I focus mostly on PHP ecosystem surface: static analysis, PHP internals, security of PHP applications. My open source work started a few years before AI agents became part of the picture; they've since become a useful accelerant, but the direction was already set. Below you can see some of my projects or the projects that I contribute to.
A fast language server for PHP, written in Rust.
A fast, incremental PHP static analyzer written in Rust. Many diagnostics rules covering types, dead code, and taint analysis.
Organization supporting the software supply chain security of non-profit organizations.
A PHP parser implemented in Rust, the foundation for the tooling above.
Various contribution spanning from session security improvements, improving performance of BCMath or trying to fix as many bugs as possible.
