Build Enterprise-Grade User Profile, Identity, Reputation & Portfolio System

Build a world-class profile system inspired by:

• [LinkedIn](https://www.linkedin.com?utm_source=chatgpt.com)
• [GitHub](https://github.com?utm_source=chatgpt.com)
• [Devfolio](https://devfolio.co?utm_source=chatgpt.com)
• [Unstop](https://unstop.com?utm_source=chatgpt.com)

The profile system becomes the user's digital identity across the platform.

It should be powerful enough for:

Students
Developers
Designers
Founders
Mentors
Judges
Recruiters
Organizations

Every action on the platform should contribute to the user's profile and reputation.
