You would need to state your first and last name. We do this because this project is specifically for portfolio and educational purposes. Anyone who gives out their full name for the project means they will receive a proper credit and may use their work from the project for job and school portfolios/resumes.
If it is a matter where your parents do not want you to give out personal information, then I’m afraid we can’t give you a proper credit. Nicknames do not count.
