Welcome to SHA

I'm S. T. Le (Dennis)


I am the co-founder and lead developer at RoseBlanc (roseblanc.com.au) and also an iOS developer here at SHA (sparrowhawkaus.com).

I enjoy building everything from small utility app to rich interactive and complex e-commerce apps. To help make someone’s life better and easier, that is what I do.

I would love to give away all my apps for free, but the truth is I need money to funds all those apps. If you are a developer, you'll know that no back-end server is running for free, a free app or service is not 100% free as you'll trade off your privacy and security for it.

There are a lot of cheap solution out there that I can use to host my back-end but I rather pay a high price for something that can protect your data. If you enjoy my apps, buy it and it would be nice if you can leave a review on the App Store.


* In the next few months, the website will be upgraded. The new website will include User Portal where users can manage and buy apps at lower price. All existing users can upgrade to a newer version of they bought without any extra fee. All information related to the switching process will be available on the new website.
