📦 5. Maintain Server Infrastructure
You configure cloud instances, containerize apps with Docker, and deploy via AWS, Azure, or Heroku.

🧪 6. Test and Debug Code
You write unit tests, debug API errors, and fix backend bugs to keep systems running smoothly.

📈 7. Optimize Performance
You monitor logs, reduce response times, and handle concurrency, caching, and load balancing.

🔄 8. Integrate with Third-Party Services
You connect payment gateways, email services, analytics tools, and more via APIs and SDKs.

🔧 9. Automate Processes
You write scripts or cron jobs to handle background tasks like data backups, cleanup, or notifications.
