Hi, I’m Sii Cockerill — I’ve been building web applications since the early 2000s

I pride myself on making software that is easy-to-use as well as robust and secure. With a background in both design and development, I’m sure I can bring a unique appraoch to creating your next business application.

  • Sii played an integral part in building multiple websites and landing pages allowing us to remain competitive across all areas of marketing. I worked very closely with him on systems and trackings so we could monitor performance in greater detail than ever before. He will always add fresh ideas during any build resulting in a better than expected end result.

Any questions?

  • Do you code in ASP, .NET or C#?

    No, just PHP.

  • How much do you charge for a web application?

    Every web application is different — some are super simple and others are incredibly complex. Others look simple AND are also incredibly complex.

    I’m interested in delivering a web application that will make a real difference to your business, so if you’re interested in that too, get in touch and let me know what problems your new web application needs to address. I’ll email you some possible solutions and let you know a guide price so that you can see if it fits your budget.

    If you know what you want your application to do, and you have a set budget to get it all done with, let me know and I’ll tell you if it’s possible or not.

  • 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.

  • Can you help me with my CSS?

    Yes, but so can Stack Exchange… unless you’re particularly stuck on a very complicated CSS layout, you can probably find out the answer quicker and more cheaply via a Google search.

  • Can you help me add a DNS record?

    Yes. I can help with DNS. Though it’s rare for a client to start their relationship with this service alone.
