## About

```text
At Turing, I build Java and Spring Boot services for goHenry/Acorns Early, including a Backend-for-Frontend that exposes REST endpoints to the mobile app and translates requests into GraphQL queries.

At Ambev Tech, I served as technical lead of a development squad and helped modernize an invoice-management platform from a monolith toward cloud-native, multi-tenant microservices on Azure. I also redesigned core workflows around event-driven architecture.

At HST, I built secure payment-tokenization services in a PCI-regulated environment and maintained Java EJB systems. Earlier, I developed clinic-management features and APIs at B2ML Sistemas and supported legacy Java systems at Tata Consultancy Services.
