Refactor Code for your Java project
Expert refactor code for Java applications. We find and fix Java-specific bugs and security issues that affect production apps. From $19.
Java refactor code issues we find
Common refactor code problems specific to Java applications.
SQL injection via string concatenation
Building SQL queries with string concatenation instead of PreparedStatement or parameterized JPA queries, allowing attackers to manipulate database operations.
Missing input validation
Controller endpoints accept request bodies without Bean Validation annotations (@Valid, @NotNull, @Size), allowing malformed data into business logic.
Thread safety issues
Mutable shared state accessed from multiple threads without synchronization, volatile, or concurrent collections — causing race conditions in production.
Swallowed exceptions
Empty catch blocks or catch-and-log-only patterns that hide errors, making bugs nearly impossible to diagnose in production.
Missing dependency injection
Direct instantiation with 'new' instead of Spring-managed beans, bypassing AOP, transaction management, and testability.
What our Java refactor code covers
Component restructuring
Breaking down god components into focused, reusable pieces with clear responsibilities.
Code deduplication
Identifying and consolidating repeated logic into shared utilities and hooks.
Architecture improvement
Separating concerns — UI from business logic, data fetching from rendering, config from code.
Type safety
Adding or improving TypeScript types to catch bugs at compile time instead of runtime.
Error handling patterns
Implementing consistent error handling, logging, and user-facing error messages throughout the app.
Dependency cleanup
Removing unused packages, updating outdated dependencies, and consolidating redundant libraries.
