## 🚀 Project Overview

**MachineInnovators Inc.** focuses on scalable, production-ready machine learning applications. This project is a comprehensive **MLOps solution** designed to monitor online company reputation through automated sentiment analysis.

Unlike standard data science experiments, this repository demonstrates a **full-cycle ML workflow**, moving from model training to automated deployment. It addresses the business need for real-time reputation tracking by classifying social media feedback (Positive, Neutral, Negative) using an automated pipeline.

### Key Features
* **Production-First Approach:** Focus on scalability, modularity, and code quality.
* **CI/CD Automation:** Integrated pipeline for automated testing and deployment using GitHub Actions.
* **Continuous Deployment:** Automatic deployment to Hugging Face Spaces upon successful builds.
* **Reproducibility:** Code and environment are strictly versioned to ensure consistent results.

## ⚙️ Architecture & MLOps Workflow

The project follows a rigorous MLOps pipeline to ensure reliability and speed of delivery:

1.  **Data Ingestion & Preprocessing:**
    * Cleaning and tokenization of social media data using industry-standard libraries.
    * Usage of public datasets labeled for sentiment analysis.

2.  **Model Development:**
    * Implementation of a robust sentiment classification model.
    * Optimization for inference speed and accuracy.

3.  **CI/CD Pipeline (GitHub Actions):**
    * **Linting:** Enforces code style (PEP8) to maintain high readability.
    * **Testing:** Unit tests ensure that data processing and prediction logic function correctly before any merge.
    * **Delivery:** Upon passing all checks on the `main` branch, the application is packaged and deployed.

4.  **Deployment:**
    * The model is served via a web interface hosted on **Hugging Face Spaces**, allowing for immediate user interaction and testing.
