Case studies

Inherited app nobody wanted to touch

Operations-heavy business

A business bought a company with custom software the previous developer abandoned — stabilized without a full rebuild, anonymized example.

Problem

After an acquisition, the operations team relied on a half-finished internal app. The original developer was gone, deployments were manual, and critical workflows failed weekly.

What changed

  • Audit mapped what could be fixed vs rebuilt
  • Stabilized authentication, backups, and the highest-risk workflows first
  • Documented the system so a future hire could maintain it
  • Deferred full rebuild until the business case was clear

Result

Critical workflows ran reliably within one fix sprint. The team stopped maintaining parallel spreadsheets “just in case.”
