Development process

    Sites and mobile application for 'Spasibo from Sberbank'.

    Sites and mobile application for 'Spasibo from Sberbank'.

  • Create interactive prototypes of the future application (example)
  • We write a detailed technical task. We describe the most important: each screen of the application, backend, test scripts.
  • Having received a corporate style from the Client, we draw application layouts.
  • We program the back-end: the server part, which is responsible for the logic of the system.
  • We build applications for one or both platforms (iOS + Android).
  • We carry out internal testing with the customer, then we publish under the customer's account or ours.
Applications can be native or hybrid. Native is faster and can use all sensors and device capabilities.
Hybrid is faster and cheaper.

Mobile application: Virgin clients' personal account

  • Testing: Calabash, Android.test, JUnit, Appium
  • Automation, auto tests: Jenkins, Allure, Fastlane.

Production: development scheme, version control, autotests.

In the process of writing a terms of reference, we form the scheme of blocks of a site with dependencies: this allows programming in stages, as well as giving parallel tasks to programmers.

Using a version control system for a project, you can put several programmers at once, and their changes are easy to track. The same technology is used in further support site.

Project delivery: auto tests, load testing, PMI

We are writing a special document: a program and test methodology. On it is the delivery of the system. Also, when we submit a project, we write autotests (Selenium), then in Allure we look at visual reports on their passing.

Load testing is performed on the customer's server, we use Yandex.Tank and a number of services.


Extyl - rates in rubles

After delivery, we support the project using Jenkins for continuous integration - continuous update shipping, and GIT for version control.

Support and maintenance

After launch, we give an unlimited warranty on the application, within the devices that existed at the time the application was launched.
Improvements and adaptations for new devices are evaluated at a rate of $ 2,000 per hour.

Mobile application: video surveillance service for 'Er-Telecom' clients

What stand out

Creation of sites with ISO 9001: 2015 certification

Quality standards. In 2018 we confirmed the quality management standards: we are certified according to ISO 9001: 2015 (certificate) and ISO 27001: 2005 (information security management).

Transparency of development. Clients see Studio employees in our Intranet system and communicate with them directly. The agreements are fixed in the tasks, the information is not lost (unlike mail or phone).

When are we most effective?

  • Need a quick launch of an application to test a business hypothesis
  • the application is integrated with several systems at once, and not everyone has documentation
  • need a large advertising campaign and comprehensive service
  • for a number of works, you need not only 'hands', but also 'head', that is, analytics and consulting

Describe your task and we will evaluate it within 1-2 business days.
  • Average cost:
    $10 000 — $230 000
  • Development time:
    4 — 20 weeks
