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

In the realm of software engineering, adopting best practices and agile methodologies is essential for streamlining development processes and ensuring the delivery of top-notch software products. One of the foundational principles in this domain is Continuous Integration and Continuous Deployment (CI/CD), which automates the integration of code changes and their deployment to production environments. By regularly testing and deploying changes, CI/CD minimizes integration issues and accelerates the delivery pipeline. Test-Driven Development (TDD) is another key practice where developers write automated tests before writing actual code, ensuring that the code meets requirements and remains functional even after subsequent modifications.
Code reviews play a vital role in maintaining code quality and knowledge sharing within teams. Through regular peer reviews, developers can identify issues, adhere to coding standards, and enhance overall code quality. Version control systems like Git are indispensable tools for managing code changes, tracking history, and facilitating collaboration among team members. Embracing Agile principles, such as customer collaboration and delivering working software, is crucial for adapting to changing requirements and delivering incremental value to customers. Agile methodologies like Scrum, Kanban, and Extreme Programming provide frameworks for organizing work, fostering collaboration, and ensuring adaptability in software development projects. By implementing these best practices and agile methodologies, software engineering teams can enhance productivity, collaboration, and the overall quality of software delivered to customers.

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)
