Todo list app is the classic simple project to test a new framework and how it works. It can be frontend only, or full stack, with a classic DB or a serverless architecture, has a simple CRUD flow that covers all your basic operations, can be easily expanded to have multiple users or advanced features, or scaled down to just a single local or global list, and isn't too difficult to design or style. It's like the most simple "full" project you can do. More on reddit.com

Recreate a service you see on the internet like notion or Google calendar, best way to level up your full-stack game imo More on reddit.com

Event driven microservices based e-commerce system Use a nosql db since you already have experience with Postgres Use events for all communication between services. Services can include things like Orders, Cart, invoices, products, stock, and so on Focus on the problem that arise form this sort of design. Dealing with eventual consistency and errors are 2 big issues. For instance imagine you place an order. You might need the order service to publish a message to tell the stock service to reduce stock, to tell an email service to email the user, to tell the cart service to empty the users cart, the payment service to charge the user and so on, but then if the payment service (or something else) fails you need to roll back all the other services to bring the system back to a consistent state. What if one of the services fails during the rollback? What if the stock service fails to reduce stock and another user orders something that doesn’t exist in the warehouse? And so on Chaos engineering is your friend. Randomly take down services in the middle of transactions, introduce massive artificial network delays, emulate back pressure on the event bus. If your system can service a thorough chaos monkey test and end up in a consistent state then you will have done a good job More on reddit.com

I’ve been doing web dev for a while :) All of them are fine, but Odin is my recommendation, don’t rely too much on videos. Don’t overthink it. I learned programming from an old $8 used book. The rest from online docs. Anything will teach you if you stick with it and practice. Don’t fall into the trap of trying to find the perfect resource. More on reddit.com
