Create User Profile Schema

[meshackyaro]

Description

This issue aims to address the implementation of Create User Profile Schema.

The core objective is to: Design the DB entity for freelancers and clients (wallet address, name, bio, rating).

By completing this feature, we will ensure that the TrustFlow protocol maintains its high standards for security, usability, and decentralized logic. This issue requires careful attention to the Backend architecture and adherence to the existing project conventions.

When picking up this issue, please ensure you document any new dependencies or architectural decisions made during development.

Hi TrustFlow Team,

I would love to take on Issue #28: "Create User Profile Schema" for trustflow-core. Having a clean, strictly typed, and extensible schema for user and agent profiles is critical for a reputation protocol to ensure seamless data propagation and accurate vector tracking.

My Understanding of the Task

The goal is to design and implement a structured data model (schema) representing a user/agent profile within trustflow-core. Based on the protocol's architecture, this schema should efficiently capture:

1. Core Identity: Unique identifiers (DIDs or Stellar public keys) to map reputation flows accurately.
2. Metadata: Basic user/agent information (e.g., handle, display name, profile description, creation timestamp).
3. Reputation Anchor Points: Structure to hold or link to multi-dimensional reputation scores or vector states if needed by the core loop.
4. Validation Layers: Robust data validation to prevent corrupt or malicious profiles from breaking the interaction graph.

Technical Approach

• Schema Framework: I propose defining this using [TypeScript interfaces / Zod / JSON Schema / Prisma — Choose the one matching the tech stack if known, e.g., TypeScript/Zod is standard] to ensure strict compile-time or runtime type safety.
• Validation: Implement clean parsing logic to fail early if incoming profile updates lack mandatory cryptographic references or are formatted incorrectly.
• Modularity: Ensure the schema supports extension fields (e.g., custom topic embeddings or future protocol-level attributes) without introducing breaking changes.
• Documentation & Tests: Add robust unit tests covering valid, invalid, and edge-case inputs, along with explicit code documentation.

Why I'm a Good Fit

• I am proficient in TypeScript and data modeling best practices.
• I have experience dealing with open-source repositories and building schemas that interface cleanly with decentralized technologies/networks like Stellar.
• [Optional: Add a brief sentence about any specific experience you have with schemas, validation libraries like Zod/Yup, or backend architectures].

Proposed Timeline

• Day 1: Review current protocol context, map out necessary fields with the maintainers, and draft the schema structure.
• Day 2-3: Write the schemas, introduce runtime validation rules, and add comprehensive unit tests.
• Day 4: Submit a clean PR, verify CI passes, and address any feedback promptly.

I am ready to get started immediately. Let me know if there are existing design guidelines or specific field lists you want prioritized for this initial version!

Best regards,
