I see two things for noticeable differences between senior and junior developers:
1) edge case testing - (don't make the code work for that one case and stop)
2) code is written in a way it can be modified by itself as its own piece and not interfere with the entire program. (Technical concepts tight coupling vs loose coupling)

Hey Tony, I highly recommend you consider undergoing training in any Agile courses. This will be your first step towards mastering the language of Agile Methodology.
After you've completed the training, try to find answers to these questions:
- What roles exist in Agile Methodology and who is responsible for what?
- What are the working methods?
- What tools are available for your Agile journey and how can they be utilized?
- What estimation methods are used to justify tasks, jobs, or user stories?
- What defines 'Done'? What is the success criteria?
- Which projects are suitable for Agile methodology and which ones aren't?
- In a given environment, what is the scope for implementing Agile Methodology? What does the future hold?
- How is success measured in Agile methodology?
- What types of metrics or KPIs are measured in Agile methodology?
- What is a User Journey? What are Epics and Features?
- What is a Value Stream?
- What is Scrum?
Once you've found clarity in these areas, you'll find it much easier to analyze your question about the difference between a junior and senior level software engineer.
In my view, everyone brings something unique to the journey. However, before forming a team, everyone is trained in Agile and, if necessary, in certain skills as well.
You'll be able to choose your user story based on your strengths and contribute to the journey.
I hope this guidance is helpful.
If you need further clarification, I'm more than happy to have a one-on-one discussion.
Best Regards,
Chiranjib
