Legacy App Modernization
Improve your legacy system without compromising business continuity.
Relying on a legacy system is like driving a car with a hole in the tank – it will drain your time, money, and patience until you finally fix or replace it.
But the decision to upgrade is not always so easy. A complete rebuild seems risky, and a complex, outdated system too fragile to entrust to an outside vendor. But trust us, whatever you have, we've probably handled worse.
With our full-stack expertise, software delivery excellence framework, strong engineering standards, and robust project governance, we’ll upgrade your system seamlessly, without disrupting your business operations.
Working together, we'll audit your solution to determine the scope of changes that'll benefit you the most within your time and budget.
Encapsulate
Modifies the integration layer without changing the core logic.
Rehost
Migrates the system to a new infrastructure without altering code.
Replatform
Applies light code or configuration changes to adapt to a new platform.
Refactor
Restructures internal code without changing system behavior.
Rearchitect
Redesigns the app's architecture to meet your future needs better.
Rebuild
Completely rewrites the application from scratch.
Replace
Substitutes existing functionality with an entirely new system.
What problems we solve
Software agencies can promise anything – 'We'll do this, we'll do that, we'll bring you a star from the sky.' But the truth is, what drives you to look for a software partner are the real problems haunting your business. And what helps you choose the right vendor is their ability to actually solve them.
Slow Feature Delivery
Introducing new features is difficult and time-consuming due to the app's complexity.
Fear of Overhaul
Your legacy system is holding back business growth, but a complete overhaul seems too risky.
Scaling Issues
Your system lacks the scalability to handle increased demand, resulting in performance issues during peak usage.
Outdated Tech
The application you use depends on outdated technologies that are no longer supported, making maintenance increasingly difficult and expensive.
Poor Integration
Your software lacks integration with modern tools, platforms, and APIs, which limits your ability to innovate and automate.
Security Risks
Security vulnerabilities in your old codebase put your business and customer data at risk, but patching is slow and inconsistent.
How we deliver projects
Software development isn’t just about coding, it's about delivering business value. Knowing this, we base our work on the Delivery Excellence approach to create technologically advanced and business-effective apps.
Continuous Project Delivery
Short lead time for changes ALONG with world-class reliability, availability, and security
Consider this: “Delivered solution works in a production environment WHILE we can frequently deliver, deploy and release.”
Business-oriented Implementation Decisions
Ensuring technology and implementation decisions are geared toward most significant business impact
Consider this: “Delivered solution works in a production environment WHILE we can frequently deliver, deploy and release.”
Disciplined Project Governance
Maintaining strict oversight over budget, scope, timeline, and risks to ensure predictable outcomes
Consider this: “Delivered solution works in a production environment WHILE we can frequently deliver, deploy and release.”
Continuous Project Delivery
Mandatory automation of tests, deployment, and security controls
All code changes are delivered through fully automated pipelines. Secrets management, code analysis, and third-party dependency validation are built into the process.
Monitoring identifies issues before users do, preserving reliability trust and minimizing downtime
Built-in observability – through metrics, logs, and alerting – provides real-time insight into system behavior and enables proactive issue resolution.
Loosely coupled architecture increases scalability and enables faster product adaptability
Modular systems with minimal dependencies between components allow for independent development, testing, and scaling.
Business-oriented Implementation Decisions
Decisions are documented and versioned to ensure long-term clarity
Key decisions across engineering and product are documented and versioned using practices like Architecture Decision Records (ADRs) and Product Decision Records (PDRs).
Product requirements are based on continuous, validated discovery
Continuous discovery of user needs, market opportunities, and business goals throughout the product lifecycle to define a solution truly worth building and constantly adapt to change.
Legal requirements and industry standards are enforced at all times
Security, risk, access control, and data handling processes are aligned with major legal and industry standards – including ISO 27001, TISAX and GDPR.
Disciplined Project Governance
Disciplined delivery governance ensures budget, timeline, and scope stay under control at all times
PRINCE2 Agile framework blends structured control with agile flexibility. It provides high-velocity delivery while maintaining budget, scope, timeline, and risks under control.
Risks are continuously assessed and managed throughout delivery
Scope evolves. Priorities shift. We handle it with proactive risk & change management – balancing business agility with delivery control to avoid delays, scope creep, or budget overrun.
Transparent communication with clear cadence and discipline
We keep you informed with clear status reports, direct access to engineers, milestone-driven reviews, and daily standups.
What our Clients say about us
Probably any company would benefit from working with Brainhub, but if you have more complex issues like dealing with technical debt or have some big challenges you want to tackle but don’t really know how, I would definitely think of Brainhub for that.
When we contacted Brainhub, we basically wanted to have the best people on board within the shortest time. So Brainhub was the best partner for us. We don't treat Brainhub's people as contractors but as other team members.
They’ve had a significant impact on how we build our applications by suggesting proactive changes, which we consider valuable.
I haven't found more skilled resources than Brainhub's team. Every Brainhub teammate I've worked with has greatly contributed to our project. I've never worked with a teammate from Brainhub that doesn't meet our performance requirements.
Brainhub is a boutique firm and skilled organization. The team has a rigorous hiring process, and they're very selective.
