By launching a website, then another, then another...

I am launching a website. I am not sure by launching a website can be called launching a startup. But this website is a web application. It is build on top of personally created architecure. Running on a very low cost of hosting. Very very low.
Here are a few websites that I have launched recently:
SaleRadar 1.0 - To help people discover any sales held around. Currently only in Malaysia. Where I am staying right now.
FoodRadar 1.0 - Same like SaleRadar, but for food. Only in Malaysia too. I have put the links to these websites in the navbar of this website too.
And the last one is this website that you are browsing now, MyRadar. Not really sure how to categorise this website. I would like to make a place where I can note my own work and research in programming.
These websites are created fully from scratch. I am not using any existing CMS. But still I am using AngularJS framework to make these run. And for the backend, well I would like to reveal it. But somehow I think it can be considered an intellectual property which most businesses highly protected if they have. So I am still thinking about this.
I am also planning to create a mobile apps for these websites too. A very flexible mobile application platform that can be built for many type of websites. In the future, I plan to generate more websites or web applications or mobile apps. I really hope these websites or apps could help anyone in someways.

As this article is migrated from my old blog, I would like to emphasize that this new website is not written with AngularJS. I started to develop most of my websites and apps regardless in which platfrom by using React. I keep some concepts I have used in developing those apps, but applied them with React way.
So these are new links to both apps;
Thanks for reading!
