The challenge
The platform could not carry the next five years: weekend deployments reversed one in five, and inconsistent Polish character handling.
What we did
We placed a ten-person pod using a strangler approach behind a stable API layer, fixing Polish character handling with regression tests.
Results
- Częstotliwość wdrożeń z miesięcznej do kilku razy w tygodniu
- Wskaźnik nieudanych zmian z około 20 procent do poniżej 4 procent
- Pokrycie testami wyodrębnionych usług na poziomie 80 procent od niemal zera
- Dobrowolna rotacja w zespole inżynierskim niższa o ponad połowę
Why it worked
Two other firms quoted a full rewrite; incremental extraction was slower on paper and faster in practice.
