Master frontend skill by cloning these sites🎉
1. Netflix🎯
https://www.netflix.com/in/login?nextpage=https%3A%2F%2Fwww.netflix.com%2Fbrowse
When logged in Netflix is a pretty simple design. Horizontal rows, galleries, with a big featured banner.
2.Hulu🎯
https://www.hulu.com/welcome
Just like Netflix, the logged in experience in Hulu is pretty similar. Has a large featured banner, and basically rows of movies or tv shows with every few rows having a featured section.
3. Apple 🎯
https://www.apple.com/
You'll know what I mean by "big block" design. Apple does this well. It's clean, intuitive and pretty straight forward. If you break everything down into smaller components, you'll see how easy it would be to implement the design.
4. Airbnb🎯
https://www.airbnb.co.in/?locale=en&_set_bev_on_new_domain=1638253270_ZWVmZDNiNGY3OWJh
Airbnb is such a beautiful website! The assets are amazing. Break this design down into smaller components, and you'll see how it's just a bunch of big rows and small rows. Blocks either spanning multiple columns, or the entire row.
5.SpaceX🎯
https://www.spacex.com/
Super easy design. SpaceX is basically multiple fullscreen images with fade up content and a link section.
6. NVIDIA🎯
https://www.nvidia.com/en-us/
Another easy, but professional looking design. Just a banner, grid layout and rows.
7.Razer🎯
https://www.razer.com/
A mix of a large home banner, full page featured sections, and big box design. Have fun with this sick color scheme!
8.Salesforce🎯

Detailed RoadMap to become Web3.0 devloper
0️⃣ Prerequisites
You should know JavaScript and web development in general.
If you don't, you should take a step back at this point and learn about web development first.
There are so many awesome courses and tutorials out there. You won't have a hard time finding good ones.
1️⃣ Learn The Basics Of Blockchain
You need to know what you work with. Blockchains are an incredible piece of technology, but they also aren't trivial to learn.
You'll have to put some time into it to understand what you will later build on.
A good idea is to start here. 👇🏻
https://www.udemy.com/course/blockchain-theory-101/
And then advance a little further with this. 👇🏻
https://www.edx.org/course/blockchain-technology
When you went through this, you have a general idea about blockchain technology. This is a great foundation for your further learning.
2️⃣ Learn About Smart Contracts
Smart contracts are how you can actually program the blockchain. They are code deployed to the chain, written in some language that blockchain nodes can execute.
Smart contracts can nearly do everything, from fungible and non-fungible tokens to the backend of your next decentralized app. They are, however, different from the code you usually write.
They'll make up a good portion of your future work, so better understand them well.
A good introduction that also introduces you to Solidity can be found here. 👇🏻
https://www.coursera.org/learn/smarter-contracts
3️⃣ Learn How To Interface With The Blockchain
Decentralized apps consist of two components: Your frontend and smart contracts executed on the blockchain.
For your frontend to talk to the blockchain, you'll need to interface with it.
This is where libraries come in.
There are two popular choices to interface with blockchains that implement the Ethereum API:
🔹 ethers.js
🔹 Web3.js
Pick one, and learn it well. You will definitely need it. It's one of your most important tools from now on.
4️⃣ Learn Solidity
There are many blockchains out there, and nearly equally as many of them come with their own unique way of building smart contracts.
Solidity, however, is the language of the Ethereum VM which is integrated into many other blockchains.
Solidity won't only serve you well on Ethereum. It will also help you to build smart contracts on other chains.
The job market for Solidity developers is the largest by far. Many businesses build or want to build on Ethereum.
It could take a long time until another blockchain reaches the same level of adoption that Ethereum has reached.
Although it currently has a few problems (the chain is overloaded), the community is actively working on migrating the consensus over to Proof-of-Stake.
All scaling problems will be gone when this happens, and the adoption rate might sky-rocket even further.
Until then, layer-2 solutions help to scale the chain, so you don't need to worry about your job and choice.
What you especially need to understand is how gas works and how each line of code you write in Solidity affects the price of execution of your smart contract.
There is no way around it. Unfortunately, some companies optimize aggressively for gas consumption.
If you want to work in this field, you'll need to learn to optimize your code. It will be part of your job and a huge part of some interviews because thorough optimization can save millions of dollars each year for a heavily used app or contract.
Curious? Crypto Zombies is an awesome start to Solidity. You learn by basically playing a game. What's better than this?

5️⃣ Build Your Portfolio
A portfolio of projects can help immensely in your job search. If you want to work in this field, build, build, build.
To give you a rough idea of what a project should contain:

A good introduction that also introduces you to Solidity can be found here. 👇🏻

3️⃣ Learn How To Interface With The Blockchain
Decentralized apps consist of two components: Your frontend and smart contracts executed on the blockchain.
For your frontend to talk to the blockchain, you'll need to interface with it.
This is where libraries come in.
There are two popular choices to interface with blockchains that implement the Ethereum API:
🔹 ethers.js
🔹 Web3.js
Pick one, and learn it well. You will definitely need it. It's one of your most important tools from now on.
4️⃣ Learn Solidity
There are many blockchains out there, and nearly equally as many of them come with their own unique way of building smart contracts.
Solidity, however, is the language of the Ethereum VM which is integrated into many other blockchains.
Solidity won't only serve you well on Ethereum. It will also help you to build smart contracts on other chains.
The job market for Solidity developers is the largest by far. Many businesses build or want to build on Ethereum.
It could take a long time until another blockchain reaches the same level of adoption that Ethereum has reached.
Although it currently has a few problems (the chain is overloaded), the community is actively working on migrating the consensus over to Proof-of-Stake.
All scaling problems will be gone when this happens, and the adoption rate might sky-rocket even further.
Until then, layer-2 solutions help to scale the chain, so you don't need to worry about your job and choice.
What you especially need to understand is how gas works and how each line of code you write in Solidity affects the price of execution of your smart contract.
There is no way around it. Unfortunately, some companies optimize aggressively for gas consumption.
If you want to work in this field, you'll need to learn to optimize your code. It will be part of your job and a huge part of some interviews because thorough optimization can save millions of dollars each year for a heavily used app or contract.
Curious? Crypto Zombies is an awesome start to Solidity. You learn by basically playing a game. What's better than this?
