Jon Smith [https://jvste.ch/] is a senior software engineer and security researcher with a focus on compilers, reverse engineering, and low-level systems development. His expertise spans multiple architectures and operating systems, with a particular emphasis on LLVM internals, static analysis tooling, and custom native code generation, including everything from shellcode and bootloaders to bespoke object file layouts. He has written custom compiler optimizations, firmware for embedded systems, and tooling for both offensive and defensive security applications. With a strong background in C, C++, and assembly, he often works at the intersection of language tooling and binary analysis, applying deep systems knowledge to practical engineering problems. He also maintains a public Twitch stream aimed at making vulnerability research accessible to newcomers without a formal computer science background.
