+	## 🏗️ System Architecture
+
+	OptiQA follows a modular microservice-inspired structure:
+
+	1. Frontend (React.js)
+	Handles user interaction, authentication, prompt submission, and data visualization.
+
+	2. Backend (Node.js + Express)
+	Manages user requests, invokes GPT-4o-mini for AI processing, executes Playwright tests, and interacts with PostgreSQL.
+
+	3. AI Layer (OpenAI GPT-4o-mini)
+	Generates test scripts based on natural language prompts.
+
+	4. Database Layer (PostgreSQL)
+	Stores users, prompts, test results, execution logs, and screenshots.
+
+	5. Playwright Test Engine
+	Executes generated test scripts and sends results back to the backend for storage and visualization.
