Any questions?

  • Do you code in ASP, .NET or C#?

    No, just PHP.

  • Do you code in PHP?

    Yes — I’ve been coding in PHP for over 20 years.

  • What do you use to build web applications?

    I develop web applications using Laravel — it’s a fantastic open-source PHP Framework for building web applications. I code in VS Code and I use GitHub to store my repos. For local development, I use Herd.

  • Do you know Javascript?

    Yes — I’ve been coding Javascript for over 25 years.

  • What’s the difference between a website and a web application?

    A website communicates a message to its users. A web application is a special kind of website that provides a service to its users, sometimes for a fee.

    Websites and web applications have a lot in common. They are built with much of the same technologies, but their purposes are often different.

    Web applications generally provides a Customer with a digital service of some kind, and more often than not, Customers must register for an account in order to use the web application. Sometimes, they pay a fee/subscription for the service — you might recognise the acronym SaaS which stands for Software as a Service.

    Mailchimp is an example of a web application. You need to register for an account in order to use it and you can use an extended set of features if you pay a fee.

    Of course, much of the Mailchimp.com is accessible to everyone — those are the bits that market the services provided in its web application.
