As answered by people managing HackerRank and DevStack.co.nz.
DevStack.co.nz's answer:
DevStack is primarily designed for people working in property development, including property developers, development managers and other property professionals in Auckland and across New Zealand.
However, you don't need to be a professional developer to find it useful. Property owners, investors and anyone researching their next property purchase can use DevStack to learn about the tools, data and resources available to help them make better-informed property decisions.
DevStack.co.nz's answer:
DevStack hasn't tried to reinvent the wheel. It has vetted and identified which tools and resources are actually useful for property professionals working in Auckland and New Zealand.
Rather than being a long list of links, the tools are organised around the property development process, making it easier to find the right resource when you need it. The focus is on tools that are genuinely useful for property development, from site research and due diligence through to feasibility, planning, finance and construction.
DevStack.co.nz's answer:
DevStack is free to use, so rather than traditional customers, its users include property developers, builder-developers, property professionals, investors and property owners looking for better information and resources.
It's particularly useful for people involved in Auckland property development who want to understand what tools are available and how they can use them in real projects.
I also share practical examples of how I use AI in property development and construction. For developers and builder-developers who want to go further, I offer a separate guide covering 13 areas where I currently use AI to save time, improve workflows and get more from the information available to us in New Zealand.
DevStack.co.nz's answer:
None of the third-party tools listed on DevStack are my own. DevStack itself started as a side project while I was learning to build websites and improve SEO for my own businesses.
What started as a simple place to organise the property development tools I use every day gradually became a passion project. I found it so useful in my own work that I decided to make it available to other property developers and property professionals in New Zealand.
DevStack.co.nz's answer:
DevStack is an easy choice because it's free, requires no sign-up, and lets you customise your own toolkit by pinning the resources you use most often in whatever order works for you.
You can also save tools you don't use regularly but don't want to forget. Instead of keeping links scattered across bookmarks, emails, spreadsheets and notes, DevStack gives you one place for the property development tools and resources you actually use.
DevStack.co.nz's answer:
My background started with a university property degree, a BProp, followed by property valuations, development management, managing a subcontracting business, and eventually returning to property development.
Throughout that time, I used many of these tools constantly and realised I had links saved all over my computer. They were in email drafts, spreadsheets, notes, bookmarks and sticky notes. I wanted one consistent place I could trust to keep the tools I use, as well as the ones I only need occasionally but don't want to forget.
We're fortunate in Auckland to have a huge amount of property and development information readily available. The problem is that it can take some effort to find and extract it. DevStack grew from my own need to make that process easier.
