Software Engineer at SiDi modernizing GTC into .NET 10 and React, cutting response time by 71%.

Brazil

Message

At SiDi, I contributed to the technical evolution of GTC, a core enterprise platform for Compal Electronics. I helped re-engineer legacy .NET Core 3.1 and Angular applications into a .NET 10, React, Oracle, and MongoDB stack, reducing average response time from 630ms to 180ms under peak load.

At Banco do Brasil, I developed a .NET 8 REST API that consolidated agribusiness operational data into near real-time dashboards. I also optimized COBOL processes, reducing processing time by 30% for high-volume transactions.

At Ratto Software, I architected event-driven microservices with RabbitMQ and MassTransit for pension and insurance services. Using CQRS, the Outbox pattern, and idempotent consumers, I supported eventual consistency and maintained 80%+ test coverage.

At LAMPP-IT SOLUTIONS, I developed and maintained .NET Core applications for SUFRAMA, with Angular interfaces and SQL Server services. I also improved frontend performance by 35% through component design and state management in Angular and React.
