LL1 automat in Racket/Scheme et least 5 rules

Hello, I am looking for a developer who can help me build an LL1 automat with at least 5 rules. This project will require some refactoring of existing code and needs to be done in Racket/Scheme. The system needs to follow 4-7 rules and should provide a robust, reliable output. The solution will need to be tested and validated to ensure it's functioning properly. If you have experience in programming automata, I would love to hear from you and discuss further about this project. I am looking forward to your proposals!
