What I'm looking for

I seek roles building scalable banking or fintech systems, collaborating with product teams, using .NET/React and AWS, with opportunities for domain learning and impact.

I am a full-stack developer with strong backend roots, focused on building and supporting high-demand banking systems using C#, .NET, React and AWS. I have experience developing microservices and front-end applications for credit risk, PIX and core banking routines, and helped deliver systems handling up to 10% of Brazil's PIX transactions.

I enjoy learning product domains and collaborating with Product Owners to meet customer needs; I have improved incident SLAs and implemented scalable solutions using PostgreSQL, MySQL, DynamoDB, Redis, RabbitMQ, Kubernetes and observability tools like Dynatrace and Grafana.
