About

Hi, I’m Jonas Devlieghere, a software engineer passionate about compilers, debuggers, and the tools that power modern software development.

I’m currently an Engineering Manager at Apple, where I lead the Debugger Core (LLDB) team. My work focuses on building and maintaining tools that help developers understand, debug, and improve their code.

Before joining Apple, I worked at GuardSquare in Leuven, Belgium, where I co-created iXGuard, an LLVM-based obfuscator for iOS applications. That experience solidified my interest in low-level software.

I’ve been an active contributor to LLVM since 2016 and today serve as the lead maintainer of LLDB. Over the years, I collaborated with an amazing community of developers to push forward the state of debugging.

Beyond my day-to-day work, I’m a member of the DWARF Debugging Standard Committee and the LLVM Foundation Code of Conduct Committee . I’m also a reviewer for ACM Computing Reviews,

Don’t hesitate to get in touch with me at [email protected].
