Our app development services

Combining tech expertise and industry-specific knowledge accumulated for over 20 years in the IT industry, Itransition develops custom software for medium-sized businesses and enterprises. Our offering includes on-request application development services, covering our customers’ multiple business needs and technological objectives.

Custom application development

Itransition builds custom solutions from scratch, ensuring their seamless integration with existing environments and systems.

Platform-based product customization

With profound knowledge of tech platforms and components, we create software with an optimal set of out-of-the-box and custom features.

Legacy application redesign

We redesign outdated systems, refactor their code, migrate legacy apps to newer platforms, and review their architectures to give them a new lease life.

Full-cycle custom application development

Itransition develops software products from the ground up as well as takes up development at any stage of the software lifecycle. We help our customers generate detailed requirements that we turn into real applications. We also assist companies in the post-deployment period and provide long-term maintenance and support services for the implemented solutions.

Requirements gathering

Itransition’s business analysts possess extensive technological and domain-specific knowledge to collect, analyze, assess and structure our customers’ functional and nonfunctional requirements for their applications. This stage is followed with drawing up a detailed solution development roadmap.


Based on the deliverables from the business analysis phase, our team builds wireframes and prototypes to assess software feasibility and get the customer’s early feedback. In case our architects detect technical bottlenecks, we offer alternative solutions to address the initial requirements.

Product design

Our team of UI and UX designers translates the collected requirements and prototypes into product design. We set up the product usage scenarios, navigation, and interactive components. We also define user personas and their paths to deliver an intuitive design.

Custom app development

Itransition develops custom web and mobile applications while prioritizing their easy management, integration and scalability. We couple our development activities with continuous testing to check the solution’s performance and behavior, as well as assess the functional health of all software components.

Maintenance and support

We offer three levels of support for applications developed either by Itransition or by a third-party vendor. We can solve a variety of challenges: application upgrades and functional improvements, performance monitoring and security assessment, application migration and integration.
