What I'm looking for

I'm seeking a back-end engineering role where I can apply Python, cloud-native infrastructure, and RLHF expertise to build scalable, high-performance applications and improve aligned AI systems within a collaborative, growth-oriented team.

I am a back-end developer with 5+ years of experience building scalable microservices, managing cloud infrastructure, and developing database-backed applications using Python and NodeJS.

I have refactored legacy Django monoliths, led a Cassandra-to-PostgreSQL migration, managed Kubernetes microservices with KubeMQ and Rancher, and served as sole back-end developer responsible for DigitalOcean, Cloudflare, and multi-database operations. At Turing I collaborated with AI researchers to provide high-quality feedback and evaluations for Reinforcement Learning from Human Feedback (RLHF).

I hold a Computer Science degree from UFPEL, worked on game development with Unity, and pride myself on being a fast learner who delivers reliable, maintainable systems that advance product and AI goals.
