## About

```text
At HOUM, I built an agent on the OpenAI API that checks generated contract documents against system data, identifies discrepancies, opens a support ticket, and proposes a fix as a pull request. I also took user requirements through to production and delivered workflow improvements that automated manual tasks.

At OnReady, I built Alternativa Teatral’s payment system with Spring Boot and the Mercado Pago API, and implemented event-driven concurrent-session controls for live streams with RabbitMQ. Earlier, I built internal tools and REST APIs with Spring Boot and React at Connectis, where I also coordinated client requirements and led teams of 2 to 4.
