I am a backend developer dedicated to creating efficient and scalable solutions, with expertise in Domain-Driven Design (DDD), Clean Architecture, and best practices like SOLID. Throughout my career, I’ve contributed to optimizing large-scale financial systems, including improving microservices that handle billions of reais in the banking sector. With a strong focus on performance and innovation, I’ve implemented microservice architectures, optimized resources, and significantly reduced costs in critical environments.

My recent role as a Mid Backend Developer at Educbank involved creating and implementing new features related to loans for the educational sector. A key contribution was delivering a complete notifications system using WebSockets, which significantly improved users' ability to manage their invoices and enrollments. Additionally, I played a crucial role in refactoring Educbank’s billing system, enhancing security against fraud and resolving performance and cost issues by identifying and addressing several bottlenecks.

Previously, at BTG Pactual Bank, I was responsible for the development and maintenance of various microservices, focusing on a critical microservice in financial operations. I utilized technologies such as RabbitMQ, Kafka, Redis, MySQL, and AWS services to build and optimize solutions. My experience has equipped me with the skills to define service architecture, resolve bottlenecks, and improve performance, ensuring that systems effectively meet complex demands.
