Legacy Code Modernization as a Service
Migrate obsolete COBOL, PHP 5, and Delphi codebases into modern Go, Rust, or TypeScript with comprehensive automated test suites.
📊 Financial & Retainer Economics
🎯 Market Opportunity & Why Clients Pay For This
Thousands of financial institutions, hospitals, and supply chain operators run on legacy code written in COBOL, PHP 5.4, or Delphi. The original developers have retired, and nobody on the current team dares touch the code. System integrators (like Accenture or IBM) quote $500,000+ and 2 years to rewrite these systems. By utilizing frontier coding models with massive context windows (like Qwen3.8 and Claude Code), you decompile legacy routines, generate comprehensive test fixtures that capture exact input/output parity, and translate the codebase into clean Go or TypeScript in weeks.
Target Customer Niches (Ideal Customer Profile):
- Regional banks and credit unions running legacy COBOL/AS400 core routines
- Logistics & warehouse companies running 20-year-old Delphi / Visual Basic 6 desktop apps
- Municipal governments and universities with unmaintainable PHP 5 / Perl web portals
- Manufacturing firms with legacy Fortran or C billing calculations

Subject: Modernizing [Company Name]'s [System/Language] codebase without hiring Accenture Dear [IT Director Name], Many organizations in [Industry] face the same hidden liability: core billing and operational workflows depend on legacy [COBOL/PHP 5/Delphi] applications that modern developers refuse to touch. Traditional enterprise consultancies quote 18-month timelines and half a million dollars to rewrite these systems. We run an AI-accelerated migration service that decompiles legacy code, generates automated test fixtures to guarantee 100% numerical parity, and migrates logic into clean, containerized Go or TypeScript in weeks. We recently modernized a 15,000-line legacy calculation engine for an insurance broker with zero business disruption. Could I offer a 100% confidential audit of one legacy module to show you the translation and test parity report? Sincerely, [Your Name]
❓ Frequently Asked Questions
How do you ensure no subtle financial rounding errors occur?
We generate automated behavioral test fixtures that run both the legacy binary and the modern code side-by-side on thousands of historical database inputs to verify exact numerical parity.
