Java app built with Devin? Let’s review it.
Expert code review for Java apps built with Devin. We find Devin-specific bugs, fix Java security issues, and optimize performance. From $19.
Devin issues we find in Java projects
Problems specific to Devin's code generation patterns when building Java apps.
Autonomous security decisions
Devin makes security-related decisions without human review — choosing auth strategies, setting permissions, and configuring access controls that may be inadequate.
Compounding architectural errors
When Devin makes an early architectural mistake, it builds subsequent features on top of it. By the time you notice, the issue is deeply embedded in the codebase.
Workarounds instead of fixes
When Devin encounters an error, it sometimes adds workarounds that mask the root cause rather than fixing the underlying issue.
Inefficient retry patterns
Devin's debugging approach sometimes results in retry logic and fallback patterns that hide errors rather than resolving them, impacting performance.
Java issues we check for
Common Java problems that affect production readiness.
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.
Resource leaks
Database connections, streams, and file handles opened without try-with-resources, leading to connection pool exhaustion and OutOfMemoryErrors.

Frequently asked questions
Can you review Java code generated by Devin?
Yes. We regularly audit Java projects built with Devin and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What Java issues does Devin typically create?
Common issues in Devin-generated Java code include: autonomous security decisions, compounding architectural errors, workarounds instead of fixes. Combined with Java-specific concerns like sql injection via string concatenation and missing input validation.
How do I make my Devin Java project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Devin-built Java projects, the typical path is: fix security gaps, address Java-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review Devin-generated Java code?
Our code audit starts at $19 and covers security, performance, architecture, and deployment readiness. For fixes, our Fix & Ship plan is $199. Larger projects get a custom fixed quote — no hourly billing or surprises.
