Docker & Singularity Expert Needed for App Containerization

I need a skilled professional with extensive experience in Docker Containers and Singularity to help containerize some applications. These applications will primarily run on a Linux operating system.

Key points:
- The apps don't rely on specific dependencies or libraries, they utilize standard ones.
- The type of apps to be containerized hasn't been specified yet.

Ideal candidates should have:
- Proficiency in Docker and Singularity
- Experience with Linux operating systems
- Ability to work with standard libraries and dependencies
- Skills in identifying and solving potential containerization issues.

Please respond with details about your experience - saying "I can do it" is not enough.
