Brazil

Message

At UL Solutions, I lead development of a Chemical Product Authoring solution with Next.js, React, and TanStack. I also implemented SQL Server Temporal Tables for regulatory auditing and built a Spring Batch pipeline to migrate enterprise legacy data.

I developed an internal ticket-tracking chat assistant using Spring Boot and Spring AI, and created MCP tools with Python, FastMCP, and C# extensions to connect internal APIs with external platforms.

At Global Payments, I developed enterprise integration systems with Java 21 and MuleSoft, and designed standardized APIs using RAML and MuleSoft Anypoint Platform. I also maintained Java/Spring Boot and Vue.js applications supporting Pricing Operations and engineered a product-agnostic pricing engine.

Earlier, at DMCard, I led development of ASP.NET Core microservices for real-time credit card fraud assessment and risk analysis, and designed a billing system architecture that contributed to measurable annual revenue growth. Across my work, I’ve developed software for payments, ERP, compliance, IoT, and government technology.
