End-to-End Software Reengineering Services to Transform Legacy Systems

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.

modernization-solution

Legacy Code Refactoring

We carefully rebuild your current codebase without affecting its output. You’ll end up with an easy-to-maintain, efficient, and scalable system without tech debt.

Architecture Redesign

We address outdated architecture design to enhance functionality, cut maintenance costs, and speed up the development process. As a result, your software becomes scalable and highly-performant.

Technology Stack Upgrade

We assess your tech setup to identify gaps and apply the best approach to meet your business needs – no matter whether you need to adopt new platforms, integrate the latest tools or migrate to an alternative tech stack.

UI/UX Modernization

Legacy apps usually suffer from clunky, non-intuitive UI/UX. We refresh your interfaces, streamlining user satisfaction, engagement, and overall product usability. If required, we build a new design system or refine your current one to unify all elements and ensure a cohesive look.

Database Reengineering

We revamp your current database by improving schema design and query efficiency, data normalizing, and migration. We help achieve data consistency, seamless data management, and better system performance.

System Integration & API Enablement

We ensure smooth third-party connectivity, AI/ML integrations, and advanced analytics to uplevel your operations. As a result, you can process large datasets and build evidence-based forecasts.

We help you get maximum value from external services by optimizing expenditures and suggesting budget-friendly alternatives.

Why Choose Corsac Technologies?

Square icon

Modernization is our core specialization

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.

Square icon

Integration vs. Disruption

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.

Square icon

Identification of hidden expenditures

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.

Square icon

AI & Emerging Tech Enablement

We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.

Square icon

Fighting Tech Stagnation

Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.

Square icon

Respect for Existing Architecture and Leadership

We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.

Reengineering for AI Adoption

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.

Reengineering Essence

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.

What Corsac Does

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.

What You Get

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.

Software Reengineering Audit: Find Weak Points Before Modernization

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.

Code Quality Audit

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.

Architecture & Infrastructure Audit

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.

Performance & Database Audit

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.

Security & Compliance Audit

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.

Streamlined Software Reengineering Backed by a Full-Cycle Approach

Discovery & Technical Assessment

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.

Strategic Reengineering Planning

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.

    Frequently Asked Questions

    Absolutely. Our reengineering services are based on deep analysis of your current business logic, needs, and goals. We plan each step thoroughly and provide upgrades gradually. 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:

    • hard to maintain and add new features
    • vulnerable in terms of cybersecurity
    • unscalable
    • slow and with recurring failures
    • cost-inefficient

    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.
