Rockstar🎓
Top SchoolYoshiyuki Kurauchi is a software engineer with 11 years of experience specializing in telecom, networking, and security, now working at Cisco after its acquisition of Working Group Two. He has deep protocol-level expertise demonstrated by contributions to Wireshark—improving PFCP dissector accuracy—and to a native Go OPC-UA library, where he implemented security headers and channel services. Comfortable across backend systems and mobile infrastructure, he has balanced hands-on engineering roles with product management experience at LTE-X. Based in Greater Stockholm, he brings a pragmatic, cross-cultural perspective from remote work in Japan to hybrid teams in Sweden. Notably, he combined protocol debugging finesse with practical implementation work, fixing subtle encoding/length bugs that improve real-world packet analysis.

Contributions summary:Yoshiyuki primarily focused on modifying and improving the PFCP dissector within the Wireshark project. Their contributions included fixing incorrect field lengths, addressing encoding issues, and correcting dissections of various information elements (IEs) within the protocol, like Trace Information and Ethertype. These changes involved renaming several IEs to correct naming conventions and ensure accurate protocol analysis. The work resulted in a more accurate and reliable dissection of PFCP packets.
