Our software reengineering company offers the full spectrum of services from flawless code migrations to advanced architectural optimizations. All processes are aligned with your business growth.
The Corsac tool is AI-powered to help businesses safely rebuild and improve existing software without interrupting ongoing work. Intelligent re engineering framework automates analysis and decision-making and replaces traditional manual refactoring with modern automation tools, leaving key decisions and overall control by human experts. The result is a structured, predictable, and risk-free modernization
The solution from Corsac transforms legacy applications into advanced systems gradually. The platform examines existing applications as complete ecosystems, including source code, documentation, and development history.
It employs a Retrieval-Augmented Generation (RAG) architecture and a Multi-Agent Swarm to treat legacy code as a searchable dataset and turn legacy applications into a source of valuable knowledge.
The resulting strategy is predictable, risk-free, and perfectly aligned with business goals. The teams can enjoy a reliable modernization process that converts legacy software into scalable, efficient platforms through advanced application re engineering solutions.
Safer modernization process. Incremental updates minimize risks and prevent unexpected failures.
Business continuity. Teams can keep using systems while improvements are introduced.
Deeper understanding of existing platforms. AI surfaces hidden risks and dependencies blocking smooth expansion.
Faster engineering cycles. Automation reduces manual tasks, including analysis and planning.
Improved software quality. Modern architecture makes future maintenance and upgrades safer and less expensive.
We aren’t a full-stack agency. We’ve built our team, processes, and tech strategy specifically to tackle legacy issues and help mid-market players scale and innovate.
We integrate with your workflows, minimizing interference with your developers. While utilizing your Git, CI/CD, and tools, we operate independently, letting your team focus on their work.
Your aging system drains your business resources through slow hiring, security gaps, and delayed launches. We reduce these “dark tech debt” losses before they impact your revenue.
We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.
Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.
We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.
Legacy monoliths, old Perl/Java/Forms logic, and disconnected databases create massive barriers to AI adoption. AI needs clean data, stable interfaces, and consistent workflows – the opposite of what most legacy environments provide.
Application reengineering creates the stable architecture AI requires. It structurally rebuilds the system before AI adoption, erases modular boundaries, cleans APIs, normalizes data, and makes execution predictable.
Corsac team redesigns legacy architecture into modular API-first systems, integrating into your CI/CD. Every change, including building validated data pipelines and refactoring unstable logic, is incremental and testable.
With our software reengineering services, you receive an AI-compatible and stable system. Clean and reliable data for ML models, faster and safer integrations, cloud scalability, and measurable performance gains – all while keeping the smooth workflow.
We analyze the current state of your software – from checking code quality to compliance gaps to uncover flaws that may block modernization. We detect areas that should be preserved, replaced, or redesigned to set clear modernization goals.
Our software reengineering services start with assessing code hygiene, duplication, outdated patterns, and fragile logic. We analyze the reasons for complicated maintenance, repeating bugs, and define where refactoring would bring the most value.
Corsac team looks for issues such as tight coupling and architectural debt in your system’s structure, modules, integrations, and hosting. Our goal is a scalable application compatible with AI and ready for growth.
We review schemas, queries, storage design, and data flow to pinpoint legacy patterns that block accurate reporting, analytics, automation, and AI integration. You receive a clear vision of where application reengineering would bring a quick impact.
Our team highlights authentication, permissions, data handling, and encryption to identify weak points of legacy software. We uncover potential flaws from outdated code and compliance issues that make the software vulnerable to data breaches.
The solution from Corsac combines several coordinated modules. Each module covers a specific stage of the modernization process, guaranteeing reliability and control.
The platform inspects legacy applications to identify outdated libraries, security risks, and complex code areas, introducing visual dependency maps and technical debt reports. Using vector embeddings and Abstract Syntax Tree (AST) parsing, the system maps relationships between files, services, and business functions.
Result: a clear illustration of system structure and risks.
A structured roadmap is created by using dependency ordering and domain grouping. AI and automation tools organize tasks into development backlogs according to business capabilities. RAG mechanisms add company rules, such as required programming languages or architecture standards to guarantee compliance.
Result: meaningful modernization strategy, aligned with business priorities.
The modernization tool by Corsac involves multiple AI agents to identify current system behavior, generate modern services and interfaces, and check the equivalence between legacy and new outputs.
Equal behaviors of the old and new systems are ensured by automated testing.
Result: reliable application re engineering solutions with thorough test coverage and accurate documentation.
New components are implemented through intelligent traffic routing and canary deployment strategies. Data is synchronized to keep the old and new platforms operating in parallel.
Real-time monitoring controls latency and error rates. If they exceed the margins, automated rollback instantly restores the stable version.
Result: reliable transformation without operational risk.
We start with an inventory audit to assess your system both technically and from a business angle. Thanks to the reverse engineering approach, we restore missing or outdated documentation and get a better grasp of architectural logic.
We assess existing system concepts, taking into account your relevant business challenges and goals. Based on this, we redefine requirements to create a system that’s modular and adaptable to your evolving business needs.

We apply a modular architecture approach, modernizing modules one by one. All these ensure the integrity of ongoing operations and preservation of core functionality.
Without high-quality and on-time application reengineering, your system will be:
As a result, you’ll have extended spending and low competitiveness. There will be a higher risk of team burnout. Slow development, uncoordinated releases and inability to integrate new technologies will lead to missed market opportunities.
Sure! Our software reengineering company delivers not just system modernization. We offer ongoing support to ensure everything runs smoothly. After launch, we conduct hands-on training for your internal team if necessary, providing all the necessary documentation and tools for proper system maintenance.
No. Our software reengineering is license-free. It means that you have full system ownership, can scale and integrate new functionality without constraints. Moreover, such a solution is cost-effective. You’re free to spend budget on system innovations instead of struggling in vendor expenditures. You’ll be able to grow in step with strategic business needs.
First of all, we evaluate the scope of your legacy system and map out the desired outcome of modernization. We take into account the required integration, tech stack, and other necessary conditions. With your business goals in mind, we provide tailored calculations to define the most optimal budget.
