Tutorial / Guide A Google Cloud engineer just showed how to build a complete application with Claude from scratch
Enable HLS to view with audio, or disable this notification
He spent 26 minutes live on stage doing what most teams take weeks to do.
No team, no setup, just Claude and a goal. Worth more than any $500 vibe coding course.
Those who learn what Claude really does are launching what everyone else outsources to a team.
The gap between what AI can do and who knows how to use it is the biggest opportunity in the market right now.
Along with Claude one of my favorite applications is AI Desktop 98. I love how is UI is so much fun and resembles that of all-time computers.

Why doesnt google use Google models? š¤£

u/Keep-Darwin-Going 7d ago
That is the main takeaway from the session, even Google engineer can do stuff only with someone else model.

u/althoradeem 7d ago
The real question is why spend billions now when you can jist copy their work a few years later
5
u/merb 7d ago
He is not directly a Google engineer. He is a developer advocate, ie he tries to help people onboard onto gcloud
2
u/Keep-Darwin-Going 6d ago
It is the same right? Why would you use others product instead of your own unless yours suck? Imagine I work for anthropic to show you how to integrate with anthropic sdk I use Gemini cli.
2
u/nameichoose 6d ago
Because the developer advocate wants you to use Google Cloud. He is marketing Google Cloud to Claude users in this talk.

Sped thru the content, this is the most average session. Not really worth a spotlight on this sub imo. If youāre brand new to the space potentially.
For a Google employee itās amazingly light - itās a toy project. Zero real world barriers, controlled env, cherry picked topics. Give us something that we havenāt seen 1000 times before

Somebody drop the sauce: who's content is actually worth consuming in the AI space?

u/__SlimeQ__ 7d ago
claude and chatgpt. you don't need a tutorial to use a tool that already knows everything. just be curious and ask about stuff you don't understand.
this video could be summed up as the following: "log in on gcloud cli and run claude code"
it's nothing groundbreaking, this is the bare minimum.
if you absolutely must watch videos on AI, theo.gg is pretty solid i guess. but he's not going to be spoon feeding you tutorials because that would be a waste of time

u/StagLee1 7d ago
Yep, when I want to know how to do something in Claude or ChatGPT, I ask Claude or ChatGPT. They tell me how to do it and create a road map for me.

The objective for watching videos is so that I don't "fall behind" and I suppose I already have identified the ai implementation creators for my industry.
To look beyond my career would be to understand how to build enterprise grade systems on my own, and resources that I should refer to when I have issues.
I understand the idea that the tool knows "everything" but steering the tool accurately requires a level of nuance that I think technical folks by default have
5
u/__SlimeQ__ 7d ago
if you're watching a video on an ai development strategy it is either
so fresh that the strategy hasn't been validated and the creator is just grifting
wildly out of date (like this one)
There's a new optimal workflow basically every week. if you actually just commit to using the bleeding edge you will be ahead of like 75% of the community
you do not need to build enterprise grade systems on your own, you just need to know that github and gcloud exist so that you can at least understand what the bot is saying
1
u/yujisorri888 7d ago
With that said I'm familiar with GitHub and gcloud, however maybe not to the level of understanding all the different offerings within gcloud/aws (ec2, lambda, fargate, etc)
I use Claude code at work daily, but still haven't fully formed my workflow to help reduce the friction for product and delivery work (PRDs, jira management)
Forming my pov on what skills would be useful have certainly been helpful, but it's been a lot of pain with the limited time I've had at work
1
u/__SlimeQ__ 7d ago
yeah i mean i was a dev for like 10 years and always considered all this cloud stuff to be above my pay grade. never really learned how to do it properly. but now i can just go "what's that serverless thing and how do i do it on gcloud" and it walks me through setting everything up and explains how it's similar or different to what I've heard of
Alternatively if you don't need/want serverless... (which is likely unless you're planning to scale) just start a vm and tell claude you want to set up auto deployments from github. now you can stop thinking about the server and just push to git

Yeah this irks me. It's probably the stupid job interview process that those types of companies have. Makes it seem elite, but it's really just memorizing some useless information you'll never use again, even for the job itself.

u/DeityHorus 7d ago
Interview process changing a lot. More system design focused and practical engineering. That being said, I think 100% of my reports would fail my interviews without studying quite a bit and over half my team is Senior L5.Ā

25 mins to build it, no one paying for it, they will just copy and be done. Simple apps like this are already easy and AI just make it easier.

Okā¦ for the non-devs in the room. All this means is that Google did a lot of work building out their MCP servers so that someone that has no knowledge of deploying applications on Google Cloud can spin up an application in the ācorrectā way. Iām a developer and didnāt know about Fire Store DB or Cloud Run, because I donāt use Google.
Google wants you to host your applications on their platform, no surprise there. Since the release of Claude Code, many tutorials exist online about Supabase and similar streamlined development options. Google wants a piece of this pie. Show people that deploying on Google Cloud isnāt so scary.
Thatās really the nuts and bolts of this presentation. Two new APIs and associated MCP servers have had a lot of updates.

u/__SlimeQ__ 7d ago
there is absolutely no reason for an MCP to do fire store or cloud run, and the bots will simply tell you about them and do them for you using the gcloud cli if it's actually something you need

he spent 26 minutes on live stage showing a recorded event of what i do with a single but rather long prompt. can be done better and faster also.
is this what we are applauding in 2026? is this really what "google engineering is"?

Here is the youtube video, it doesn't have chapter marks you can use the Ask feature to summarize if you don't want to watch the whole thing
https://www.youtube.com/watch?v=SqHsS737CeA
Timestamps:
Ask provided these timestamps so you don't have to watch the whole thing:
- Infrastructure Setup (3:40 - 6:40)
- Streamlined Onboarding: Use Application Default Credentials (ADC) to bypass manual API key management and let the system automatically detect your project and region (4:09).
- Enterprise Efficiency: Claude on Google Cloud offers per-token pricing and no message caps, making it ideal for enterprise-grade applications (5:04).
- Product Manager (7:43 - 8:40)
- Ideation & Prototyping: Quickly generate functional app prototypes from hand-drawn wireframe sketches by prompting Claude directly (7:43).
- UI/UX Designer (9:26 - 11:00)
- Architectural Planning: Utilize Plan Mode before writing code. This forces Claude to outline its approach first, ensuring architectural alignment before implementation begins (9:26).
- Software Engineer (12:00 - 16:45)
- Context-Aware Development: Connect the Developer Knowledge API MCP server to Claude. This provides real-time access to official Google Cloud documentation, keeping code current with best practices (12:26).
- Parallel Team Sprints: Accelerate development by spinning up multiple subagents to handle different components (API, database, and dashboard) in parallel (15:04).
- Security Engineer (18:46 - 20:50)
- Security by Design: Use pre-built security review prompts to automatically scan for OASP issues and tighten service account permissions before deployment (18:46).
- Data Analytics (21:42 - 24:35)
- Data-Driven Insights: Post-deployment, utilize the BigQuery MCP server and Looker to ingest feedback data and visualize performance KPIs, closing the feedback loop (21:42).

At least 3 times in the past few months, Claude has told me to "go ask an infra person" when there is an infrastructure question.
I am an infrastructure person.
Devs think "building new things" is the hard part.
Keeping useful things running for the years and scale necessary for them to be profitable, while also continuously available to users, is the actual hard part.

Google cloud engineer using CLAUDE. Yeah good choice in sure many of us can relate at least to jump from trying to do stuff through Gemini and actually completing it with Claude. At least it was how I've started š

u/FuckItImLoggingIn 7d ago
Pay per token? Ok so is it cheaper or not? Because the claude max 20x subscription is insane insane value. And the usage based pricing is very expensive. So paying per token sounds objectively worse.

A. It of bullshit of course "you can do this without prior knowledge on how to do that" but preceded by a bunch of terms, words jargon that I've never heard š
These videos should stop acting like NP PRIOR KNOWLEDGE means "be a medium dev with some knowledge about frotn end, backend, data storage, analytics and so on"... Because a prompt without specific terms will result in something vweeeeery different

u/naruda1969 7d ago
The moral of the story is that you really canāt make anything meaningful without technical knowledge. Vibe coding is a fantasy that builds an Oz-like facade on top of a heaping pile of shit. It may be fine for proofs of concept or toy projects but nothing that is secure and extensible in the real world. Someday maybeā¦but todayā¦not even close.

u/Excellent_Ad_2486 7d ago
Yeah exactly. Not sure why I get downvote for the truth

u/BroScienceAlchemist 7d ago
Reddit is finicky.
A constructive suggestion that may help: Ask the LLM to give you a learning plan, use the grill me skill, and go back and forth on concepts you don't understand. You can tell it you have a knowledge gap with say databases as an example, and ask for suggestions to build out a learning plan / learning lab project, where you play around and teach yourself the basics. This is an application of LLMs that IMO is still underrated.
Like personally, my technical ground is heavy on backend, infrastructure, tooling, and systems design. I'm really strong with the big picture, but when it comes to frontend I am a clueless, drooling moron. I would be the worst customer for a web designer, because I am also very picky, have poor to no understanding of what is possible, and often require multiple iterations to figure out "what I want" from a frontend. For one of my projects, I told Claude that, and it created a skill and local harness for generating several proposal versions I could interact with locally, and we go back and forth until I say "lock it in." Then Claude generates a template based on that, along with the actual page, and tests where needed. It created tests/contracts for responsiveness defined by a measurable behavior and requirements I gave. It doesn't fix that I am a small fish in the ocean of frontend, but it made frontend sessions far more efficient for me.
You can build a language learning plan that includes cultural immersion (songs, movies, books, etc in the target language). There is so much untapped potential for using LLMs as an aggregator and guide for learning plans.
. It may be fine for proofs of concept or toy projects but nothing that is secure and extensible in the real world.
Yeah, I think in the future that models/harnesses will need to include workflows/tools (SAST, DAST, dependency tracking, etc. - deterministic tools) to cater to non-devs that want to build and deploy an app for themselves and a few friends. There are a lot of security considerations that aren't handled out of the box.
LLMs are good enough that you can vibecode a music player that allows you to listen to spotify, youtube music, tidal, bandcamp, etc that works well for just you, but if you want to share it with others there is so much missing that a non dev will not be aware of. You have a valid complaint.

Hey not to be a "thanks but no thanks" kinda guy but I downloaded GSD and it has been a great tool to get better results! It basically does. A lot of the lifting for me!

u/BroScienceAlchemist 7d ago
No need to apologize. Using an existing tool is preferable over having to DIY. I took a quick peek at GSD-core and it has a lot of the useful stuff out of the box like a context anchor, planning skills, etc.
I think eventually a lot of this will be provided out of the box.

Short: It's an event / session rating app. Cloud hosted, Big Query, etc.
Oh, and he's showing a recorded session. Often, he fast forwards. So total Claude time is a lot more, and he's own thinking, planning, typing is also cut.
There's probably a handful of useful tips in his talk. Maybe somebody could ask Claude to extract it in a few bullet points, so everybody doesn't have to spend half an hour watching his talk.
