Since Datamata Corporation has a single developer, I will write here from my first name, which is Evgeny Dolgy

In 2005 I started trading stocks with a simple proprietary program written in Java, and by 2008 I was running quite sophisticated application

Being mostly programmer, not a trader, I decided to get 'market advantage' in better code. I started a quest to re-factor existing application to a quintecential state, where it cannot be improved anymore

Very quickly I arrived to an idea of Hierarchical objects organization, the only structure with enough name space to accommodate "write once, call from everywhere" idea for every smallest piece of functionality. Later on I started writing complex classes in pieces, which lead to Package-Oriented Programming

Few years down the road Java API was pronounced "not perfect" and I started using custom collections and my own "perfect" wrappers to access what is in Java. This would also include java.swing and later javafx

In 2014, with Java8 released, I started massive switch to Streams processing and moving code to interfaces. Java interfaces, unlike traits in Scala, do not allow data (logic only). This "feature" makes all the interface code truly functional. I did not know this, but found out that interface code almost never had bugs, therefore would make the system better

In May 2016 I discovered Scala. I found that many things I was struggling with in Java, are actually part of the language and are done way better than my abilities would ever allow. Within a week I decided to ditch 15 years of Java experience and go all in on Scala

I was fascinated by the beauty of the language, but could not find a good fit for my code in Scala API, especially in GUI part. Therefore, like in Java, I had to create my own closed framework

It took a year to rewrite all the code and to get enough of Scala experience to see the big picture. And it looked bright, Scala had a natural fit to my hierarchical API, so I got an idea to release it as Scalqa

After another year of work, by May 2018, I had something to put on Github. At this time I realized, that to make any difference, Scalqa needed to deliver better performance

It took another 6 month to fully rewrite collections with specialized primitives and performance in mind. So, at the end of 2018 it feels like it is ready for public review
