At Fayrix we realize that any organization may encounter problems of choosing the wrong technology or development approach. These issues may appear tactical, but can also have wide ranging impact on the successful and continuing operations of the overall business. So before starting any kind of project we carefully investigate your company's niche features, compare already implemented solutions and offer a stack of technologies that are most suitable for your specific situation.

What we can offer

For enterprises

Enterprise software has its own specific set of requirements. The architecture should be scalable, but cost-effective, safe, but user-friendly, and, above all, it should provide high-quality user services that produce results. Fayrix high quality engineers will help your company to build powerful enterprise software.

For tech companies

Development of high-tech solutions requires highly qualified specialists with the necessary niche work experience.
Sometimes tech companies are facing with the lack of experts on location. Fayrix team is ready to scale your IT department and bring innovations, relying on the most relevant technologies.

For startups

Startup companies may face many challenges during early development. Wide range of technologies can help them with a fast start and a successful market entry. Besides the use of cross-platform technologies can significantly reduce the MVP release time.

Back-end development

The back end of a website consists of a server, an application, and a database. A back-end developer builds and maintains the technology that powers those components which, together, enable the user-facing side of the website to even exist in the first place. In order to make the server, application, and database communicate with each other, back-end devs use server-side languages like PHP, Ruby, Python, Java, and .Net to build an application, and tools like MySQL, Oracle, and SQL Server to find, save, or change data and serve it back to the user in front-end code. At Fayrix we have a great experience in back-end development that you can check - from developing mobile platforms to building an advanced solution to manage the whole cycle of education process at schools.

PHP

Despite the fact that PHP was developed in 1994, it is still the most common language for server-side development. PHP is open source, and all features and updates are free to use. Today there are many popular projects based on PHP like Facebook or WordPress. Since it was designed specifically for the web, developers need less time to create websites with dynamic features.

Can be used for:
- Web applications. Is great and effective solution for the e-commerce platforms. For example, WooCommerce was also fully developed by PHP. It runs nearly half of all online purchases in the world.
- CMS development.
- Social networks.

Pros
- PHP development provides many opportunities. With the proper level of knowledge, using the template engine you can create not only scripts for web applications, but also full-fledged programs.
- Cross-platform development. PHP can be run on any operating system, including unixoids.
- Free distribution. Perhaps PHP was not so popular for creating web-applications, if it were not free, like most tools for working with it. Analogs, which basically can do the same job, usually cost more.
- Variety of training materials. That is why, if something doesn't work out for you, you can always look into the search engine: your problem, most likely, has already been encountered by someone.
- Continuous development. The fact that so much is known about the template engine today means only one thing: they will cope with the shortcomings, sooner or later.
Cons
- Narrow specialization. If you have learned PHP development, then probably you've got only one way - to the web. PHP is tuned for programming for the Internet.
- Safety. The widespread use played a cruel joke: holes in PHP appears faster than developers manage to close them. It is difficult to predict everything.
- Code discrepancies. PHP is full of various residues from different development languages. And all of them can even be concentrated in one expression of the code.
Summary
- Low development cost.
- Wide choice of candidates.

Java

Java is a programming language and computing platform that was first released in 1995. Java is fast, highly protected, and reliable. Despite the growing popularity of Go and Python, Java has remained at the top of the list for more than a decade. And its everywhere - from laptops to data centers, from game consoles to supercomputers used for scientific research, etc.

Can be used for:
- Android applications. Despite the active growth of Kotlin, Java is still the de facto main language of Android applications. Thus, all Java developers can very easily become Android programmers. Although Android uses the Android SDK instead of the JDK, however, the code is written in Java.
- Software products. Among other important things, Java was used to create Eclipse, OpenOffice, Gmail, Atlassian and others.
- Financial programs. Java is one of the most sought-after languages in financial industry. It is used to create reliable, fast and simple websites both on the server side and on the client side.
- POS. Many companies are using Java to create PoS systems, since their creation usually requires cross-platform and an extensive staff of specialists.
- Trading systems. One of the popular bank management program for front-end and feedback Murex was also written in Java.
- Big Data Software. What is more Hadoop was written in Java. Scala, Kafka and Spark use the JVM. In addition, Java provides access to many proven libraries, debugging and monitoring tools.

Pros
- The highest portability of programs among all programming languages.
- Powerful standard libraries.
- Built-in network support (both local and Internet / Intranet).
- Powerful Big Data Tools.
Cons
- Low performance (in comparison with other languages), increased requirements to RAM volume.
- Average entry threshold — large volume of standard libraries and technologies complicates language learning process.
- Constant development of the language causes the presence of both obsolete and new tools that have the same functional purpose — a large number of legacy code.
Summary
- Average development cost.
- Wide choice of candidates.

Node.js

A relatively young technology that is gaining popularity recently. Node.js is based on V8 JavaScript engine used by Google Chrome. This allows to achieve high performance without the use of multithreading. Having a single language on the stack breaks down communication barriers in a team and makes software development outsourcing easier to maintain.

Can be used for:
- Developing programs for the web, as well as for Linux, OS X and Windows.
- API formation, using NodeJS built-in libraries.
- Payment systems like PayPal that allows you to work with payments, without sharing financial information. Node helped to establish a connection between the browser and the server due to the fact that both sides are written in the same language.
- Web and mobile applications.

Pros
- It can handle multiple requests simultaneously.
- One language on the client and server. If a programmer has improved skills in JavaScript, it will be easier for him to learn the "add-on" than radically different technology.
- Speed. Creating a working prototype to cope with the load does not take much time.
- JavaScript syntax. Yes, you will have to learn new tools, but there will be many familiar things. This provides relative simplicity and accessibility.
Cons
- Callback-hell.
- Not suitable for multithreading.
- Bad for computing.
- A large number of third-party packages.
Summary
- Development cost - above average.
- Wide choice of candidates.

The front end of a website is the part that users interact with. Everything that you see when you're navigating around the Internet, from fonts and colours to dropdown menus and sliders, is a combo of HTML, CSS, and JavaScript being controlled by your computer's browser. Front-end developers are responsible for a website's user-facing code and the architecture of its immersive user experiences. What is more, front-end devs need to be familiar with frameworks like Bootstrap, Foundation, Backbone, AngularJS, and EmberJS, which ensure great-looking content no matter the device, and libraries like jQuery and LESS, which package code into a more useful, time-saving form.

React

React - is JavaScript library, it's source code was opened by Facebook in 2013. This framework is great for creating huge web applications where data can change on a regular basis.
