Implement user module service layer

[MRIARC-08]

User operations need a complete service layer:

Repository (src/modules/user/user.repository.ts):

• Get user profile
• Update user profile
• Get user stats
• Update user preferences

Service (src/modules/user/user.service.ts):

• Profile retrieval and updates
• Stats calculation and caching
• Preference management
• User onboarding flow

Controller (src/modules/user/user.controller.ts):

• GET /api/user/getUser
• PUT /api/user/updateUser
• GET /api/user/stats
• PUT /api/user/preferences

Types (src/modules/user/user.types.ts):

• UserProfile DTO
• UserStats DTO
• UserPreferences DTO

Expected outcome: Complete user management API.

This is a GSSoC'26 contribution opportunity!

Hey! I would like to implement the user module service layer. Approach: 1) Create user service with CRUD operations 2) Add profile management functions 3) Add avatar upload/handling 4) Write service-level unit tests. Assign me under GSSoC?

Hi @MRIARC-08, I would like to work on this issue .

I can implement the complete user module service layer by:

Creating repository functions for profile, stats, and preferences management
Building service-layer logic with proper validation and business handling
Implementing controller endpoints for user operations
Defining clean DTO/types for maintainability
Adding error handling and reusable response structures
Writing basic unit tests for the service layer if required

I have experience working with TypeScript/Node.js backend architecture and would love to contribute to this feature.

Could you please assign this issue to me?
