Maintenance & legacy modernization
Stabilization, retroactive tests, incremental refactor
We have a serious track record with legacy Delphi, C++, PHP, MS SQL, Firebird. We stabilize them, write tests, refactor in slices. No big-bang rewrites.
- 01
Codebase audit with prioritized report
Hot spots, cyclomatic complexity, code smells, dangerous dependencies. Output: what to touch first, what to leave alone.
- 02
Retroactive test harness
We add regression tests on existing code before we touch it. Cover critical cases so we can refactor without fear.
- 03
Strangler pattern migration
New routes go to the new system, old routes stay on legacy. We migrate piece by piece, in months — not 18-month big-bang.
- 04
Documented knowledge transfer
Interviews with "the person who knows the system", converted into ADRs and runbooks. Knowledge no longer depends on one person.
- 05
Optional post-delivery on-call
We can stay available for critical incidents 30/60/90 days after handover, with a clear SLA. No hidden retainer.
