Tell us about your participation and roles in the projects you have implemented.

In one of the projects, I participated as a Python script developer for data processing automation. My tasks included writing modules for data parsing and cleaning, as well as integrating with a database.

In another project, I served as a team lead for a small team, responsible for the application's architecture on Django, task distribution, and code review. I also worked on performance optimization and writing unit tests.

Overall, my roles ranged from developer to team coordinator, which allowed me to gain experience both in technical implementation and process management.
