This blog is intended for software system engineers, architects and managers or people generally interested in development, testing and integration of software systems. It is part of profiq’s community effort that has the objective of sharing knowledge and ideas about software system integration, testing and development. In addition to this technical content, we share updates about life at profiq.


AI and AI-powered development have become incredibly hot topics in the technology industry. The potential of AI to revolutionize various fields is widely acknowledged, and while impressive, is still being developed. Researchers, developers, and organizations are actively exploring new ways to use AI. In this dynamic landscape, we at profiq are constantly seeking out and experimenting with new libraries, plugins, and tools that leverage AI. These resources aim to enhance productivity, automate repetitive tasks, and unlock new possibilities in software development. One such resource is GitHub Copilot (Copilot). Copilot is…

Integrate and setup in under 15 minutes

In the last blog post, I provided an overview of the Split Feature Experimentation Platform. In this post, I will show you how long it takes to integrate Split into the React web application. The best way to start the integration is by taking a look at their well-written documentation. You can also check out some simple project examples on their GitHub site.   I have created a quick video guide where I set up a new feature in the Split Management console, integrated it into my application, and tested everything in…

Real-time control of your app features with Split

At profiq, we often research and demo new and interesting modern technologies. One interesting Silicon Valley startup called Split ( caught our attention with its recent launch of the Feature Experimentation Platform. The Feature Experimentation Platform is intriguing because it lets developers rapidly iterate product features, target them to customers, and measure their impact in one unified solution. It consists of an SDK for various languages and a cloud service console that lets you control and monitor features of an application in real time. Because we could potentially use this…

Petr Večeřa, a software engineer at profiq specializing in test engineering, shares his thoughts on his role as a technical QA and test engineer. Petr started at profiq three years ago in the Tech Research position where his task was to develop a prototype of test automation for a company from Silicon Valley. Now he is in charge of one of the QA teams and he is responsible for several products. Q: Your position is called a Software Engineer but its goal is testing – how does it go together?…

Kubernetes cluster setup using virtual machines

Preface Recently I needed to setup k8s cluster on my local machine in order to see if I'm able to do it on bare-metal servers lately. So I decided to first give it a shot using Virtual Box machines. There were a few places where I was a bit stuck and spent some times googling. This article should summarize all of the problems and give you solution. Most of knowledge used here can be found in official kubernetes documentation. I will also show you how to configure your virtual machines…

Why didn’t you tell me!

Here comes a testing focused article after a series of technical blogs! It is based on experience with projects managed through waterfall processes and it continues the series about tackling test complexity. It is about a luxury that we so often ask for and we often don't have in testing: to be involved early in the product development process. What does it mean actually to be involved early in the process? Why is it so important? And how does it help tackling test complexity anyway? (more…)

Knowing your subject

This article follows-up with the series of  articles about tackling test complexity, adding a view on the importance of product knowledge, when coping with the complexity of testing. Let's assume that you understand already, who your customers are;) I managed testing of a large integrated suite of software products on one of my past projects. Each product had its years of individual history already, when the decision was made to release them as a suite. And each of them was quite complex on its own, even without considering integration with…
