The hard skills of a front-end developer (junior, middle, senior)
Junior engineers should be able to check and fix small issues in the code of middle and senior staff members.
Junior staff members should be familiar with the existing architecture, its layers, and design patterns. A Middle coder’s responsibilities revolve around implementing new features and understanding design patterns and SOLID principles. Furthermore, a Senior developer must be skilled in adding new subsystems to the existing architecture, have extensive knowledge of design patterns, and be knowledgeable about architecture patterns.
Software development is incomplete without testing. Middle developers should be experts in test-driven development, while junior staff should be familiar with unit testing approaches. Lastly, Senior staff members should know about test automation frameworks like Protractor, Selenium Webdriver, etc.
Understanding of JS libraries (Angular and React)
Hard skills of a back-end developer (Junior, Middle, Senior)
Back-end specialists must review and fix code issues, just as front-end developers must.
In addition to understanding the existing architecture, back-end developers must work seamlessly with it. Junior developers should have a basic understanding of architecture layers and MVC (Model-View-Controller). Also, Middle developers need to understand common design patterns and SOLID principles to integrate new features into existing architectures.
Senior developers should be able to design an application architecture from scratch using specific technical and business requirements.
Software development teams use VCS (Version Control System) to simplify collaboration and keep track of all changes. Further, teams integrate their code into a mutual repository several times daily using continuous integration (CI).
