Brazil

Message

At Solutions in BI, I developed production applications for clients and built an AI assistant with asynchronous Python, FastAPI, Redis, and PostgreSQL. I integrated LLM tool calling and multimodal document processing.

I also designed a distributed data-processing pipeline using RabbitMQ, AWS S3, and MongoDB, and automated data collection from Brazil’s PJe court system. I set up production observability and distributed tracing with OpenTelemetry and Jaeger.

At MyTechWare, I developed Python microservices connected to a core C# system through gRPC, reducing medical teams’ report generation time by approximately 40%. I also built a hospital telemetry monitoring system with a Vue.js 3 front end and a C# back end.

I co-founded Fractal and led four developers in delivering a full-stack location-tracking mobile app. My projects include an accessible smart intercom with real-time video and remote door control, and a workout-tracking platform built around modular architecture.
