# Senior Backend
Complete toolkit for senior backend with modern tools and best practices.
## Quick Start
### Main Capabilities
This skill provides three core capabilities through automated scripts:
```bash
# Script 1: Api Scaffolder
python scripts/api_scaffolder.py [options]
# Script 2: Database Migration Tool
python scripts/database_migration_tool.py [options]
# Script 3: Api Load Tester
python scripts/api_load_tester.py [options]
```
