Our technologies, services and competences

Web development

We develop web applications and services using the most popular and effective frameworks. We provide you with the full range of competences with our business analysts, UX/UI specialists, architects, programmers, testers, DevOps, and admins. We can design, develop, but also maintain your product and make sure it keeps working exactly as you expect it to.

Backend Development

We have done a lot of projects and we know how to make scalable, stable, and efficient products. We take advantage of cloud environments, databases, and external services to meet your and your client’s expectations.

Mobile Apps

We develop mobile applications for both iOS and Android using well-tested technologies and best software production practices. Most of the time we build things from the ground up, but we also help in developing, maintaining, and supporting existing projects.

UI/UX Design

Nowadays, every application needs to meet certain standards when it goes to the user interface. We know all about it.

Research & Discovery

Our experience shows that coming up with an idea of a project does not necessarily mean having a clear concept of it. That is why we provide our clients with intensive workshops resulting in a well-organized and precise image of the planned undertaking. For a day or two our business analysts, UX/UI specialists, and architects learn about the clients’ expectations, determine the primary goals, and devise a clear-cut strategy for realizing the project.

Consulting and Code Auditing

We enjoy sharing our experience in creating and optimizing software, therefore, we audit our clients’ solutions regarding security, quality, and usability. We approach the job as thoroughly as possible, which is why specialists from all of our competence centers are engaged in the process.

Our project standards

Responsive Web Design

Responsive Web Design means that websites automatically adjust their content to the devices used to display it.


Designing architecture of a solution we focus on optimizing its efficiency and resource usage to make it well adjusted to high work loads.
Each of our projects is consulted with our architects, as we treat every project individually and do not leave anything to chance.
We have experience in developing both on-premise and cloud applications, and we are Google and Microsoft partners.

Developing Environment

We produce our projects using industry standard tools and field-tested methodologies:

Quality Control

A well planned and organized test environment is key in developing a high-quality product. Every project includes both automated and manual testing phases.

Implementation and Maintenance

Implementing the product often proves to be the most important part of a project. That is why we never leave our clients alone with such things – depending on the project we provide them with expertise, support, maintenance, and possibly further development, based on a variety of SLA options.

Good Practices

Apart from typical development standards, such as tool sets, environments, and quality control, we follow our own set of rules and practices, which we keep on improving.

  • code of conduct,
  • code review,
  • pair programming.

Ethics and Partnership

Technical knowledge is very important. But it means little without the right values and approach towards the client. We consider fairness and honesty indispensable to any successful co-operation, be it between us and the clients, or within our company. We conduct our projects in a transparent way – you have access to all of the products and information within the project at all times.

Our Partners

Models of co-operation


We agree to a certain budget, time, and work span, and take the whole project upon ourselves. In this case we typicaly start with preparing a project analysis and setting the success criteria. The results of our work are presented to you on a regular basis during our meetings.


The driving force behind this solution is the fact that we focus on the business results coming from the project regardless of the initial assumptions. This way we can combine two different approaches – we perform the analysis but treat it rather as a guideline instead of the ultimate goal. In this case you can influence the shape and form of the ongoing project.


We account for the time spent on realizing your project, based on rates agreed to prior to the project's launch. In this case you can freely adjust the speed and cost of the project on-the-fly.
