Summary
👤
Senior🎓
Top SchoolMatteo Brancaleoni is an R&D Director with 20 years of experience building high-availability VoIP, softswitch and WebRTC video conferencing systems from the Linux server up through embedded hardware. He leads a multidisciplinary team in Milan, combining hands-on development in Elixir/Erlang, Python and Typescript with hardware and OSS integration for VoIP–PSTN and VoIP–GSM gateways. Early roots as a Linux sysadmin and security-focused work on ecommerce services give him a pragmatic, security-aware approach to telecom reliability. A long-time contributor to FreeSWITCH components (notably ftmod_libpri) he’s improved ISDN/PRI and SIP behaviors, T.38 and calling-number handling—work that underpins real-world carrier integrations. He’s equally comfortable designing PCI hardware and running clustered Linux services, and often bridges open-source telephony ecosystems with production-grade commercial products.
