What I'm looking for

I'm looking to continue modernizing enterprise applications, building scalable cloud-native APIs and microservices, and contributing across .NET, Azure, AWS, CI/CD, messaging, and modern frontend technologies.

At Banco Rendimento, I lead the migration of legacy applications into microservices and serverless architectures, building scalable APIs and cloud-native applications with .NET Core, Azure, and AWS.

Over 14+ years in enterprise software development, I've delivered and supported applications for Pago Livre, Sebrae, Eicon, CLM Controller, and Ecom Energia. My work spans public-finance monitoring, back-office systems, REST APIs, and legacy application modernization.

I work across Angular, React, Node.js, and NestJS, connecting systems through RabbitMQ, AWS SNS, and AWS SQS.

I also build CI/CD pipelines with Azure Pipelines and Docker, apply CQRS and SOLID principles, and use xUnit and TDD to support reliable delivery.
