Hire a backend developer
BACKEND DEVELOPER
Backend represents the server side, or the hardware and software part, The emergence of this term came about because of the division of responsibility between the internal implementation and the external representation.
BACKEND AND ITS DEVELOPERS
For quite a long time, web development is a multi-level process, which is divided into two parts: frontend and backend. If we talk about the first of these components, it is considered the executable code in the browser, which is responsible for the display of web applications or sites, the correct operation of the elements on all kinds of gadgets, in other words, all that the client uses.
BACKEND DEVELOPER SALARIES
The minimum wage for backenders, which they quote on the freelance exchanges, is nine euros. But this pittance often confuses the potential employer, although he is well aware that for this money any worthwhile work will not be done, at most a consultation or only a plan will be made. Most recruiters estimate experience in years, but the IT specialists themselves proceed in this gradation from the knowledge and skills of the person and his or her independence. This is how this differentiation occurs:
Junior
Experience - 1-2 years. Able to handle the simplest tasks, often asking colleagues for help.
Middle
Specialist is more qualified. Experience - 3-5 years. Acquired almost all the skills of a backender.
Signor
Professional of the highest level. Experience - 6 or more years. Doesn't know any tasks he can't do.
Leed
Chief developer, captain of the team. In charge of managing and coordinating his charges.
WHAT IS A BACKEND
First of all, the backend is the code that runs on the server, from which the site or web application is loaded. In addition, it is the information bases of sites that are filled continuously, such as:
- news resources;
- forums;
- online stores.
Also the backend is the algorithm of any powerful online platform, for example:
- social media;
- trading exchanges;
- cloud storage.
The backend can consist of two levels: acting as its own frontend or as a lower level backend. If you take a WordPress blog, then its engine is considered the backend for readers. And the owners, administrators and content creators use it as a frontend, used as a convenient control panel, and as another backend - in the form of a database on MySQL, plugins and system files in RNR. Looking from afar, the backend is the server that hosts the web application or site, and their control panel is the frontend of the backend.
To summarize, the backend is a set of unobstructed processes that convey the final result through the frontend. In other words, anything that is hidden from the user's eyes and functions by itself is considered a backend. That is why they are looking for people who can do the backend development. They are also capable of developing an android application, a simple messenger and a speech recognition system.
WHAT BACKEND DEVELOPERS DO
These workers are engaged in the development and deployment of the server component of web resources. They create the basic logic and design the architecture of their projects, and then write the algorithm of their work. On how rationally everything will be done, depends on how secure, scalable and productive will be the server code.
Backend developers are confident in working with DBMS, which allows them to link code to a database and write query handlers for it without much difficulty. They know their way around any web server that receives and responds to requests from the frontend, so they can create an application that matches their capabilities and configuration.
The backend does not stay within the site or application itself. It should also include web services that communicate with other services, applications, and sites. Examples of these are:
- pingback;
- trackback;
- shering in social networks;
- online payment;
- pluggable reCAPTCHA.
Backend developers establish interaction with the programming interface of third-party applications, and can also develop their own, which will work with other resources.
Developers are directly responsible for performing requirements analysis and specification, programming, and drafting. However, it often happens that they are also engaged in testing, debugging, and code optimization. In large organizations, this work is performed by dedicated employees, while in small startups, the person who wrote the code is responsible for checking and refining it. But still, optimization and bug fixes are better handled by another team, which will have a fresh perspective on the problem.
LANGUAGES USED BY BACKEND DEVELOPERS
Each specific task is written in a suitable programming language. When developing the backend of web-sites, the most commonly used is RNR, and when creating applications the following languages are used:
- Rust;
- ASP.NET;
- Rust;
- C++;
- Ruby;
- Go;
- Python;
- Java.
Server-side programming languages on popular websites:
| Website | Server languages | DBMS |
|---|---|---|
| C, C++, Go, Java, Python | Bigtable, MariaDB | |
| Amazon | C++, Java, Perl | PostgreSQL, RDS, RDS Aurora |
| Wikipedia | PHP | MariaDB |
| C++, D, Erlang, Hack, Haskell, Java, PHP (HHVM), Python, XHP | Cassandra, HBase, MariaDB, MySQL | |
| YouTube | C, C++, Go, Java, Python | BigTable, MariaDB, Vitess |
| Yahoo | PHP | Cassandra, HBase, MongoDB, PostgreSQL |
| C++, Java, Ruby, Scala | MySQL |
Not all developers have a full command of these languages, but a talented specialist is able to quickly master a new language and quickly perform the work that requires its use. Partly in this plan come to the aid of universal and cloud development environments.
The development process is facilitated by auxiliary tools in the form of design and programming templates, frameworks and libraries for each of the languages. For this reason, each developer uses at least 1 set of tools, so that the project can be completed without violating deadlines.
SKILLS OF EXPERIENCED BACKEND DEVELOPERS
Developers dealing with relational DBMSs use structured query language or SQL. And those who are tired of this ubiquitous language have managed to master and now put into practice the method of object-relational mapping or ORM.
Information provided to the API is converted into the right format, and developers working to customize or maintain the API have mastered the extensible markup language, JSON data exchange format, the REST architectural style, and the SOAP protocol.
When working with web-servers can not do without specialized software, so every developer owns Nginx, Apache HTTP Server and Lighttpd. About them know in general inquisitive internet surfers who have dealt with bugs with codes 5xx on malformed sites and find out the cause of their occurrence.
If the task is to test the performance of a web application on local hardware, then based on the installed OS, backers use XAMPP, WAMP, MAMP or LAMP. In their work, they may encounter dedicated or virtualized servers, resulting in having to delve into Linux, hosting control panel, containerization and virtualization. However, it is difficult to call them true professionals in server administration. Nevertheless, they can make android applications with artificial intelligence and set up image recognition online.

It will not be easy to get backend developers with the necessary experience. And this is despite the fact that the labor market is full of representatives of this profession. But there are three main areas in which to find such people. These are freelance exchanges, HR-platforms and third-party teams. Each option will be discussed in detail below.
FRILANTS
To start the employer should start the search with service exchanges, among which can be named:
- Weblancer;
- Fiverr;
- Upwork;
- Freelancehunt;
- Freelance.Habr.
Select a suitable performer based on their portfolio and reviews of their previous clients. And when the choice is made, you should move on to discussing the future project, clearly stating the tasks and providing a detailed technical specification. To assign a detailed technical task and to indicate the deadline. If everything will be satisfactory, then the order is placed at the Exchanger, specifying all the conditions and requirements. Do not forget that you can immediately place an order for the backend, and then begin to process incoming proposals, using the same principle.
Pros:
- Freelancers who do not have the required experience, often use dumping on their services, which lowers the cost of the work in general in the market.
- The ability to look at the portfolio and reviews allows the right person.
Cons:
- It should be understood that the "discount" is already built into the price of expensive additional services, which is why the cost of basic services is so small.
- Freelancers are used to working with several clients at once, as a result of which their attention is dispersed, and there is no concentration on a particular project.
- Control over the person who took the job is difficult and he can easily disappear for a long time and not know that he will come back to work again.
- It often happens that the deadline is approaching, but the project still needs to be finalized. A freelancer finds a way out: he turns in an incomplete version, and asks for time to finish it all.
STAFF MEMBER
In this case, the employer goes to recruitment portals such as:
- SuperJob;
- Career.Habr;
- HH;
- Monster;
- Indeed.
It is important to pay attention to those backend developers who have solid experience in the IT sphere. After this, it is possible to conduct an interview with the applicant, the results of which will be obtained a certain impression of the future employee. In addition, it will be necessary to inform him about what his role in the company will be.
Pros:
- The employee is always close to the employer, making it possible to closely monitor his actions.
- The duties and rate of the working hours are stipulated at the stage of employment and do not change thereafter.
Cons:
- A person hired as a staff member must be formalized under an employment contract, which obliges the employer to pay insurance and taxes.
- The manager is faced with the fact that it is necessary to equip a workplace for the hired employee, provide him with technical means.
- There are times when an employee simply sits idle, not getting new tasks.
- Often hired employees are poached by other companies, promising a higher level of pay or the prospect of career advancement.
OUTSOURCING
Here we can talk about an option that embodies the previous two. If you apply to a team of backend developers working in a remote format, the employer will get professional and competent workers at its disposal. The functionality of these guys is so great that you can involve the team in parts, using only those who are needed at a certain stage of the project. In addition, all of the people in the team have already been tested for competence and have gained enough experience to act in a coordinated manner without interfering with each other.
Pros:
- There is a possibility of cooperation in the format of hourly pay.
- There is no need to constantly monitor the actions of workers, because their team leader does it.
- The entire development process is competently planned.
- Reporting is provided at each stage.
- The range of duties of the hired group of employees is legally supported by a formalized contract.
The only disadvantage is the cost. And even then, if we talk about freelancers, they will cost the employer cheaper, and full-time employees are much more expensive in comparison with a team of specialists.
