Legacy Code Refactoring & Debugging Services UK

Q: Do you work with code written by overseas freelancers?

Yes, frequently. A large part of our business is 'Legacy Rescue'—taking over undocumented, messy, or incomplete codebases from previous developers and turning them into stable, enterprise-grade assets.

We rescue messy code and stabilize failing platforms. Based in Swansea, our senior engineers transform technical debt into clean, maintainable, and highly scalable architecture.

Does Your App Have These Symptoms?

If you recognize any of these, your codebase has accumulated dangerous technical debt. We specialize in diagnosing and fixing exactly these issues without taking your app offline.

🚨 Performance & Reliability

☐ Pages take 5+ seconds to load
☐ Database queries are slow (N+1 problems)
☐ Memory leaks causing random production crashes
☐ CPU usage is consistently high resulting in massive AWS bills
☐ Silent failures and impossible-to-debug errors

📦 Maintainability Nightmares

☐ Adding simple features takes months
☐ Massive, 1000+ line undocumented code files
☐ Outdated, unpatched dependencies (Security Risk)
☐ Zero automated tests (Developers are afraid to touch it)
☐ The original developers have disappeared

Checked 3+ boxes? Your codebase needs a surgical intervention. The longer you wait, the more expensive it becomes.

Our Auditing & Refactoring Process

A systematic approach to modernizing your application with zero downtime.

1

Paid Deep Audit (1-2 weeks)

We don't make assumptions. We read your code, run profilers, analyze logs, and understand exactly what's broken before we write a single line of code.

✓ Performance & Memory profiling
✓ Security vulnerability scanning
✓ Database architecture analysis

Deliverable: A comprehensive technical roadmap and exact fixed-price quote for Phase 2.

2

Strategic Refactoring (4-12 weeks)

We execute the roadmap, tackling the biggest wins first—the issues that directly impact your users, security, or AWS billing.

✓ Fix critical security vulnerabilities
✓ Optimize slow queries & implement caching
✓ Add comprehensive test coverage (CI/CD)

Deliverable: A fast, secure, and maintainable codebase deployed with zero downtime.

💰

Lower Cloud Bills

Optimized database queries mean fewer servers needed, slashing your AWS costs.

📈

2-3x Faster Development

Adding new features becomes rapid and safe when the underlying architecture is clean.

Frequently Asked Questions

Will my app go offline during refactoring?

No. We use blue-green deployment strategies and zero-downtime pipelines. We refactor and test in mirrored staging environments before shifting traffic, ensuring your users never notice a single second of downtime.
