EDS (Civil Police of Rio de Janeiro)

My consulting experience on sensitive public systems.

Context

In my consulting work for EDS, I worked on systems for the Civil Police of Rio de Janeiro. The context involved a critical public operation, a high-volume health management system, and an evolving legal ERP.

How I worked

I structured the health system backend with NestJS and SQL Server. I also refactored legacy routes and contributed to flows for process automation, document management, and evidence collection. Security, access control, traceability, and LGPD compliance guided how every route had to evolve.

Beyond backend work, I collaborated on shared design-system components to align API contracts with the interfaces used in the operation.

What I took from it

The work reinforced the care needed to evolve sensitive systems without losing auditability. Rather than separating security from delivery, I treated access and traceability as part of the product contract.
