What We Do

As a web development company, we specialize in programming services. The Kolosek team consists of development and designer teams which make sure that clients get to fully experience our product development process—from coming up with a project idea, to design and front-end development, all the way to back-end development.

We are fully committed to creating great web and mobile apps that have value for the user. This means making sure that we write quality code which will be presented through excellent user experience.

Web development

We develop state-of-the-art front-end and back-end systems. Why state-of-the-art?

Because every web app we create is a unique piece of work which our team, in cooperation with the client, has dedicated its time to. Our developers and designers are there to find the best and the most creative solutions for you (our clients) and help you end up with a reliable product and user experience.

Remember: a web app can become great only when all of its features have been adjusted to the end user's eye.

Mobile development

Mobile apps are timeless. With their number constantly rising, we make sure to deliver an amazing experience combined with high performance across multiple platforms.

Just like we do with web apps, we build custom mobile apps following our client’s needs and requirements.

When it comes to mobile apps, we use React Native development, but in order to keep up with the trends, we also use Swift for iOS apps and Java for Android.

In case you are looking to expand your web-based app to a mobile version, we will be happy to help you.

User experience

A good user experience should speak to the end user's emotions. Why? Because it's your user's perception of the product that is going to set you apart from all the other apps out there and your competition.

We understand this pretty well which is why, aside from our programming services, we also offer the help of our design team and their skills. They are there to help you create a UX like no other and, ultimately, increase your conversion rates, overall customer satisfaction, and make your brand more recognizable.

Creating beautiful and usable interfaces that are easy on the eye and a joy to use is our goal.
