Server Cleanup & Optimization on DigitalOcean

My DigitalOcean droplet is completely full. I need a professional to help me free up some space. Most of the space is being taken up by my code base.

Key tasks:
- Assess the current server storage situation.
- Identify and delete old or unused files.
- Suggest and implement best practices for server optimization.
- Recommend a suitable code repository for future use.

Ideal candidates should have:
- Extensive experience with DigitalOcean.
- Strong knowledge in server management and optimization.
- Proficiency in identifying unnecessary files.
- Previous experience with code bases and implementing code repositories.
- Excellent communication skills for explaining technical details in a simple manner.
