Are you able to host a website?

Sustainable Processes
At Greenstone Technology, we believe that great software is built on strong foundations — and that begins with a well-structured development process. Our team of experienced software developers in Christchurch follows a proven Agile methodology to guide projects from concept to completion. This approach ensures transparency, collaboration, and continuous improvement at every stage.
Planning
Every successful project begins with a clear roadmap. Through software consultation and project planning, we work closely with you to define your goals, requirements, and the best path forward. This phase ensures that your vision is fully understood and strategically aligned with your business objectives.
Prototype
We bring your ideas to life early in the process using interactive prototypes. As part of our design service, prototyping allows you to preview and refine the user experience before development begins — saving time, reducing risks, and improving clarity.
Testing
Quality assurance is embedded into every stage of our process. We rigorously test and validate prototypes and software builds using real-world feedback. This iterative testing loop is a cornerstone of Agile development and helps us deliver polished, high-performing solutions.
Build
With a clear plan and validated prototype, we move into full development. Our team builds your software using modern, scalable technologies — all while continuing to test and refine as we go. The result is a reliable, flexible, and future-ready software product tailored to your evolving needs.
Our Contributions
In addition to the software lifecycle insights available through Greenstone, Ryan actively contributes to the developer community through his technical blog, iOS Cookbook. This platform features practical tutorials, in-depth articles, and real-world examples designed to help mobile developers grow their skills — particularly in iOS and cross-platform development. In an industry where tools and best practices evolve rapidly, sharing knowledge is essential. We’re proud that iOS Cookbook has become a trusted resource for thousands of developers worldwide.
