✅ Definition of Done (DoD):

1. Refactor scss to scss modules as following:

• remove all parent selector & .card-content -> .card-content.
• change all possible values to variables if such exists.
• rename all classes to be generic e.g .nodejs-trainer 🙅‍♂️ -> .trainer 👌.
• and everything in your opinion that needs to be refactored

3. delete AlumniProps type
4. in the constants.ts remove type annotation from alumni and change it as following

const alumni = [...] as const

5. move unit test inside the ui folder
6. move all the magic numbers in the constants and place these constants inside the constants.ts folder
