BrazilWhat I'm looking for
I am a senior software engineer with 10 years of experience building scalable, high-quality systems using JavaScript, Node.js, and modern cloud-native patterns.
I have led backend and architecture initiatives across e-commerce, fintech, Web3, and security domains, delivering measurable operational improvements such as reducing video incident handling time and optimizing high-throughput event processing.
I design and implement microservices, serverless backends, event-driven systems, and observability solutions using technologies like Nest.js, Kafka, Kubernetes, AWS, and GraphQL, while promoting Clean Architecture, DDD and functional programming practices.
I mentor teams, created reusable tooling (for logging and developer ergonomics), and consistently drive migrations to modern architectures to increase scalability, reliability, and developer productivity.
