JOB OVERVIEW

Urgent Java/Quarkus SOAP API Developer (Immediate Start - 1 Week Coverage)
Overview

I'm looking for an experienced Java backend developer who can start immediately (today or tomorrow) to temporarily cover for one of my developers who will be on leave until next Thursday.

This is not a greenfield project. The API is already 90–95% complete. Your job is to quickly learn the existing codebase, study the API documentation, answer developer questions, troubleshoot issues, and implement small changes as needed.

If you're someone who enjoys jumping into existing enterprise applications and getting productive quickly, I'd like to hear from you.
