PROFILE

Peter Szij

Over a three-month period, contributed to privacy and reliability features across getsentry/sentry-java and walt-id/waltid-identity. Developed default masking for camera previews in Sentry Replay by integrating androidx.camera.view.PreviewView, updating ProGuard rules and changelogs using Java and Kotlin. In walt-id/waltid-identity, stabilized the Wallet API by resolving classpath collisions and implementing a custom UUID serializer to maintain compatibility. Enhanced CI/CD reliability by hardening Dockerfiles, pinning dependencies, and improving health checks, while advancing OpenID Connect verification with robust error handling and idempotency safeguards. Demonstrated strengths in backend development, containerization, and API testing, delivering measurable improvements in stability and maintainability.
