What I'm looking for

I am seeking Full-Stack or Backend roles where I can build scalable, cloud-native systems, improve performance, and contribute to CI/CD and testing practices.

I am a Full-Stack Engineer with strong experience building and maintaining web and enterprise applications for clients across Brazil, the US, and Europe.

I have delivered scalable APIs, background workers, and dashboards that support millions of daily requests, using technologies such as Golang, PHP (Laravel, Symfony), Node, Angular, Ember.js, MySQL, MongoDB, PostgreSQL, Docker and Kubernetes.

I emphasize testing and reliable delivery: I implemented frontend and backend unit tests (Ember Test, PHPUnit), CI/CD pipelines, code reviews, and load/stress testing to improve performance and stability.

I have built domain-specific systems including hospital management platforms, clinic management solutions, and high-throughput e-commerce/order delivery systems, and I enjoy solving complex distributed-systems problems and improving operational metrics.
