/services / legacy-modernization

Old codebase. New life — with AI.

Decade-old frameworks, tangled monoliths, undocumented SQL — we audit your existing codebase and modernize it with AI-assisted tooling. What used to take a full rewrite now takes weeks.

§ Capability

What we modernize.

  • [01] Analysis · Risk map · Roadmap

    Codebase Audit

    AI-powered scan of your codebase: dead code, security gaps, framework age, coupling hotspots. You get a written report and a prioritized modernization roadmap.

  • [02] Refactor · Tests · Deps

    AI-Assisted Refactoring

    We run structured refactoring passes with LLM tooling — renaming, pattern extraction, test generation, dependency upgrades. Senior engineers review every change.

  • [03] Re-platform · Migration · CI/CD

    Framework & Runtime Upgrades

    Migrate from end-of-life frameworks (Rails 4, Angular 1, PHP 5, .NET Framework) to modern equivalents without a full rewrite.

  • [04] Docs · Unit tests · Coverage

    Documentation & Test Coverage

    AI-generated docs and test suites anchored to your actual behavior, reviewed by engineers who read the code.
