Serverless Lead Capture System

A modern, fully serverless contact form solution built on AWS that captures leads, stores them securely, and sends instant email notifications — without managing any servers.

✨ Features

• Beautiful, animated, responsive contact form (Tailwind CSS + vanilla JS)
• Fully serverless architecture (pay-per-use)
• Real-time data storage in DynamoDB
• Professional HTML email notifications via SES
• Secure with least privilege IAM roles
• CORS enabled and production-ready
• CDN ready (CloudFront)

🏗️ Architecture

• Frontend: Static HTML + Tailwind hosted on S3 + CloudFront
• Backend: API Gateway + AWS Lambda (Python)
• Database: Amazon DynamoDB
• Notification: Amazon SES
• Security: IAM Roles with least privilege

🚀 How It Works

1. User submits the contact form
2. Request hits API Gateway → Triggers Lambda
3. Lambda validates data → Stores in DynamoDB
4. Sends professional email notification via SES
5. Returns success response with smooth UI feedback
