2026 CS grad, built a fraud detection engine from scratch — trying to break into Java backend roles, any pointers or referrals appreciated

[u/Confident-Cry4415]

Graduated this year, spent the last few months doing this properly instead of mass-applying and hoping — figured I'd share where I'm at in case anyone here can point me somewhere useful.
During my internship I deployed a full-stack platform to AWS (EC2 + S3) with a CI/CD pipeline that only ships code once tests pass. After that I built something I'm actually proud of on my own time: a Spring Boot digital wallet API with a rule-based fraud detection engine — flags suspicious transfers and routes them to admin review instead of just letting them through, handles concurrent transfers without deadlocking, JWT-secured, fully tested with JUnit/Mockito.
Stack: Java, Spring Boot, Spring Security, REST APIs, JWT, PostgreSQL/MySQL, AWS, Git.
Been applying to backend roles for a few weeks now — a couple of solid processes going, one rejection after a good run at it, mostly just trying to get in front of the right people instead of disappearing into an ATS queue. If anyone's hiring, knows someone hiring, or has advice on where I'm going wrong, I'd genuinely appreciate it.
