Our Services

Frontend Development

Our frontend developers constantly imagine theirself as a user and create pages with an intuitive interface of a software, application or website. The goal of our front end developers is to create clear, easy, fast pages and interfaces that will make people understand and care about the information, by putting it in context, expose its legitimacy or lack thereof, and reveal their implicit or explicit interconnection. We consider that front-end is not just a pretty face, it’s the friendly, forward-looking interface of web development.

Backend Development

We call back-end code the brain of any app out there. The back-end development is a part of the application that is never visible to the user. It is built with use of server-side language and database. The developer builds an application (using server-side code like PHP, Ruby, .Net etc.) which connects with a database (using MySQL, SQL, Access etc.) to look up, save or change data and return it back to the user in form of front-end code. This complicated structure helps to look for things, shop, interact socially and more in the modern world of the internet.

Design and Architecture

Our companies offers services for interface design and prototyping. Constant's design team has experience and education in both services combined with good visual design and usability. The interface design services are usually integrated as a part of the software development team. The technologies used for interface design include: Web 2.0, Flash.

Mobile Development

Mobile application development by which application software is developed for handheld devices, such as personal digital assistants, enterprise digital assistants or mobile phones. These applications can be pre-installed on phones during manufacturing platforms, or delivered as web applications using server-side or client-side processing (e.g. JavaScript) to provide an "application-like" experience within a Web browser. The majority of mobile application development efforts will focus on creating browser-based applications that are device-agnostic. Browser-based applications are simply websites that are built for mobile browsers. Such sites are built to load quickly over a cellular network and have finger-friendly navigation.

Native Applications

A native application (native app) is an application program that has been developed for use on a particular platform or device. Because of this, native app has the ability to use device-specific hardware and software, meaning that native apps can take advantage of the latest technology available on mobile devices such as a global positioning system (GPS) and camera. This can be construed as an advantage for native apps over Web apps or mobile cloud apps.

QA and Testing

Quality Assurance (QA) is a way of preventing mistakes or defects in manufactured products and avoiding problems when delivering solutions or services to customers. QA is also applied to software to verify that features and functionality meet business objectives, and that code is relatively bug free prior to shipping or releasing new software products and versions.
Constant testing services incude: test planning, automated testing, usability testing, stress testing. The testing services can be used as a separate service or intergrated as a part of the programming process.
