CLOSEIT BLOG

In the heart of software development, in the city Brno, we launched a blog about IT.

Coalescence of Business & IT And The Delayed Train

I was wondering since I am in a business and since I am in an IT, why these two sectors were seen separately for such a long time. It seems last few years people started realising they can work together. Nowadays, they are many companies based simply on the digital products, look at Airbnb, Uber, Google, Spotify.. without the technology and some algorithms plus great programmers they are nothing.

Continuous Integration (CI)

Let's face the Continuous Integration the development practice that requires developers to integrate code into a shared repository at least once a day per developer. Each check-in is then verified by an automated build, allowing teams to detect problems early. 

Agile in a Kitchen or Design?

My two favorite topics just next to the technology are food and design. I love both and I think about both of them most of the time. Therefore, a question appeared in my head: "Does Agile works just for software development or is it a way of workflow management also in any other areas we will choose?"

The Curse of String Distance

When you work for sometime on a larger project, you may realize it doesn't perform as well as it did. That is usually expected but sometimes, it just doesn't feel justified. This was also our case and because the performance of the project was important, we had to get our hands dirty with profilers and debuggers. Of course, we found a few bottlenecks.

Does Scrum Save Your Business?

I used to have startup developing a mobile application. We were two people working hard and at some point successfully, even though we were a big mess. Both of us doing things from design, to coding, to management, to marketing to planning everything needed. Yes, it is a typical startup mess, that we loved.

PDI SAS Reader

If you work in FinTech, sooner or later (but probably sooner) SAS data set will get into your project. In a field dominated by one system, there is hardly a place for rejection. Unfortunately, for small companies it is very hard to integrate SAS in their stack. In our projects, we use ETL to gather data from different sources. To be more precise, we use open source tool Pentaho Data Integration.

Null Checking in MongoDB

When we started using MongoDB in our projects, I was very confused by aggregations. But I wrote so many of them at this point, I actually enjoy putting them together. At least I enjoy it more than writing SQL queries. Yet there is one thing I have to process for a while in my mind every time - how to do null checking and field existence checking.

Does a Developer Must Have a Pet Project?

Having a pet project - a project being developed in your free time - can be a lot of fun. Give me a free week and option between spending the whole time on the beach or the possibility to work on my stuff, I will probably take #2. Don't get me wrong, who doesn't like a vacation? But when as the idle time raises, I'm getting bored and the itch to work on my pet projects grows.

Credit Risk Stress Testing Framework

We have created a unique solution for recurring stress tests in credit risk Raiffeisen Bank International, which allows us to define our own test scenarios for simulation of portfolio development and calculations of individual Risk Parameters RWA or ECL. Our application was successfully used for EBA stress tests in 2018 and continues to be extensively used for other stress testing needs by internal or required controllers.
