I will build or fix java spring boot, nodejs, or go rest apis

Need a reliable backend API built, extended, or fixed? I develop focused REST APIs in Java Spring Boot, Node.js, or Go whether you have an existing repo or need a new service.

What I do: Build or extend REST endpoints with clean structure Wire MongoDB, PostgreSQL, or Redis Add auth, validation, and automated tests Package with Docker when needed Troubleshoot bugs and broken endpoints

Every package includes source code.

What to send: repo access or requirements, sample requests/responses, and any error logs.

Why me: I work daily with Spring Boot, Node.js, Go, MongoDB, PostgreSQL, Redis, and Docker on production backends.

Message me before ordering Premium or any production-facing work so we can confirm scope and stack.
