What does a backend developer do?

The responsibility of a backend developer includes everything related to server-side software development. However, depending on the characteristics of a particular project, the technology stack and the organization of work in a team, such a specialist can solve different problems. As a rule, his responsibilities include:

• Development and support of server logic. Design of technical architecture and implementation of software business logic, which consists of a system of algorithms, software mechanisms and APIs.
• Database management. Organizing the work of databases in accordance with the needs of the project, writing queries and optimizing their performance.
• Creation of integrations with external services. Setting up APIs for third-party services, as well as organizing the processing and storage of data received from external sources.
• Performance optimization. Monitoring and increasing the speed of server response to user requests.
• Security. Take measures to reliably protect user data and prevent attacks such as SQL injection, XSS and CSRF.
• Testing and debugging. Conducting Unit tests and writing software scripts for automated testing, as well as fixing bugs and errors in the software.
• Creation of technical documentation. Writing and supporting software design documentation.

What skills, tools and programming languages should a backend developer have?

The development of innovative software solutions requires backend programmers to have flexibility and skills in working with a wide range of modern technologies - programming languages, frameworks and other tools. Here are the technologies that AVADA MEDIA specialists most often use in projects.

• Python. Python backend developers can be involved in the project to work with ML, AI, Big Data and create applications using the Django and Flask frameworks.
• PHP. PHP backend developers are primarily involved in the implementation of high-load websites and web applications using the Laravel or Symfony frameworks.
• Java. Java back-end developers create reliable solutions with microservice architecture and backward compatibility, including the Spring framework and the Hibernate library.
• JavaScript/TypeScript. Despite the fact that these languages are initially intended for the client side, they are also used for developing high-performance server applications on Node.js.
• C++ . Used in projects that require high performance and a low level of resource management, for example when creating financial systems, gamedev projects and system utilities where speed and efficiency are important.

Hard skills of a backend developer

A backend developer must also possess a number of technical skills. To develop server-side software, he needs:

• A clear understanding of the principles of operation of the server part of the software, client-server interaction and REST API.
• Skills in working with SQL and NoSQL databases, for example MySQL, PostgreSQL, MongoDB.
• Ability to work with cloud technologies such as AWS, Google Cloud and Azure.
• Skills in monitoring and checking systems for vulnerabilities, as well as implementing advanced SSL/TLS protocols to protect data.
• Ability to write efficient code and optimize database queries to improve software performance.
• Knowledge of version control systems, such as Git.
• Skills in designing and documenting APIs, as well as the ability to work with external APIs.
• Ability to conduct integration and unit testing of code.

How to properly check the competence of a backend developer

A qualified backend developer is needed to develop any modern software. But how can you make sure that the selected specialist has the necessary experience, knowledge and skills to successfully implement your project? In fact, this is not difficult - for this purpose, there are special methods for testing competencies in the IT market. Here are the most effective ones:

• Technical interview. Test candidates on their knowledge of the core technologies used in the project, asking questions about server architecture, database management, performance optimization, security, and code versioning.
• Test. Ask candidates to complete a hands-on assignment that involves developing an API, working with a database, or solving a specific problem. Or another option - provide them with a block of code for your project, ask them to analyze it and suggest improvements.
• Analysis of previous projects. Do some research and look at candidates' previous projects, evaluate the coding style and approaches used.
