Build projects or learn Uniswap v4 ??

Heyy Guys, im back from learning foundry and next looking to build some projects and host them in the testnet.

I was thinking of building a standard and solid project (like DAO/DEX) instead of small projects..

So when i looked up, i came to know that uniswap is very useful in developing commercial level projects and has many built-in features ideal for production grade apps..

Now should i learn Uniswap and then build a solid project or just build a project and then learn Uniswap..

Thanks in advance...
