Payroll Development for Existing App

Job ID: 37665990

Budget: $250 – $750 USD

I'm seeking an experienced developer to aid in payroll development for an application I've previously developed. Your work requires proficiency in both Java and SQL, specifically connecting the new tool with SDK (Software Development Kit) or API (Application Programming Interface).
Use case is on test server platform.

The main functionalities I need are:
- Payroll processing, to accurately manage contractor and employees' pay as a recruiter for many entities and track work hours effectively.

Ideal skills include:
- Prior experience in developing payroll systems.
- Proficiency in Java and SQL.
- Experience working with SDK or API for seamless system integration.

Although I've skipped the question on specific requirements or regulations for payroll calculations, it'd be beneficial if you're acquainted with common payroll calculations and regulations just in case I may need this in the future.
