Web App Development: Ruby on Rails, ReactJS, NodeJS

Front-end & back-end

We take care of the whole development process. From communication and database issues to interactions and visual elements.

PRODUCT MAINTenANCE

Our code is clear which makes editing easier. Thanks to this developers can quickly add new features and fix potential bugs.

Safety

In product versions of our apps we never log data to user console. We also obfuscate code in order to hide data from the third parties.

User Experience

Good design makes using our apps a pleasure. That’s because we focus on the intuitive navigation and implement solutions users know well.

QA tests

Every time we make changes, we test if all the features work properly. This approach lets us quickly find errors and constantly refine the products.

Agile approach

We develop our projects in the iterative process. After each stage we evaluate a product. It allows us to control its quality and solve the problems faster.

Our technologies

What do we specialize in?

Back-end

To storage data, process and handle it, we use Ruby on Rails, Node.js, and PHP. This selection of technologies gives us an access to many ready-to-use components. It also accelerates web development process and lets us work efficiently even when the project is complex.

Front-end

React.js is a library we choose to build interfaces. This means creating views or interactions and communicating with database. React.js makes it possible to use selected components multiple times, and thus the development is easier. It’s also more productive. As a result, users get a fast, dynamic app that builds a better image of your business.

Responsive Web Design

Our apps adjust to the size of a browser’s window, so they look equally good on different models of smartphones, tablets, and laptops. RWD apps allow users to take full advantage of the features, regardless of the display size.

budget for the development and maintenance is limited,
your users are usually reluctant to download mobile apps,
you don’t plan to offer a lot of features,
access in the offline mode isn’t necessary,
due to the nature of your services, users don’t need them often,
access to native components of the mobile device (e.g., camera or music player) isn’t essential.
