Senior Laravel Developer

To apply, please answer the following Laravel/Vue question:

Imagine you are building a custom event registration form in a Laravel and Vue.js application. The form includes dynamic fields that can be added or removed by the user. These dynamic fields are defined in a JSON configuration file.

Your task is to create a Vue component that reads the JSON configuration and renders the form fields accordingly. The component should also handle form submission, sending the data to a Laravel API endpoint for processing.

Please provide a high-level overview of how you would approach this task, including:
1. How you would structure the Vue component and handle the dynamic rendering of form fields based on the JSON configuration.
2. How you would manage the form state and handle form submission using Vue.js.
3. How you would design the Laravel API endpoint to receive and process the form data.
4. How you would ensure the security and validation of the form data on both the frontend and backend.

Please also discuss any potential challenges you foresee in implementing this solution and how you would address them.

Additionally, please mention the number of years you have been working with Laravel and Vue.js and provide examples of similar projects you have worked on in the past.

We look forward to reviewing your application and discussing your approach to this problem in more detail during the technical interview.
