Rockstar🎓
Top SchoolPhilip Balister is an embedded systems developer with 19 years of experience specializing in software-defined radio, cross-compilation, and Linux build systems. He combines deep hands-on expertise in C/C++/Python and ARM/OMAP architectures with significant contributions to high-profile open-source projects like GNU Radio, OpenEmbedded/Yocto, and the USRP UHD driver. As Principal of OpenSDR and a Yocto Project advisory board member, he has led ports of SCA frameworks to embedded platforms, optimized NEON routines, and created OpenEmbedded recipes and toolchains for complex IoT builds. Based in Blacksburg, Virginia, he pairs academic training (MS EE, Virginia Tech) with practical system-level engineering—often solving subtle build and compatibility issues that unlock SDRs on constrained hardware.
