Enterprise systems

Maintenance and implementation of new requirements in internal enterprise systems for data management, attendance control and operational flows.

Problem

Legacy internal systems with coupled code and modules that needed new features (data management, attendance, operational flows) without interrupting operation.

Solution

  • Modular refactor on Java + Spring Boot, separating responsibilities by domain.
  • New REST endpoints with validation and pagination.
  • Unit test coverage on critical modules.

Result

  • ~20% reduction in operational costs reported by internal clients.
  • ~40% software quality gain attributed to the test suite.
