About this gig

I am an experienced Java backend developer focusing on REST API development, database design and third-party system integration.


My core tech stack is Spring & Quarkus. I can build stable, maintainable backend logic including CRUD operations, user authentication, parameter validation and interface security control.


For lightweight auxiliary data processing tasks like data sorting, file format conversion and batch data reading, I provide simple Python scripts as supplementary tools. Large-scale complex Python project development is not within my service scope.


All delivered work follows clean coding standards. Standard & premium packages include fully annotated source code, database SQL files and step-by-step operation guides. I offer reasonable revision rounds to match your business demands.


If you need custom backend APIs, database logic or small data automation scripts, feel free to send me your detailed requirements before placing an order.
