Jadson Torres de Lucena
Software Engineering Coordinator | Engineering Manager | Software & Cloud Architecture
Recife, Brazil
Summary
I contribute to teams delivering faster by building systems that are secure by design, reliable, scalable, and resilient. I transform complexity into clear architectures—guided by data, clear boundaries between domains, and a docs-first approach that keeps stakeholders aligned—while raising quality and engineering standards within the teams I work with. I enable safe, fast delivery through automation, gradual rollouts, and cloud-portable design that avoids vendor lock-in.

- Quickly grew into end-to-end feature ownership, increasing team throughput and freeing senior engineers for higher-complexity work.
Undergraduate Researcher, Scientific Initiation Program (PIBIC/CNPq), Federal University of Pernambuco (UFPE)
- Researched one-shot face verification using a SqueezeNet-based Siamese CNN with contrastive loss to distinguish identities from a single training image.
Municipal Civil Guard, Recife City Hall
- Developed discipline, respect for hierarchy, and strict adherence to operational protocols. As a Patrol Chief, I led teams in critical situations where decisions carried operational and legal consequences. This shaped my ability to make assertive and accountable decisions under pressure. In technology, I apply the principle that security and compliance belong throughout the project lifecycle—not only at the end—and deliver systems as resilient and reliable as the operations I led.
