Senior Backend Engineer at Outforce building B2B pricing controls and payment validation for Tenda Atacado.

Brazil

Message

At Outforce, I launched item-level price negotiation for Tenda Atacado, modeling the pricing domain, API contracts, and persistence in Java 21 and Spring Boot. I also brought corporate payment terms into cart validation so incompatible payment methods are blocked before checkout.

At Onebrain, I built multi-provider payment integrations with automatic fallback for Food To Save and delivered 3D Secure authentication as sole owner. I also extracted payments from the monolith into a dedicated microservice and added rate limits to contain card-testing attacks.
