I am Brazilian, I would like some guidance on how to start a salesforce developer career. I am sorry for my english. Can someone help me ?
Here's a great article from Salesforce Ben that talks about becoming an SF Developer: https://www.salesforceben.com/8-steps-to-become-a-salesforce-developer/
It's a little light on info, but for a beginner who just wants to know how to become a dev, this is a good intro.
The main thing you want to focus on is being a good admin and understanding basic and advanced admin functions before moving into developing applications. Some may disagree with this, if they have prior programming experience.
The following are the topics I could find from the trailhead. You could go from simple topics like soql/sosl from the trailhead and then move up the difficulty level so that it would be easy to understand.
- Salesforce Platform
- SOQL / SOSL
- VisualForce Pages
- Lightning Components
- Lightning Web Components
- System integration
- Web services
