Pagebuilder is my favourite project! It can build landing pages with ready to use page`s components like headers, footers e.t.c. You can try it before registration - I didn`t make special validation. For example, you can register using "123" like password. Anyway, you will create real pagebuilder account.
This project was code with PERN-stack (PostgreSQL, Express, React, Node.js).
I used react and redux for the front-end. Then front-end was deployed on vercel. Also, I tried Back-end experience for the first time: I have acquired basic knowledge of how to work with node.js (express), postgreSQL, jwt-token for auth. Node.js (express) app and database of the project was deployed on Heroku.
