About this gig

Need a third-party API connected to your web app without breaking what already works?


I will integrate a documented REST API into your existing application. I specialize in Java and Spring Boot backend development and can also connect the integration to an existing frontend screen when the stack and package scope allow it.


Depending on your package, I can:

Connect your backend to a third-party API

Handle requests, responses, data mapping, and basic errors

Connect the result to an existing frontend screen or flow

Add tests and deliver the updated source code


Whether you need to display external data, send information to another service, or add a new feature powered by an API, I will focus on an integration that fits your current codebase.


Please message me before ordering with your application stack, the API documentation, and a short description of the desired result. This lets me confirm the scope and recommend the right package.


OAuth flows, webhooks, database changes, new UI designs, and deployment require a custom quote.
