By far the two biggest projects I’m responsible for are:

• Phpactor: PHP Language Server.
• PhpBench: PHP Benchmarking and performance tool.

But I’ve written smaller projects which are actively used:

• Strava RS: TUI for Strava written in Rust.
• Pttlog: Plain Text Time Logger TUI written in Rust.
• Fink: Link checker.
• What Changed: Composer plugin to see what changed.
• Gherkin Lint: Gherkin Linter

Going back further in time:

• PHPCRShell: Shell for PHPCR (PHP version of the JCR content repository).
• Symfony CMF Routing Auto CMF component to automatically generate and manage routes.
