Debugging AWS Java/Scala Application -- 2

As the project owner, I need an expert to fix bugs found in my existing software application which uses Scala, Java, and AWS. The main issues encountered are:

- Problems during data processing
- Issues in the user interface
- Inefficiencies during interactions with AWS services

The specific performance challenges include slow data retrieval, high memory usage, and long processing times in the data processing aspect.

Ideal skills and experiences include:

- Proficiency in Scala and Java
- Proven experience working with AWS services
- Strong debugging skills
- Track record in performance optimization.

Looking forward to swift and efficient solutions.
