New blog.
If you want to start Freelancing and build client relations then a Must read.

[FTB @v_nefodov]

A STUDENT FROM CHINA BUILT A WALL OF 25 REAL PHONES AND TURNED IT INTO $2,700 A MONTH. NOT A SCAM. A QA TESTING LAB.

Not crypto. Not dropshipping. Not a phone farm for views.

App developers need their software tested on real devices before launch. Not emulators. Not simulators. Actual phones with actual screens, actual chips, actual quirks that only show up on hardware. Most small dev teams cannot afford a dedicated QA department, so they skip real-device testing and ship bugs straight to their users.

He saw the gap and built a rig of 25 physical Android phones mounted on a single monitor wall, all running simultaneously, all mirrored to one screen he can see at once. A client sends him an app build. He pushes it to all 25 devices across different models, different Android versions, different screen sizes. Each phone runs the app live while he watches every screen in a single grid.

Claude handles the analysis layer. It reads the screen output from each device, flags crashes, layout breaks, and performance differences between models, and compiles a structured bug report the client can hand straight to their dev team. What used to take a QA team a full week now takes him a few hours across one wall of phones.

Pause the video at
0:04 and look at the bottom left screen. Did you notice something?

That is device 19, already flagging a layout issue that does not show up on the newer models above it. Older hardware, different rendering, bug caught before a single user ever saw it.

App studios were paying QA agencies $3,000 to $6,000 for a full device-compatibility pass. He charges $400 per app and turns it around in a day.

No office. No QA team. No emulator subscription pretending to be real hardware.

Just 25 phones, Claude reading every screen, and one student turning a wall of devices into $2,700 a month.

🔖 Save This: 10 Websites That Explain Things Beautifully

The internet is mostly noise. These are the rare websites that take something complicated and explain it so beautifully it just clicks.

Some of the best places I've found for learning through visuals, interaction, data, and storytelling - spanning software, AI, music, economics, design, and human behavior.

If you're the kind of person who can't stop asking how does this work? or why is it built this way? — this list is for you.

No textbooks.
No fluff.
Just things explained so well they finally make sense.

and please skip the "build an ai agent in 10 minutes" videos
build something, watch it fail, then figure out why.

@asishcodes I think take a pg for now after that we can explore to get a better one
As one bhk in that area with that budget is rare or costly bro

Being average is risky now,

Because the market is faster

AI has stopped being a feature and started being the foundation.

We're excited about a new wave of startups rebuilding software, services, and silicon— and pushing AI into the physical world.

If you’re an engineer and have been told “you’re doing too much”

I’m sorry to say, but it’s time to leave.

Come join a place where we actually prefer a bias for action 🚀
