What Kind of Software Development Approach Are You Interested In?

Using our solutions

Modular approach based on our existing architecture cores to reduce time and costs of software development.

Development from scratch

Full-scale development process with every element designed and built from zero, including the core, etc.

Core Services

Mobile App Consulting

We will analyze your business, goals, needs, existing deliverables, and suggest the optimal approach to custom software development.

Custom Software Development

Custom projects tailored to unique needs of an organization. Based on the business goals and needs, we will combine development from scratch and integrating third-party API.

Mobile App Software Design

Based on your business needs and project’s state, our experts can cover UX/UI Design, Software Architecture Design, Software Prototyping, and more.

Quality Assurance and Maintenance

Our team will take over the project and ensure that it, through testing and monitoring, offers seamless experience to the customers.

Related Services

Regardless of the stage of your project, we can take over and complete the development of your software. We offer a comprehensive list of services that can be a part of one process, or be performed standalone using the pre-existing deliverables that you received from other teams.

Project Discovery

This is an important phase that results in the creation of a project charter, which outlines the project goals, objectives, and scope, as well as the deliverables, timelines, and budget

UX and UI Design

We build User Experience (UX) from scratch, as well as create User Interfaces (UI) that meet standards for software of various scopes and complexities

Software Prototyping

Software product prototype is a necessary, time-tested, and efficient step for a quicker and more cost-effective software product built from scratch

Minimum Viable Product (MVP)

This is a product version with sufficient features to validate business assumptions and market feasibility quickly and to test whether it meets the end-user needs

Software Development from Scratch

We cover end-to-end SDLC scope, from requirements gathering to design, development, testing, deployment, and maintenance. Ideally, it starts from Discovery Phase, moving through PoC/PoT, MVP to Full-Scale Product

Software Components Development

We develop specialized system services or modules within our expertise for existing platforms. Our engineers work closely with other teams to ensure that our item fully integrates with the overall platform

Legacy Software Modernization

We rebuild outdated software to meet modern technology, necessary security, compliances, performance standards, and user requirements, including data migration from the old system to the new one

Software Maintenance

We provide corrective, preventive, risk-and condition-based post-release maintenance via an ongoing process of changing, modifying, improving, fixing, optimizing, and updating the software to keep up with end user's needs

Proof of Concept (PoC, PoT)

PoC or PoT is the first step when facing technological challenges. The goal is to prove the possibility of technical implementation and viability of the concept as a whole

Software Documentation

We audit your software and existing docs and write up-to-date system descriptions, design decisions, architecture descriptions, technical help guides, user manuals, tutorials, or user guides following ISO / IEC / IEEE Standards if required

Independent Software Audit

If you already have software at the release stage (α or β), we are experienced in independent pre-production software audits and identifying potential issues and risks that may impact the project's success post-release

Software Issues Resolution

If your software has functional, performance, security, or compliance issues, we identify and resolve them via logic reworking, code refactoring continuing maintenance and ongoing support

Our Approach to Mobile Application  Development and Support

Each step can be the start of our collaboration, based on the state of your idea, project, and documentation. We work with third-party designs, code, and software, helping our clients see the project through.

Where Do We Go From Here?

Learning About Your Needs

We will provide detailed breakdowns and specific course of action based on your timeline, budget, selected technology, and much more.

Documentation & NDA

You will be able to share any existing deliverables such as documents, designs, and code, with the assurance of an NDA to protect your intellectual assets.

Planning and estimates

Our analysis will cover all available data, resulting in a thorough functional decomposition and an accurate, detailed estimation for your project.

Financial Proposal

We’ll prepare Basic, Recommended, and Advanced cost offers for you to choose from, providing options that scale with your business needs and budget considerations.

Kick-off

Post-contract, you'll be introduced to your project's dedicated team. We will start the work, ensuring complete transparency and involving you throughout the process.

What Are The Benefits Of Native and Cross-Platform/Hybrid Mobile Apps?

Native Mobile Apps

Native mobile apps are designed and developed specifically for a particular mobile platform, such as iOS or Android, using the platform-specific programming language, tools, and libraries. Here are some reasons why native mobile apps can be a great choice:

Better Performance

Greater Security

Offline Functionality

Unlimited Access to Device Features

Better Integration with the Operating System

Better User Experience

Cross Platform and Hybrid Mobile Apps

Hybrid mobile applications combine elements of both native mobile apps and web apps, and are developed using web technologies such as HTML, CSS, and JavaScript, and then wrapped in a native container that can be deployed to different mobile platforms. Here are some reasons why hybrid mobile applications can be a good choice:

Cross-Platform Development

Faster Development Time

Cheaper Maintenance

Lower Development Costs

Components We Cover

Mobile Application

Server infrastructure

Back-end

Database

API

3rd-party services

Technologies we use

We conduct technical research considering requirements, business goals, scaling plan, and more. We compile a comparative table of optimal technologies for your specific software product. Based on the recommendations of our team, we advise on the most suitable technology stack, taking into account all the aspects mentioned above.
