Front-end & back-end
What do we specialize in?
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.
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.
Web app is a good idea when...
- 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.
