Summary
🤩
Rockstar🎓
Top SchoolAnthony Rossi is a Senior Software Development Engineer with seven years of experience building secure, high-performance networking and cryptographic systems at Microsoft. He specializes in Windows kernel and transport-layer work—contributing to MsQuic (the cross-platform IETF QUIC implementation) where he implemented version negotiation, Schannel integration, client-certificate handling, and security-focused fuzz tests. His work has measurably improved Windows networking reliability and customer experience (including an 80% UPnP port-mapping speedup and Teredo reliability gains), and he has driven end-to-end testing of certificate and TPM attestation flows. Comfortable navigating undocumented legacy code, he combines systems-level rigor with practical product impact and a long-standing interest in Windows networking and security.
