Case Studies
Galpão das Máquinas - Legacy System Modernization Case Study
We modernized Galpão das Máquinas' legacy platform, rebuilding an unstable system into a robust, cloud-native architecture. By professionalizing CI/CD workflows and eliminating technical debt, we reduced downtime by 95% and cut maintenance costs significantly. The scalable foundation now supports rapid business growth without technical bottlenecks.
