NodeJS to Java Data Processor Conversion

I'm seeking a skilled developer to convert my existing NodeJS data processing program to Java. The current program is built on the Express.js framework and is primarily used for handling data.

Key Requirements:
- Proficient in both NodeJS and Java, with extensive experience in data processing.
- Familiar with the Express.js framework to understand the current program's structure and functionality.
- Expertise in Spring Boot, as this will be the primary library used for the conversion.

Ideal Skills:
- Strong understanding of data processing techniques and methodologies.
- Ability to translate NodeJS logic into Java effectively.
- Experience working with Express.js and Spring Boot.

Please note that the primary function of the program is data processing. The selected developer will need to ensure that the converted program retains the same functionality and efficiency as the original.
