What I'm looking for

I’m looking to lead and build cloud-native platforms end-to-end—modernizing legacy systems, scaling real-time telemetry/geolocation, and driving CI/CD, observability, and engineering culture through ownership and technical excellence.

I’m a technology executive and hands-on software architect with deep experience leading engineering teams and modernizing legacy platforms into cloud-native, high-availability systems. As CTO at Garupa Desenvolvimento de Sistemas LTDA, I delivered approximately US$140,000 in annual savings, scaled mobility/payments/geolocation/telemetry workloads, and raised an application rating from 2.3 to 4.6 through backend performance, API reliability, and improved mobile experience.

I thrive on building distributed, event-driven architectures—architecting TypeScript and Laravel microservices with DDD patterns, expanding observability and real-time operational monitoring with Redis, RabbitMQ, and Kubernetes, and accelerating deployment cadence to three releases per week via CI/CD automation. Previously, I founded a connected mobility/location intelligence company in Slovenia, working across IoT/telematics, Bosch eCall integrations, and real-time streaming—then contributed to large-scale IoT telemetry platforms in Brazil as a backend developer.
