What I'm looking for

I'm open to remote opportunities where I can build and own scalable Java backend systems, event-driven microservices, cloud-native platforms, and business-critical integrations.

At Unifio, I design and maintain Java microservices, REST and GraphQL APIs, enterprise integrations, and event-driven systems using Spring Boot, Apache Kafka, Google Cloud Pub/Sub, PostgreSQL, and AWS. I improved system uptime by approximately 40% and API response times by 20–40% through profiling, observability, and performance testing.

I also built backend automation with OpenAI APIs and Ollama that reduced professors’ exam creation time by 50%, while contributing React and Angular applications and end-to-end API integrations.

Previously, as Technical Co-Founder and Lead Backend Engineer at Websonora, I built the platform’s Java backend from scratch, scaled it to thousands of users, and led engineering practices. I integrated the product with Ford SYNC/AppLink for voice-driven internet radio navigation and continue teaching Software Engineering and Java Development at FATEC Ourinhos.
