Senior Sistemas

Identity, access, and performance improvements

Worked in the architecture team on authentication and high-volume domain filtering across a multi-product enterprise platform.

Back to case studies

Challenge

What needed to be solved

The platform needed stronger identity infrastructure and faster, more reliable filtering between systems without sacrificing maintainability.

Authentication had to support diverse protocols and many downstream applications.
Filtering workloads were performance-sensitive and had to be production-safe.
Platform reliability depended on strong tests, observability, and operational discipline.

Contributions

What I owned

The emphasis here is on the parts of the work that demonstrate engineering judgment, system thinking, and execution under constraints.

Implemented SAML, LDAP, and Keycloak-based authentication covering 50+ applications.
Delivered the Abrangencia filtering feature with Redis caching and comprehensive tests.
Expanded test coverage past 80% and reinforced quality practices through reviews and mentoring.
Used RabbitMQ, Kong, Grafana, Kibana, and Terraform to support stability and incident response.

Outcomes

What changed

The strongest evidence in these projects comes from reliability, speed, throughput, and the amount of operational drag removed from teams.

Reduced average query response time from 500ms to 200ms.
Improved throughput for high-volume filtering operations.
Contributed to 99.5%+ availability targets and MTBF beyond six months.

Takeaway

What this says about how I work

Good architecture work is rarely just about adding components. It is about making security, performance, and maintainability reinforce each other instead of competing.
