IT and Operations Director, Fleet-Scale IoT Infrastructure @ D3S

Led IT, infrastructure, and operations for a large-scale vehicle tracking platform supporting more than 15,000 monitored vehicles, including approximately 3,000 vehicles from the police fleet of the State of Mato Grosso.

Worked across IoT tracking devices, telemetry ingestion, server infrastructure, databases, network architecture, field operations, and service delivery to keep critical fleet monitoring systems operational under real-world constraints.

Integrated, adapted, and reverse-engineered locked-down tracking devices and heterogeneous equipment, dealing with proprietary behavior, limited documentation, communication constraints, and inconsistent device-side assumptions.

Tuned servers, databases, and network environments to support continuous telemetry workloads, intermittent connectivity, high-volume device communication, and operational responsiveness across a distributed fleet.

Led technical teams, incident response, infrastructure planning, and service delivery for systems where reliability, observability, and data availability had direct consequences for fleet visibility and public safety operations.

This work became one of the foundations of my later focus on IIoT security, distributed infrastructure, critical systems engineering, operational resilience, and adversarial failure modeling.
