Comfortable communication on the project makes the work productive, efficient and effective. To make joint decisions, solve problems and discuss ideas, Slack was chosen as the most convenient messenger for all project participants. This allowed us to quickly resolve emerging issues, propose solutions and constantly be in touch with the entire development team and customer.

Business Process Mapping


Work on a project always starts with setting goals and objectives. The main expectations and visions for the finished product are identified too. Next, we begin data collection and analysis. The target audience, its needs are revealed. Competitors are also carefully studied, existing solutions are determined and their analysis is carried out. At this stage, the main possible barriers and risks are determined and solutions for them is selected.


Next, we begin to build a high-level architecture, define a set of templates and tools. A technology stack is selected for the project, taking into account the features of the tasks, and the future functionality of the finished application. At this stage, a project specification that can be divided into different scenarios depending on the type of application and industry is created. Moreover, an interactive prototype is developing on this stage - a convenient tool that allows to evaluate the capabilities of a future application, discuss full and limited functionality, add new options.


Further, a team of specialists is formed to work on the project. The number of experts necessary for the timely completion of tasks is determined. The first meeting of the new team is conducted. The development process is carried out according to the written specification and the selected project methodology. After assigning tasks to performers, the project manager carefully monitors their implementation. Testing takes place at the end of each development phase, which allows us to produce finished products of high quality. In the final, automatic and manual testing is also conducted.

Business Process mapping was performed in conformity with ISO 9001:2015 quality management standards followed by Computools on all projects.

Interactive Prototype

One of the important stages of the project is the creation of an interactive prototype. This is a dynamic layout that allows testing the functions of the future application in a simplified form. At this stage, the foundations of the future design are laid and the main features of the application are discussed. An interactive prototype serves as a convenient and useful tool for clearly explaining some development points, identifying additional tasks and goals. Using this example, possible risks and obstacles are also identified.

React was chosen because it is the main stack the client team worked with. Moreover, the expansion of the Team was much easier than with other libraries or frameworks. It is also one of the fastest solutions on the market with huge support from both Facebook and the community.


MobX was chosen because of the more flexible service approach for solving business problems on the project. Instead of Flux which promotes Redux.


Typescript was chosen because it greatly helps to avoid unnecessary errors during development. The beginning of the project is a little delayed due to the initial settings, but then further development and support of the current code becomes much easier than without typescript. Also, adding a new developer to the team will not require additional time to understand what data structures come to us and what and where is used because of types and interfaces.


Node.js was chosen as the microservice architecture was conceived. Writing small services on node.js is fast enough and the Team extension is also quite simple. Besides, the customer team had more experienced specialists in this technology.

System architecture


A project specification is created at the design and interactive prototyping stages. The functionality of the application is described in detail, but not redundantly; acceptance criteria and restrictions imposed on them are also mandatory. Loading speed, security and other important criteria for evaluating the finished product are also indicated.

Goal - Create VR optimized runner with non standard controls + support realtime light and physics inside wheelbarrow.
Precondition Open game, start to play, do not collide with any obstacles or monsters. You can collect mushrooms and different by color crystals. Can spend blue crystal to boost your speed for a short time.
Main Flow Open your game Collect crystals
Postconditions Update your wheelbarrow and collect more crystals, buy shield packages and boost packs. Alternative Flows 1. You die in game -> watch ads, or use IAP 2. You update your wheelbarrow and collect more crystals


Building a team is a crucial stage in the development of a new application. Computools carefully selects employees to work on the project. We take into account the skills and knowledge of the necessary technologies, experience, and level of expertise in working on similar projects. The team is supplemented by the necessary specialists, depending on the tasks and needs of the project.

The development process at Computools is creative and innovative. Even with the use of ready-made or well-known solutions, the execution of tasks may require additional ideas and their implementation.

Dev meetings
Well-coordinated collaboration at all stages of the coding and testing process increases the pace of the development. This works especially well when our software engineers cooperate closely with their client counterparts.
The brainstorming sessions help our engineers to find a really innovative solution. Our company uses the latest technology for brainstorming, sharing experiences and ideas. Thanks to this, our teams are so effective and efficient.
Feedback Session
At the end of each sprint, we conduct team discussions and arrange feedback sessions. By exchanging opinions and emerging ideas, our developers find truly innovative solutions, improving their personal efficiency and the efficiency of the entire team.

Internal Communication Flow

The internal communication system allows the team to keep in touch, solve pressing issues and tasks in real-time. For this purpose, Skype was used, which significantly accelerated decision-making. Project management was carried out through a Jira, where the project manager distributed tasks between the executors and monitored their status and execution. Such a system allows the team to work closely together, while maintaining efficiency and productivity throughout the project.

Project Management Methodology

Scrum professes a team approach, short iterations and continuous improvement in the process. These principles are implemented through a set of special roles, rules, processes and tools, thanks to which teams produce products twice as fast. Scrum is based on a team or group - a well-coordinated team of professionals. Scrum teams are autonomous, the participants decide how to complete the task. They are multifunctional - the knowledge and skills of team members are enough to solve the problem.

Computools uses a standard git-flow method with only one difference - there is no team lead. The code is verified by each member of the Team. Edits or improvements may be suggested during the review. After the feature is ready, the code is checked by UI and Unit tests. If the tests pass, there is a merge in the development branch, after which the tests are re-run and automatic deployment to the remote server of the finished code occurs.
