The Future of Data Engineering is Autonomous

Quick Start • Features • Architecture • Demo • Docs • Community

🎯 What if your data pipeline could think for itself?

Agentic Data Engineering Platform is an open-source, production-ready ETL solution that combines the Medallion Architecture with AI-powered agents that autonomously profile, clean, and optimize your data—so you can focus on insights, not infrastructure.

✨ Why Choose This Platform?

🤖 AI-Powered Intelligence

Three autonomous agents work 24/7:

Profiler Agent: Auto-discovers data issues
Quality Agent: Continuously monitors health
Remediation Agent: Self-heals data problems

No more manual data cleaning!

⚡ Blazing Fast Performance

Built on modern tech that's 10x faster:

Polars for DataFrame operations
DuckDB for analytical queries
Prefect for reliable orchestration

Process millions of rows in seconds!

🏗️ Enterprise Architecture

Industry-standard Medallion pattern:

🥉 Bronze: Raw, immutable data
🥈 Silver: Cleaned, validated data
🥇 Gold: Business-ready aggregates

Scale from prototype to production!

📊 Beautiful Dashboards

Interactive Streamlit interface:

Real-time quality metrics
Visual data lineage
Performance monitoring
One-click insights

From data to decisions in minutes!

🎬 See It In Action

# 60 seconds to your first pipeline!
git clone <your-repo> && cd agentic-data-engineer
python -m venv venv && source venv/bin/activate
pip install -r requirements.txt
python scripts/generate_sample_data.py
python src/orchestration/prefect_flows.py
streamlit run dashboards/streamlit_medallion_app.py

🎉 Boom! Your autonomous data pipeline is running!

🚀 Quick Start

Prerequisites

✅ Python 3.10 or higher
✅ 4GB RAM (minimum)
✅ 1GB free disk space
✅ Love for clean data 💙

Installation

Step 1: Clone & Setup Environment

```bash # Clone the repository git clone https://github.com/yourusername/agentic-data-engineer.git cd agentic-data-engineer

Create virtual environment

python -m venv venv

Activate it

source venv/bin/activate # On Windows: venv\Scripts\activate

Install dependencies

pip install -r requirements.txt

</details>

<details>
<summary><b>Step 2: Initialize Project</b></summary>
```bash
# Run automated setup
python scripts/setup_initial.py

# Generate sample e-commerce data (1000 records with quality issues)
python scripts/generate_sample_data.py

✅ Output: Sample dataset with intentional issues for testing AI agents

Step 3: Run Your First Pipeline

```bash # Execute the complete ETL pipeline python src/orchestration/prefect_flows.py ```

🎯 Watch as the agents:

✅ Profile your data (discover issues)
✅ Score data quality (0-100)
✅ Auto-remediate problems (fix issues)
✅ Create Bronze → Silver → Gold layers
✅ Generate business aggregates

🚀 Starting Agentic ETL Pipeline
✅ Extracted 1,000 rows
🔍 Profiling dataset: Found 10 issues
📊 Quality Score: 92/100
🔧 Auto-remediation: 7 actions taken
✅ Pipeline completed successfully!

Step 4: Launch Dashboard

```bash streamlit run dashboards/streamlit_medallion_app.py ```

💎 Features That Make Us Different

🤖 Autonomous Data Quality

# Traditional Approach: Manual, Error-Prone
df = pd.read_csv("data.csv")
df = df.dropna()  # Hope for the best?
df = df.drop_duplicates()  # Good enough?
# ... 50 more lines of cleaning code ...

# Agentic Approach: AI-Powered, Automatic
from src.agents.agentic_agents import DataProfilerAgent, RemediationAgent

profiler = DataProfilerAgent()
profile = profiler.profile_dataset(df, "my_data")
# 🔍 Discovers: 23 issues across 8 categories

remediation = RemediationAgent()
df_clean, actions = remediation.auto_remediate(df, profile['issues_detected'])
# 🔧 Fixed: Whitespace, duplicates, negatives, outliers, formats
# ✅ Result: 98% quality score (up from 73%)
