Code Whisperer Time Machine

Project: "Code Whisperer Time Machine"
Transform legacy codebases into modern, AI-interactive, self-documenting systems

Problem Statement
Developers often struggle with understanding how and why code evolved over time, especially in large or legacy codebases. Tracking changes, understanding intent, and maintaining documentation is inefficient and time-consuming.

🧠 Concept:
Build a tool that takes a real legacy codebase (e.g., COBOL, Perl, or early Java) and uses Amazon Q Developer to:

Translate it into modern languages (e.g., TypeScript, Python or Go)

Use Amazon Q as an AI co-pilot to explain functions, suggest rewrites, and turn old spaghetti code into clean microservices or serverless functions.

Solution Overview
Code Whisperer Time Machine is an intelligent tool that brings version control history to life. It enables developers to explore, visualize, and understand the evolution of their code with AI-powered insights.

Key Features & Functionality
🕰 Time Machine UI: Scrollable, interactive commit timeline

💡 AI Commit Whispering: Summarizes the intent behind changes

👁️ Visual Diff Engine: Highlights changes at file, function and logic levels

🔍 Smart Search: Search history by feature, keyword or behavior

🔄 Auto-Documentation: Generates markdown changelogs or inline comments

🧪 Demo Flow:
User uploads old codebase (e.g., COBOL or PHP app)

System analyzes it with Q Developer

UI shows:

Suggested modernized architecture (e.g., serverless + event-driven)

User can approve code transformations step-by-step

Outputs:

Transformed TypeScript/Python code

CDK infrastructure-as-code

💡 Why it's a great fit:
Feels "impossible" — AI-powered reverse engineering + full-stack transformation

Explores deep capabilities of Amazon Q (understanding + generation)

Useful for real-world modernization efforts (e.g., governments, banks)

Visually impressive and interactive — perfect for demos

✅ Quick Starter Example (Node.js → Python):
You can prompt Q Developer with:

# Use Q Developer to translate this Node.js function:
function calculateTax(income) {
    if (income < 10000) return 0;
    return income * 0.2;
}

calculate_tax = lambda income: 0 if income < 10000 else income * 0.2

// File: package.json
    setTimeout(() => mermaid.init(undefined, ".mermaid"), 0);
  };

  return (
    <div className="p-6 font-mono">
      <h1 className="text-2xl mb-4">🕰️ Code Whisperer Time Machine</h1>
      <textarea
        rows={8}
        className="w-full p-2 border"
        value={legacyCode}
        onChange={(e) => setLegacyCode(e.target.value)}
      />
      <button className="mt-2 p-2 bg-blue-600 text-white rounded" onClick={handleAnalyze}>
        Analyze & Translate
      </button>

      {explanation && (
        <div className="mt-4">
          <h2 className="font-bold">Explanation:</h2>
          <p>{explanation}</p>
        </div>
      )}

      {translated && (
        <div className="mt-4">
          <h2 className="font-bold">Translated Python Code:</h2>
          <pre className="bg-gray-100 p-2">{translated}</pre>
        </div>
      )}

      <div className="mt-4">
        <h2 className="font-bold">Architecture Diagram:</h2>
        <div className="mermaid">{diagram}</div>
      </div>
    </div>
  );
};

export default App;

I've scaffolded a working project called "Code Whisperer Time Machine" that simulates legacy code translation and visualization using React, TypeScript and Mermaid.js.

✅ To run the demo:

npm install
npm run dev

Then open your browser at http://localhost:5173 to use the app.

⚙️** Tech Stack:**
Amazon Q Developer (code translation, refactoring, understanding)

AWS CDK + Lambda / Step Functions (to modernize functionality)

React + TypeScript front-end (to visualize the AI-guided transformation)

Frontend: React, Tailwind CSS, D3.js (for timeline visualization)

Backend: Node.js / Python (Flask or FastAPI)

AI Layer: OpenAI GPT (for commit summaries)

Deployment: Docker, Vercel / Heroku
