🧠 Synthetic Data Generator

A Python-based tool to generate structured, synthetic job postings using open-source LLMs from Hugging Face.
This project supports both script-based execution and an interactive Colab notebook, making it ideal for rapid prototyping, dataset bootstrapping, or demonstrating prompt engineering techniques.

This tool helps:

• Researchers create labeled training data for NLP classification or QA
• HR tech startups prototype recommendation models
• AI instructors demonstrate few-shot prompting in class

---

✨ Features

• 🔗 Integrates Hugging Face Transformer models
• 📄 Generates realistic job postings in structured JSON format
• 🧪 Supports prompt engineering with control over output length and variability
• 🧠 Minimal Gradio UI for non-technical users
• 📓 Jupyter/Colab support for experimentation and reproducibility
