Web Development

Web Development Overview

At Serina Systems we design and build websites that do far more than look good. Every site is crafted around your business goals: fast to load, easy to use on any phone and ready to be found on Google. Whether you are a small shop going online for the first time or an established company that needs a custom platform, we plan, design, build and support it from start to finish.

On the front end we write clean HTML, CSS and JavaScript so your pages stay light and quick. When your project needs logins, databases or admin tools, we build the back end with Node.js, Express and PostgreSQL. And if you want to edit content yourself, we can deliver a WordPress site tailored to your brand.

  • Custom, mobile-first design
  • Fast-loading, optimised pages
  • SEO-ready page structure
  • Secure forms and SSL
  • Easy content management
  • Training and ongoing support
