Frequently Asked Questions

Answers to the burning questions in your mind.

Most often we use flexible development methods such as Scrum or Canban, but also we can work on Waterfall. The choice of approach depends on the willingness of our partners to communicate with the project team, the readiness for changes and risks in the development process, and other features of each particular project.

Depending on the project goals and objectives, the team includes the following specialists:

  • Analyst
  • Designer
  • Technical Leader / System architect
  • Project Manager
  • Developers (web / front-end, back-end / server side, mobile, etc.)
  • Testing Specialists or QA (QualityAssurance)
  • DevOps or System administrators
  • Others as needed (Datascientists, experts, etc.)

Before a project commences, there will be thorough consultation with the customer. You will have the opportunity to learn about the experience the team members bring to the project, and we will decide upon the technical requirements together. When we sign a contract for custom development, we guarantee the implementation of all the functionality described in the Technical Requirements for the time and budget specified in the contract.

Working with us, you get a team that transforms your idea into high-quality software. A successful product, in our opinion, must meet three criteria: 

  1. Designed in accordance with your requirements and wishes – you are satisfied with the result both in technical and emotional criteria.
  2. Done right – all functions described in the Technical Requirements are implemented and function correctly.

  3. The project was properly managed – you walk away with working software (information system) and source codes with a necessary level of comments and project documentation which make it possible to further develop the project with either us or a third-party team.

The time and cost of development depends on several elements:

  • Scope of work described in the Technical Requirements;
  • The number of specialists involved in the project;
  • Technical readiness of other customers’ information systems.

We are often approached by innovative entrepreneurs who have great ideas but lack the technical expertise to develop them. This is not a problem: our business analysts and project managers have a thorough understanding of business processes and ideas and are able to formulate tasks in a technical language.

While working on a project, you are in contact mainly with the project manager and analyst. During the demo days, other specialists are also involved to jointly discuss key project details as necessary.
