What I'm looking for

I seek roles building scalable, observable systems and high-impact products, with strong engineering practices, mentorship, and opportunities to improve performance and reduce costs.

I am a Senior Software Engineer with extensive experience designing and delivering full-stack and serverless products that serve millions of users. At Toro Investimentos I built a learning platform and a Flutter portfolio experience, contributed to app quality and observability, and drove revenue-impacting investment products using clean architecture.

Previously at Tecnospeed I developed high-throughput producer-consumer systems in Node.js, introduced robust test suites and CI/CD quality gates, and led cost-saving migrations and pipeline optimizations that improved performance and reduced costs.

I hold a Computer Engineering degree and I focus on scalable systems, observability, and developer productivity, enjoying mentoring and running workshops to upskill teams and improve delivery.
