A little about us.

What do we do?

Terah is a software development firm specialising in PHP and ASP.NET web application development for small to large business. Terah design, prototype, implement, host and support custom applications using the latest cutting-edge and innovative web technologies.

Our Founding

Terah is owned and directed by Terry and Sarah Cullen and was formed over 10 years ago in 2009 after trading as ProPHP for four years. Terah consists of a small but professional team of project managers, administrators, developers and software testers


At Terah we keep like to keep project management as simple and as transparent as possible. Our company model ensures you'll deal directly with the person responsible for the success of your project. On commencement you will be assigned a project lead that will be your main contact throughout the duration of development. This approach eliminates miscommunication that often occurs between account manageres and clients in the the translation of project requirements and progress reporting. With Terah your main contact is the person bringing your project to life.
