## What is it?
HyperTrack is a gym workout tracker built on AWS infrastructure. It's designed to learn cloud architecture patterns while building something actually useful.
## Why I built it
I wanted hands-on experience with AWS beyond just tutorials. Building a real application with authentication, databases, and APIs taught me more than any certification course could.
## Architecture
- API Gateway for RESTful endpoints
- Lambda functions for serverless compute
- DynamoDB for workout data storage
- Cognito for user authentication
- S3 for static asset hosting
## Challenges
- IAM permissions — getting the right balance of security and functionality
- Cold start latency with Lambda
- DynamoDB data modeling for efficient queries
- CORS configuration headaches
## What I learned
- Serverless architecture patterns
- Infrastructure as Code with CloudFormation
- NoSQL data modeling
- API design and authentication flows
- Cost optimization in the cloud
