Codebase Modernization

A second set of senior eyes on your existing system

Not every engagement starts from zero. Technical debt is cheap to fix early and expensive to fix after it's caused an outage or blocked a launch. We drop into an existing codebase for audits, refactors, and ongoing feature development, bringing senior-level judgment to a system someone else already built.

Who this is for

  • Teams with an existing codebase who need outside senior help
  • Companies without a long-term hiring commitment who still need staff-level judgment
  • Engineering teams that want an audit before a major refactor or scale-up

What you get

  • A codebase audit identifying risk, debt, and quick wins
  • Hands-on refactoring or feature work where it matters most
  • Ongoing improvement, scoped to what your team actually needs
