Although we will be happy to explore new and challenging fields of activities and develop innovative projects with a unique combination of involved technologies!
We are working only with in-house developers and designers without subcontracting or outsourcing work to freelancers. We have two offices in Kyiv and Zaporizhzhya. They work in office on full-time positions.
This approach lets us to:
These are the main advantages and reasons for us to not subcontract development process and keep our team together.
In a blink of an eye)
There are several conditions that must be fulfilled before proceeding to the development of the project:
From our experience, it takes a week or so to settle these details with a client.
We always adhere to strict rules of development process organisation. Clear description of the project, detailed specifications, good planning from start to finish and transparent evaluation are principles that distinguish us from our competitors and guarantee development of high-quality product in compliance with the budget.
Delivery / Release
During the development process, we provide maximum security for both source code and user’s data.
Our projects are protected from:
Communication and Project management:
Generally, we are working in accordance with Agile methodology, but our PMs adapt management strategy to each project individually.
Correlation between methodology and project’s objectives:
In addition, Waterfall is useful if you have a limited budget for the project and can not allow additional changes to the project’s scope that can increase its cost.
Our project manager will be in touch with you all the time in order to provide all necessary information in the course of development and ensure that the end result meets your expectations. The frequency and the format of reporting will be agreed with the project manager during negotiations stage.
It’s up to you what communication channel to choose:
Usually, we assign time and day for regular meetings. All communication between developers are handled through task manager, where you can always see the progress of your project as a whole and each task separately.
Our PM will send you weekly reports with information on what’s done and next week plan. In addition, we make another skype call upon delivery of each milestone, during which we make presentation of results we’ve achieved.
Project Managers allow you to effectively communicate with the development team and they ensure that the final product meets your expectations.
PM is responsible for organization of the development process. They make sure that specialists understand your requirements and monitor the workflow, so that the project is ready on time and with the full set of features you have asked for.

Testing is held on each stage of development process. Starting from prototyping stage and finishing with post-release support of the project. Our testers are involved in the workflow of each project team. They are keeping an eye on the development process, monitor the product quality and compliance with customer requirements.
We perform testing in each browser from Big5 and on all popular mobile devices. We have a large “fleet” of devices including Apple Watch and various Android-powered wearables (see q. 23).
Our QA team provides detailed test documentation for the project’s layouts and user behavior rules (use cases). All bugs are carefully tracked in Redmine.
We perform four levels of software testing: Unit, System, Integration, and Acceptance testing.
The testing process is carried out on each stage of the development process:
We also perform automated testing which involves dedicated scripts that execute repetitive sequences of actions:
Automated testing is an advanced method which is required when testing complex projects. This type of testing can increase budget.
Here’s our blog post with detailed description of the testing process - Click Here
Upon completion of the development you will be given a week for product testing as a guarantee period. At the end of the week, our team will fix all the bugs that you’ve found within the project cost.
We handle the migration process to your server. It is included in the budget. Our admin will set up optimal environment for the product and advise you on each step of migration.
Mobile App delivery steps:
IMPORTANT: There is a registration fee and it may take a month to acquire approvement from Apple. This step should be performed by the actual owner of the app. Here’s a list of documents that are required in order to register Developer account - Click Here
Don’t worry! We’ll advise and guide you on each step of registration process.
All mobile apps require maintenance. Reasons are:
Because of these reasons, it is advised to hire a team to maintain your app. There are two possible solutions:
We provide a week of guarantee period. During this period, you can test the product and we’ll fix all identified bugs for free. We also thoroughly test the functionality of the product after each milestone and before final delivery. All additional works and upgrades are agreed separately.
Usually, we test applications on devices with latest OS version. In addition, our Project Manager can agree with you about additional devices for Quality Assurance.
Here’s the list of devices that we use for testing:
All cross-platform solutions result in significant loss of application performance. This is due to the fact that cross-platform solutions use web technologies that were initially designed to operate in web-environment and not as technologies for mobile apps.
Development of cross-platform solutions also results in disruption of OS guidelines developers and hence lowers the UI\UX quality. This is also due to the fact that users of each OS expect to see the elements of design that are peculiar for the specific OS. Cross-platform solutions can’t boast the same level of customization possibilities and only try to emulate native platforms.
A huge drawback of cross-platform solution is in its core limitation of OS compatibility. Cross-platform apps complicate the development at the point when they need to use the OS functions like camera, data storage, geolocation, etc. As a consequence, it requires additional time to code individual plug-ins for each OS.
Therefore, all types of mobile apps are better to develop using the same technologies mobile OS works with. This is applicable to SDK, frameworks and libraries that eventually should be compatible with the operating system.
Naturally, such approach enhances the total development time by about ⅔ but it also provides invaluable benefits:
Benefits of native solutions:
From technological perspective, the development of applications for tablets is not much different from mobile. The main difference and difficulty occurs during the design stage (screen size, screen orientation, layout).
The budget for software development and app design already includes tablet compatibility. Nevertheless, please specify the necessity of running your product on tablets, as there are nuances that we should take into account during design.
There are two variants of mobile apps adaptation for tablets:
We cannot provide you with 100% guarantee of Apple Store approvement, but we will do everything possible to make a successful release. We have extensive experience in approval of the apps that we have created.
Apple provides a list of the guidelines that make no exceptions for anyone. Here is the link. We are familiar with them and will discuss all risky moments that may affect the app approvement during the development of specifications. The decision to take those risks or to fix rough edges is always up to you.
Unfortunately, there is a risk that Apple Store moderators can ban the app even if you have complied with all their rules. Some of their reasons are quite absurd. For example: there are already many similar applications, or you are a direct competitor to Apple's native app, etc.
We’ll update your app upon delivery of new features. With the only exception: you provide us with all necessary content for the app.
How to update an App:
We have knowledge in development of software apps in various business domains including:
Here’s the list of frameworks, libraries, and tools that will let you successfully enter new markets and provide the additional value to your clients.

Web App Development
Our company strives to optimize time and costs expenses of our customers. Therefore, we are not only coding in clean PHP, but also use additional frameworks that contain a variety of ready-made solutions.
We use Yii2 - a PHP framework for development of large-scale Web applications. Yii2 advantages:
We have already accumulated a large code-base that will accelerate the development.
We think it's inefficient to use several different programming languages at a time. It must be acknowledged that the longer expert works with a certain set of tools - the faster he levels up.

Node.js is used for backend development when instant data exchange is required. The main advantage of Node.js over PHP is the ability of two-way communication between frontend and backend, while traditional RestFul API is one way street.
Frontend / Client End
Angular.js is a framework, that greatly accelerates the pace of development.
Backend for mobile applications is developed using the same technologies that are used for web projects:
In case of classic RESTfull API development , which does not require instant data exchange functionality, we use such technology stack:
In case we need to develop an app with instant data exchange features (chats, instant messages) we opt for:
However, upon client request, we can apply Google Firebase services as a backend for your mobile app, but only if such solution is compatible with app requirements.
Frontend technologies for iOS apps
Swift - It is a new programming language for MacOS, iOS, watchOS and tvOS that combines best features and principles from C and Objective-C. Swift is compatible with code written in Objective-C (the main language used by Apple in OS X), Cocoa framework and Xcode IDE.
Integrated Development Environment (IDE)
Xcode - It is a free, native application development environment for MacOS, iOS, watchOS. Xcode was created by Apple itself and contains a suite of software tools for development of native apps on Swift and Objective-C programming languages.
Architecture and Patterns
Software design patterns and architectural patterns are general solutions to solve core problems that occur during development of software. The architecture behind particular software solution can implement different patterns and approaches and depends on the initial requirements for the project. During mobile app development we use following patterns: MVC, MVP, VIPER.
CocoaPods - It is a dependency manager for Swift and Objective-C Cocoa projects. It has over 27 thousand of different libraries and is used in over 1.6 million apps. CocoaPods saves time for development by providing numerous libraries that help to scale apps and add new features by integrating ready-made solution.
Frontend technologies for Android
In most cases we code on Java (JDK 1.6 - 1.8). Optionally, in order to support CPU/GPU intensive operations, we use .so libraries or include c/cpp code. Among such intensive operations are graphics processing (e.g. Qualcomm Vuforia - augmented reality library), or non-graphic operations (Paypal SDK).
Integrated Development Environment (IDE)
Android Studio - Native IDE with all you need to develop and publish app to Google Play store. This is a free, cross-platform IDE that can be used in Windows / Mac / Linux.
Architecture and Patterns
Software design patterns and architectural patterns are general solutions to solve core problems that occur during software development. The architecture behind particular software solution can implement different patterns and approaches depending on the initial requirements for the project.
Gradle - It is an open-source build automation system that helps to inserts libraries while building applications. Almost all libraries can be included with just one string(!) in project config. Gradle enables easy transferring of the project to other development team and significantly cats overall time for development.
We use native technologies for the frontend development of Android and iOS apps.
You give an advance payment of 30% of the cost of the first milestone, and 70% upon completion of the first milestone (including testing the app’s functions embedded to the first milestone).
After that, 30% of the second milestone and 70% upon completion. Thus the payment is carried out until the final milestone.
Payment for the project is carried out for each milestone separately. The total project budget is divided by the number of planned milestones. At the beginning of each stage of development, you make advance payment - 30% of the cost of works that are scheduled in this milestone. After you confirm the works completed, you pay the remaining 70%.
If we’ve agreed to run the development in short sprints, then the interval between two payments could not exceed 2 weeks.
1. Bank transfer
You should sign a contract to make a payment. Here’s example of our contract:
Click to see example
Pros: you have a formal contract that protects your interests.
2. Pioneer payment system
You’ll be provided with a link through which you can make a payment. This is the least comfortable option for you because the transfer is carried directly to the credit card with no need to sign a formal contract.
3. Freelance platforms (Upwork, Pickcrew, etc.)
Cons: High Fees
Currencies we accept:
Any other currency you need. But it will take up to 2 weeks in order to open a dedicated bank account for the specific currency.
You are the only owner of the project and all its IP materials. We sign the NDA prior to the start of the development process. We can only ask to list your project in our portfolio as a reference of our work.
Here’s NONDISCLOSURE & CONFIDENTIALITY AGREEMENT we use - Click Here
You can also provide your own NDA.
We do not provide a free product maintenance. But we will be happy to carry out further works, add new features and maintain the system we’ve created.
