Message

At EverOn Data, I modernize a cloud-native SaaS platform with 29 microservices, improving Kubernetes resource management and scalability through autoscaling. I also contribute to CI/CD workflows, production support, and deployments across environments.

I’ve built features for B2B SaaS platforms, including REST APIs and external integrations that let customers complete purchases directly through the platform. At Renova Soluções em Tecnologia, I reduced support tickets by 85% through frontend modernization, backend refactoring, and usability improvements.
