Websites

A custom site for a small business, built from scratch to load fast on any phone and be easy to find on Google.

  • Designed for your business, not a template
  • Contact form that sends enquiries to your inbox
  • Set up to be found on Google: page titles, descriptions and a sitemap

Like the site I built for LenBuild in Guyra.

  • Fixing or improving an existing codebase, or contract work alongside your team

Like Fuel Finder, built on live NSW FuelCheck data.

03 / Kind words

  • We are extremely pleased with the website Calvin developed for us.

    From the beginning, we had very little understanding of how to create a website, but Calvin made the entire process simple and stress‑free. His communication, expertise, and attention to detail were outstanding. The finished website is modern, functional, and exactly what we needed. We highly recommend Calvin’s services.
