Technical Debt & Legacy Modernisation

Fix, modernise, and secure legacy web applications — even when your team can't help

Get Started Today

When Your Development Team Can't Help, We Can

Your critical business application runs on outdated code. The developer who built it left years ago. Your current team doesn't know the legacy technology. Security vulnerabilities are mounting. Sound familiar?

We specialise in understanding and fixing legacy web applications and custom software. If your application runs in a web browser and you have access to the code files, we can help. We don't just patch problems — we modernise, secure, and future-proof your critical business systems.

🔧

Legacy Code Remediation

Fix bugs in abandoned codebases, resolve years-old technical debt, and maintain functionality while modernising. Deep code analysis and remediation expertise.

âŦ†ī¸

Platform Modernisation

Upgrade outdated systems to current, secure versions. Modernise your application platform, update dependencies, and fix security vulnerabilities while maintaining full functionality.

🔗

System Integration

Connect legacy systems with modern platforms via APIs. Bridge old and new systems seamlessly, enabling data flow and workflow integration.

đŸ›Ąī¸

Security Uplift

Modernise security standards, patch vulnerabilities, update authentication systems, and ensure compliance with current security requirements.

📋

Knowledge Transfer

Document legacy systems, create technical documentation, and transfer knowledge to your team. No more "bus factor" risks.

⚡

Minimal Disruption

Modernise without rewriting from scratch. Maintain business continuity while upgrading your technology stack and security posture.

What We Can Modernise

We fix and modernise web-based business applications and custom software. Here's what we can and cannot help with:

✅ What We Can Fix & Modernise

  • Web-based business applications (accessed via browser)
  • Internal tools and systems built for your business
  • Custom software developed specifically for your company
  • Legacy web systems that run on your servers
  • Outdated applications that need security upgrades
  • Systems where the original developer has left
  • Applications with bugs no one can fix
  • Systems that need to integrate with modern platforms
  • Any web application where you have access to the code files
Simple test: If your application runs in a web browser and you can access the code files on your server, we can likely help modernise it.

❌ What We Don't Work With

  • Desktop software installed on computers (like .exe files)
  • Commercial software you purchased (without source code access)
  • Third-party applications you don't own the code for
  • Software where the code files aren't accessible
Good news: Even if we can't modify proprietary software, we can help integrate your web applications with any system using APIs and webhooks.

Technologies We Modernise

We work with a wide range of web application technologies. Here are the most common platforms we modernise:

PHP 5.x → 8.x upgrades

Python Web Applications

Modernise Python-based web applications, including Django and Flask frameworks. Update dependencies, improve security, and enhance performance.

Django, Flask, Legacy Python

Node.js Applications

Upgrade Node.js applications to current versions, update npm packages, modernise security practices, and improve application performance.

Node.js, Express, npm

Microsoft .NET Applications

Modernise ASP.NET web applications, upgrade frameworks, improve security and performance, and ensure compatibility with current Microsoft technologies.

ASP.NET, .NET Framework

Java Web Applications

Upgrade Java-based web applications, modernise frameworks like Spring, improve security and scalability, and ensure compatibility with current Java versions.

Java, Spring, JSP

Don't see your technology listed? If your application runs in a web browser and you have access to the code files, we can likely help. Contact us to discuss your specific technology stack.

Common Scenarios We Solve

These are the types of challenges we help businesses overcome:

🔴 Abandoned Codebase

Your critical web application was built by a developer who left years ago. No one on your current team knows the technology stack. Bugs are mounting, and you can't find help.

âŦ†ī¸ Platform Upgrade Required

Your web application runs on outdated technology, but your development team specialises in different technologies. You need to upgrade for security and compatibility, but no one on your team can help.

🐛 Long-Standing Bugs

Your legacy web application has bugs that have existed for years. Your team has tried to fix them but doesn't understand the legacy codebase. The bugs are impacting business operations.

🔒 Security Vulnerabilities

Security audits have identified critical vulnerabilities in your legacy web application. You need to modernise security standards, but your team lacks expertise in the legacy technology.

🔗 Integration Challenges

Your legacy web application needs to integrate with modern cloud services or other systems, but the codebase is outdated and your team doesn't know how to build the integration.

📋 Technical Debt Accumulation

Years of technical debt are blocking new development. Your team wants to build new features, but the legacy codebase is too complex and risky to modify without expert help.
