JavaScript Salaries, Rates, and Team Costs Review Comparison USA and Ukraine

The main tasks are to lay down the correct architecture of the project in accordance with the requirements of the development and scalability of the project, control and make decisions regarding the frameworks, libraries and technologies used. As the ice is responsible for the composition of the team, the distribution of tasks according to the skills of the team and coordination within the team.

On a project, as a rule, a senior developer is responsible for creating the main components of the project in accordance with the laid down architecture, controlling their quality, compatibility and maximum performance in accordance with the assigned tasks. In addition, he takes an active part in the development of architecture and the distribution of tasks within the project.

The main tasks of these developers are the development of small project components and the development of existing components. Simply put, this is an independent work on tasks of average complexity in accordance with the laid down architecture. In fact, on every project there are about 50% of such tasks, where complex architectural solutions are not required.

The main tasks of these developers is to help develop parts of components or pattern blocks of a project. Junior programmers work under the strict supervision of senior engineers, in fact, they are assistants to developers on the project and help to perform more routine tasks, thereby saving the senior’s time and delay. Often in projects such tasks are from 20% to 40%.

In order to work effectively as a team and achieve goals, you need the role of a Business Analyst who works with the Product Owner and describes the basic requirements of the project, user stories and exception criteria for individual components and blocks, and working with the team to explain how a particular component works. The role of Project Manager is more to coordinate the work within the team, sort resources, and control the quality and speed of development. Typically, the project manager role is replaced by the Scrum Master role in the Agile projects.
Depending on the type of project and the size of the team, these roles can be combined by one specialist, or they can be divided among different specialists.

The tasks of the Lead PM / BA are to control the quality and efficiency of the development process, set up the work process for a new project, plan scaling, composition of the delivery team, coordinate PM, BA, QA on the project.
The main difference in skills between the lead and PM / BA is the skills of managing distributed teams, more than 4 years of experience and practical skills in establishing delivery processes.

This position is required to save time for developers, PM / BA and Product Owner on a project, as well as to analyze all dependencies when creating new product features and to minimize the number of bugs in production.

This position is especially important in the later stages of product development. Automating the testing process significantly saves the team’s time for testing and deploying new versions of the product, and also significantly reduces the number of bugs in production and prevents significant disruptions in the finished product after the deployment of new versions.

The main tasks of a UX designer are to work closely with a Business Analyst on a project and create user interfaces for the future product.
When working on UX, designers analyze the basic needs of users and the relationship between the main modules of the product to create the most convenient interface.
It is also important to understand the principles of front-end development and work according to the capabilities of the selected technologies and the environment in which the main development of the front-end team is carried out.

Among the main responsibilities of DevOps on a project are continuous integration and delivery (CI / CD), server deployment automation (IaC), monitoring, reporting, and working closely with backend engineers to develop the most effective solution that meets product requirements.

In Javascript, Frontend Teams can develop both web and mobile, using technologies such as React Native. In modern development, it is supposed to work closely with the backend teams that develop the API, transfer the necessary endpoints for the development of frontend components that are independent of the backend.

The main tasks of the backend team are creating a scalable backend architecture, working with databases, developing the platform API and the necessary endpoints for developing the frontend. Moreover, if web and mobile are developed using hybrid technologies such as React Native, very often one backend team is able to work with several frontend teams.
The back-end team is assembled according to the same principle as the front-end team. Truthfully, except for the skills of the chosen framework, specialists with skills in working and optimizing databases are often needed. And also the attraction of DevOps for high-quality configuration and optimization of the server or cloud solution. In small teams DevOps may be partially involved.

As a rule, in a full-stack team consisting of front-end and back-end developers, we will single out a PM in a separate role, who is responsible for the interaction and development process of the entire team.
In addition, we have introduced such positions as CTO as a Service, Delivery Manager as a Service, which allow projects to attract maximum expertise for development, while not spending expensive specialists on full-time in the team for permanent work.
