Legacy application modernization

Most legacy systems cannot be switched off, which rules out a rewrite. We staff engineers who modernize incrementally: assess what the system actually does, put an interface in front of it, and move logic out piece by piece while the old system keeps writing the record.

What the engagement covers

How it runs

  1. 01

    Scoping call

    A 30-minute call to establish what exists today, what has to be true at the end, and what the real deadline is. No proposal is written before this.

  2. 02

    Matched team in 48 hours

    You receive three to five profiles with the specific experience the work needs, their rates, and their availability. You interview whoever you want.

  3. 03

    Paid trial, then commitment

    Most engagements start with a short paid trial on a real task. You pay nothing until you decide to hire, and nothing at all if the trial does not convince you.

  4. 04

    Delivery with a named owner

    One person owns the outcome and reports weekly against what was agreed. Scope changes are priced before they are built, not after.

When this is the wrong choice

If the business logic is genuinely unknown and undocumented, expect the assessment to take longer than anyone wants. That phase is where modernization projects are won or lost.

Frequently asked questions

Rewrite or modernize?

Rewrites fail most often on the parts nobody remembered. Incremental modernization is slower on paper and finishes more often, which is why we default to it.

Which legacy stacks do you cover?

.NET Framework, Java with JSP or Struts, ColdFusion, Delphi, VBA and Access, classic PHP, and WinForms desktop applications, among others.

How long does modernization take?

A mid-sized application typically takes six to eighteen months of part-time engineering. The first milestone, usually an API in front of the legacy core, lands in weeks rather than months.
