Worked on the spatie/laravel-csp repository to expand secure Content Security Policy (CSP) support by developing three new CSP presets for Intercom, Google TLDs, and Posthog. Implemented each preset as a dedicated PHP class, updated documentation to guide integration, and refactored domain configuration logic to reduce misconfigurations and improve developer experience. Enhanced test coverage using PHPUnit by introducing snapshot tests to validate CSP directives for all new presets. Focused on backend development and security, the work emphasized maintainability and clarity, ensuring that CSP policies are robust, easy to configure, and well-documented for users of the Laravel CSP package.
