I want to be developer i am learning according to the curriculum.How can i confirm that i had become a decent developer?Will i get some type of certificates.
create a portfolio that showcase what you have done. The projects in the curriculum also include a portfolio, that could be a start, but you will need to ass to it more advanced projects.
once you have completed all the projects for a certain certification you can claim the certificate in the settings, after agreeing to the Academic Honesty Pledge
