Sadly, after 8.5 amazing years, my Mozilla dream has come to and end. Excited for the next dream though! If you're looking for a passionate, web-loving engineer, shoot me a DM or email. #mozillalifeboat ❤️

mega php tip: use #[SensitiveParameter] for sensitive parameters.. php will hide its value in stack traces, error messages, and logs.. this prevents accidental leaks of secrets in production.. absolute chef's kiss tip.. ✨
