Developed HTTP/2 support for the confluentinc/rest-utils repository by introducing a BouncyCastleServerALPNProcessor, enabling secure ALPN negotiation when using the BouncyCastle FIPS JSSE provider. This work extended Jetty’s JDK9ServerALPNProcessor and incorporated runtime detection of the BouncyCastle SSLEngine to ensure seamless HTTP/2 handshakes within FIPS-compliant environments. The implementation focused on backend development and cryptography, leveraging Java and SSL/TLS protocols to meet security and compliance requirements. Additionally, the feature was backported to the 7.5.x branch to maintain consistency across releases, demonstrating attention to long-term maintainability and alignment with evolving security standards in enterprise Java applications.
