Pixelated Empathy Architecture

​
System Overview

Pixelated Empathy is built on a modern, secure, and scalable architecture that combines the best practices from various platforms while maintaining strong privacy and security measures through Zero-Knowledge Encryption and HIPAA compliance.

​
Core Components

​
Frontend Architecture

  • UI Layer
  • Data Flow
The UI layer is built using React and Next.js, incorporating design elements from Liftoff’s interview platform:
  • Component Structure
    • Atomic Design Principles
    • Shared Component Library
    • Theme Provider (Dark/Light modes)
    • Responsive Layout System
  • State Management
    • React Context for global state
    • React Query for server state
    • Local storage for persistence
    • Secure credential handling

​
Backend Architecture

​
Database Design

​
Supabase Schema

-- Core Tables
CREATE TABLE users (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
email TEXT UNIQUE NOT NULL,
encrypted_data JSONB,
settings JSONB DEFAULT '{}'::jsonb,
created_at TIMESTAMPTZ DEFAULT NOW(),
updated_at TIMESTAMPTZ DEFAULT NOW()
);

CREATE TABLE sessions (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
user_id UUID REFERENCES users(id),
metadata JSONB,
started_at TIMESTAMPTZ DEFAULT NOW(),
ended_at TIMESTAMPTZ
);

CREATE TABLE messages (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
session_id UUID REFERENCES sessions(id),
encrypted_content TEXT NOT NULL,
metadata JSONB,
created_at TIMESTAMPTZ DEFAULT NOW()
);
