff I can’t do, now I can do. For stuff I could do with difficulty now I can do with ease. For stuff I could do easily now I can do fast and easy.

Your vastly different experience is baffling and alien to me. (So thank you for opening my eyes)

I am getting disproportionately good results with the models by following a process: spec -> plan -> critique -> improve plan -> implement plan.

If I may "yes, and" this: spec → plan → critique → improve plan → implement plan → code review It may sound absurd to review an implementation with the same model you used to write it, but it works extremely well. You can optionally crank the "effort" knob (if your model has one) to "max" for the code review.

I keep hearing “Claude creates subtle bugs”, but how is that different than people engineers? I’ve never worked in a bug free codebase

Everybody produces bugs, but Claude is good a producing code that looks like it solves the problem but doesn't. Developers worth working with, grow out of this in a new project. Claude doesn't. An example I have of this is when I asked Claude to copy a some functionality from a front-end application to a back-end application. It got all of the function signatures right but then hallucinated the contents of the functi…

> Developers worth working with, grow out of this in a new project. Claude doesn't.

There is no way this is true. People make fewer bugs with time and guidance, but no human makes zero bugs. Also, bugs are not planned; it's always easy to in hindsight say "A human would have literally copied the original lookup map," but every bug has some sort of mistake that is made that is off the status quo. That's why it's a bug.

I'm always skeptical to new tech, I don't like how AI companies have reserved all memory circuits for X years, that is definitely going to cause problems in society when regular health care sector businesses can't scale or repair their infra, and the environmental impact is also a discussion that I am not qualified to get into.

All I can say for sure is that it is absolutely useful, it has improved my quality of life without a doubt. I stick to the principle that it's here to improve my work life balance, not increase output for our owners.

And that it has done, so far. I can accomplish things that would have taken me weeks of stressful and hyperfocused work in just hours.

I use it very carefully, and sparingly, as a helpful tool in my toolbox. I do not let it run every command and look into every system, just focused efforts to generate large amounts of boilerplate code that would require me to have a lot of docs open if I were to do it myself.

I definitely don't let it read or write my e-mails, or write any text. Because I always loved writing, and will never stop loving it.

It's here to stay, because I'm not alone in feeling this way about it. So the staunch AI-deniers are just wasting their time. Just like any other tech, it's going to be used against humans, against the already oppressed.

I definitely recognize that the tech has made some people lose their minds. Managers and product owners are now vibe coding thinking they can replace all their developers. But their code base will rot faster than they think.

I had a couple of nice moments, like claude helping me with rust (which I don't understand) and claude finding a bug in a python library I was using

Also some not so nice moments (small rust changes were OK, but with a big one claude fumbled + I couldn't really verify that it worked so I didn't merge to code to master even when it seemingly worked)

I think it really helps to break the ice so to say. You no longer feel the tension, the pain of an empty page. You ask claude to write something, and improving something is so mentally easier

Also I mostly use claude as a spell checker / linter for the projects I'm too lazy to install proper tools for that. vim + claude, what else would you need

Luckily my company pays for the subscription, speding personal money on LLMs (especially on US LLMs) would feel strange for some reason. Ideally I want to own an LLM, have it at home but I am too lazy

Can you give a little more detail how you execute these steps? Is there a specific tool you use, or is it simply different kinds of prompts?

I follow a very similar workflow, with manual human review of plans and continuous feedback loops with the plan iterations

See me in action here. It's a quick demo: https://youtu.be/a_AT7cEN_9I

Experience depends on which FAANG it is. Amazon for example doesn't allow Claude Code or Codex so you are stuck with whatever internal tool they have Meta, despite competing with these, is open to let their devs use better off the shelf tools.

I work at aws and generally use Claude Opus 4.6 1M with Kiro (aws’s public competitor to Claude Code). My experience is positive. Kiro writes most of my code. My complaints: 1. Degraded quality over longer context window usage. I have to think about managing context and agents instead of focusing solely on the task. 2. It’s slow (when it’s “thinking”). Especially when it’s tasked with something simple (e.g., I could…

Context degradation is a real problem.
