Legacy Code Discovery

Meet Your
Code Archaeologist AI Agent

Old code is expensive to keep and scary to change. The Code Archaeologist maps your entire codebase, finds the dead weight, and builds a safe path forward - no guesswork, no risky rewrites.

The Infrastructure Crisis:
Legacy Code Debt Is Draining Your Budget.

Your application works - mostly. But every new feature takes twice as long because nobody understands the old code. The original developers left years ago. The documentation is outdated or missing. Every change feels like defusing a bomb.

According to the Consortium for Information and Software Quality, poor software quality costs U.S. businesses over $2 trillion per year. The bulk of that comes from technical debt - the invisible tax you pay every time someone touches old, undocumented code.

Undocumented systems are the worst offenders. When the only person who understood the code is gone, even a simple bug fix becomes a multi-day investigation. The GitHub Octoverse report shows that developers spend more time reading and understanding code than writing it. Without a map, your team is lost.

Codebase Structure Mapping

Builds a complete map of every file, every dependency, and every connection in your application. You finally see the full picture of what you are working with - even if nobody documented it before. No more guessing what the code does or how modules connect.

Dead Code Detection

Old features, abandoned experiments, and copy-pasted blocks pile up over the years. The agent finds every line that is never called and gives you a safe removal plan. Less code means fewer bugs, faster builds, and a team that can move without fear.

Strangler Fig Migration

No risky big-bang rewrites. The agent wraps new code around old code piece by piece. Each section gets replaced while the system keeps running. Pairs with our QA Automation Engineer for full test coverage during migration.

Technical Debt Scoring

Every section of your codebase gets a debt score based on complexity, test coverage, and risk. You know exactly where to spend your time and budget for maximum impact. Stop guessing which fires to fight first - the numbers tell you.

Before: Legacy Spaghetti
Total lines: 48,000
Dead code: 12,000 lines (never called)
Framework: PHP 5.6 with known CVEs
Test coverage: 0%
Time to add a form field: 3 days
// Developer confidence: zero
After: Mapped and Migrated
Total lines: 36,000 (clean)
Dead code: removed safely
Framework: modern, patched, documented
Test coverage: 80%+
Time to add a form field: 2 hours
// Developer confidence: high

Logistics Company PHP Migration

A logistics company was stuck on a legacy PHP system built in 2011. Every change took weeks because nobody understood how the modules connected. The development team spent more time fixing regressions than building new features.

The Code Archaeologist mapped the full codebase, identified safe migration boundaries, and guided a strangler fig migration. The entire legacy system was migrated safely in 6 weeks - with zero downtime and no lost data.

Insurance SaaS Dead Code Cleanup

An insurance SaaS platform had grown over 8 years without cleanup. Dead features, abandoned experiments, and copy-pasted blocks inflated the codebase to 60,000 lines. Build times were slow and bugs appeared in code nobody remembered writing.

The Code Archaeologist scanned every file and found 12,000 lines of dead code - functions that were never called and features that were never shipped. After safe removal, build times dropped 40% and the team shipped their next release in half the usual time.

E-Commerce .NET Modernization

An e-commerce company ran a .NET 4.5 monolith with 200+ stored procedures and no documentation. New hires took months to become productive. Every release was a gamble because there were no automated tests and no dependency map.

The agent built a full dependency graph, flagged 34 stored procedures that were never called, and created a migration plan that broke the monolith into testable modules. The team went from monthly releases to weekly deployments in under 3 months.

Legacy Code - Questions Answered.

What does the Code Archaeologist actually do?

It maps your entire codebase, finds dead code, scores technical debt, and builds a safe migration plan. Think of it as an X-ray for your software - it shows you exactly what is healthy and what needs attention.

Will it break my existing application?

No. The agent uses read-only analysis first. It never changes code without your approval. When migration begins, it uses the strangler fig pattern - replacing pieces one at a time while the old system keeps running.

How long does a full codebase audit take?

Most audits complete within 48 to 72 hours depending on the size of your codebase. You get a full report with a dependency graph, technical debt score, and prioritized action plan.

Can it handle old PHP or .NET codebases?

Yes. The Code Archaeologist works with PHP, .NET, Java, Python, Ruby, and most legacy frameworks. It has seen codebases from every era of web development and knows the common pitfalls of each.

What is a strangler fig migration?

It is a safe migration pattern where new code wraps around the old system piece by piece. The old code keeps running while each section gets replaced. Once a section is fully migrated, the old piece gets removed. No big-bang rewrites and no downtime.

Do I need to give you access to my source code?

Yes, the agent needs read access to your repository. All analysis happens in a secure, isolated environment. We never share or store your code outside the audit process. Your intellectual property stays protected.
