🎯 Overview

SmartSales AI is an autonomous AI agent that revolutionizes retail personalization by combining:

• Machine Learning - Collaborative filtering for product recommendations
• AWS Bedrock Reasoning - Autonomous SQL generation and natural language understanding
• Real-Time Analytics - DuckDB for lightning-fast queries
• Customer Intelligence - RFM segmentation for targeted marketing

The Agent's Autonomous Workflow

User Question → "Show me top 5 customers by revenue"
     │
     ▼
[Agent: Do I need SQL for this?] → YES
     │
     ▼
[Agent: Generates SQL Query] → SELECT CustomerID, SUM(UnitPrice * Quantity)...
     │
     ▼
[DuckDB: Executes Query] → Returns DataFrame
     │
     ▼
[Agent: Interprets Results] → "Here are your top 5 revenue-generating customers..."
     │
     ▼
User sees: Summary + SQL + Data + Natural Language Explanation

Why This Matters

Traditional recommendation systems are:

• ❌ Impersonal (just product IDs and scores)
• ❌ Not scalable (manual personalization limited to 100s of customers)
• ❌ Expensive (human-written messages cost $0.50 each)

SmartSales AI delivers:

• ✅ Personal, contextual messages (AI-generated in natural language)
• ✅ Massively scalable (10,000+ customers in seconds)
• ✅ Cost-effective ($0.01 per AI message = 98% savings)

🛠️ Technical Implementation

How the AI Agent Works

1. Intent Analysis

def process_chat_message(user_input: str):
    # Agent decides: Do I need SQL?
    sql_check_prompt = f"Does '{user_input}' require database query?"
    needs_sql = bedrock_client.invoke_model(...)
    
    if needs_sql == "YES":
        generate_and_execute_sql()
    else:
        provide_general_answer()

2. SQL Code Generation

def generate_sql(user_query: str, schema: str):
    prompt = f"""
    Table: sales_data
    Schema: {schema}
    Question: {user_query}
    
    Generate executable DuckDB SQL query.
    """
    
    sql = bedrock_client.invoke_model(prompt)
    return clean_sql(sql)  # Remove markdown, validate

3. Autonomous Execution

def execute_query(sql: str):
    # Agent runs its own generated code
    results = duckdb_conn.execute(sql).fetchdf()
    
    # Agent interprets results
    interpretation = bedrock_client.invoke_model(
        f"Explain these results: {results}"
    )
    
    return results, interpretation

4. Personalized Messaging

def generate_message(customer_id, history, recommendations):
    prompt = f"""
    Customer {customer_id} purchased: {history}
    Recommended: {recommendations}
    
    Write a warm, personalized 3-4 sentence message.
    Be conversational, not robotic.
    """
    
    return bedrock_client.invoke_model(prompt)

Collaborative Filtering Algorithm

# Build user-item matrix
user_item_matrix = df.pivot(
    index='CustomerID',
    columns='ProductID', 
    values='Quantity'
).fillna(0)

# Calculate user similarity (cosine)
user_similarity = cosine_similarity(user_item_matrix)

# Generate predictions
scores = user_similarity[target_user] @ user_item_matrix

# Exclude already purchased, rank by score
recommendations = scores[not_purchased].argsort()[::-1][:N]

RFM Segmentation Logic

# Calculate RFM metrics
rfm = df.groupby('CustomerID').agg({
    'InvoiceDate': lambda x: (NOW - x.max()).days,  # Recency
    'InvoiceNo': 'count',                           # Frequency
    'TotalPrice': 'sum'                             # Monetary
})

# Score on 1-5 scale
rfm['R_Score'] = pd.qcut(rfm['Recency'], 5, labels=[5,4,3,2,1])
rfm['F_Score'] = pd.qcut(rfm['Frequency'], 5, labels=[1,2,3,4,5])
rfm['M_Score'] = pd.qcut(rfm['Monetary'], 5, labels=[1,2,3,4,5])

# Segment based on scores
if R>=4 and F>=4 and M>=4: segment = 'Champions'
elif R<=2 and F<=2: segment = 'Lost'
# ... more rules

🐛 Troubleshooting

Common Issues

AWS credentials not found

# Verify credentials file exists
cat ~/.aws/credentials  # Linux/Mac
type C:\Users\USERNAME\.aws\credentials  # Windows

# Check permissions (Linux/Mac)
chmod 600 ~/.aws/credentials

Bedrock model access denied

Solution: AWS Console > Bedrock > Model access > Request access
Wait for approval (usually instant for openai.gpt-oss-20b-1:0)

SQL generation errors

Solution: Rephrase your question more specifically
Example: "top customers" → "top 10 customers by revenue"

Memory errors with large datasets

Solution: Filter data by date before upload
Example: Last 12 months only, or top 10K customers

🔐 Security Best Practices

AWS Credentials:

• ✅ Never commit credentials to git
• ✅ Use .gitignore to protect .aws/ directory
• ✅ Set file permissions: chmod 600 credentials
• ✅ Rotate keys every 90 days
• ✅ Use minimal IAM permissions: bedrock:InvokeModel only

Data Privacy:

• ✅ Customer data (CSV files) is gitignored by default
• ✅ Database files (DuckDB) are gitignored
• ✅ Review data before sharing screenshots
