With our software reengineering services, VST can optimize and update the software code of your legacy applications, port your systems to a modern stack of technologies, and migrate your data or legacy servers to modern platforms.

Our software reengineering and migration capabilities include:

  • Migration from obsolete technologies to modern ones. Our expertise in creating software architecture ensures proper usage of technologies and tools to leverage the business value of your legacy application.
  • Reverse engineering of the solution; it is especially important for the software, which doesn't have actual documentation.
  • To ensure a smooth transition, we offer 24/7 post-migration support, re-documentation of the migrated systems, and extensive consulting services.
  • Our software reengineering service can breathe new life into business-critical systems, developed many years ago, allows you to benefit from the better scalability, enjoy increased performance, and focus on important business tasks with fewer faults and downtimes.

To address these and other challenges, we utilize our comprehensive competencies in software research and development, application development, and application testing. We have significant experience in software reengineering and migration, which enables us to meet the most stringent requirements of our customers.

  • Obsolete technologies create difficulties with application environment and integration.
  • Lack of competent specialists on the market.
  • Difficulties with developers' motivation – everybody wants to work with cutting-edge technologies.
  • Decreased solution competitiveness and attractiveness for the end users.
  • Lack of up-to-date application documentation

Our Approach: from RFP to Support


We collect your ideas and requirements and convert them into solution concepts, objectives, and new opportunities for your business.


We study your domain, business priorities, and project scope and assess them against relevant technologies, possible technical constraints, and implementation practicalities.


We design the system: define the architecture, modules, interfaces, and data for your system, assign the team and decide on the development life cycle and methodology.


We develop and complete your project deliverables. Depending on your requirements and timeframe, we use a range of proven approaches and methodologies.

Development Approaches and Methodologies

Iterative or agile approach - Scrum and Kanban methodologies.
Use-case driven, architecture-centric, iterative, and incremental approach - RUP methodology.
Breaking down project activities into linear sequential phases - Waterfall methodology.


We employ the proper tech stack to develop all solution components and stabilize the deployment.


We ensure that your system is fully functional, always performs as expected, and scales along with your needs.

Tech Stack & Verified Expertise

Web apps

Our web development team relies on the latest, most reliable technologies and frameworks to ensure solid, uninterrupted performance for your product.

18+ years in custom software development services. Our experienced business analysts, architects and developers have years of hands-on experience in cross-domain areas.

Flexibility and Transparency

We offer our clients a full range of engagement models to suit their business needs and project objectives.

Mature Process

We mitigate risks by driving complex long-term projects in line with proven methodologies, including Agile (SCRUM) and RAD, as well as “classical” software development processes like RUP.

Quality Control

Our QA department participates in the development process from the earliest stages to ensure comprehensive testing coverage and accurate quality assessment.

Post-Release Maintenance and Support

We understand how important it is for our customers to deliver useful and convenient software to the market to stay competitive and profitable.

We address these challenges through special maintenance and support services aimed to fix functional inconsistencies, patch vulnerabilities, and improve system's performance. A well-thought QA strategy along with post-release maintenance and support helps mitigate risks associated with the new software launch.

We assess your future solution enhancement needs and suggest a relevant plan: incorporate user feedback, ensure your solution against failure or malfunction caused by operating system upgrades, and reinforce your app's functional features.
