What I'm looking for

I’m looking for a role where I can lead release automation and microservices delivery in AWS/Azure environments—combining strong engineering leadership, CI/CD, IaC, and continuous improvement to improve reliability and business outcomes.

I’m a Senior Fullstack Developer and Cloud Engineer with 30+ years delivering scalable, business-critical applications for global organizations. I specialize in Java, C#, React, Angular, and AWS, with a strong emphasis on microservices architecture, cloud infrastructure, and distributed systems.

In my current Release Manager role, I lead governance and orchestration for software releases in highly critical environments affecting 15M+ Bradesco customers. I drive CI/CD automation with Jenkins and Azure DevOps, apply “Release as Code” and IaC with Terraform and Ansible, and enforce compliance with LGPD, PCI-DSS, and SOX. I also improve operational outcomes—reducing average incident recovery time by 30% and increasing delivery frequency by 50%.

Previously, I’ve led engineering teams as a Tech Lead and built backend and fullstack services across AWS and Azure. I’ve worked with Python/Django, Spring/.NET, Kafka, Kubernetes (EKS), and multiple databases—always prioritizing performance, reliability, and continuous improvement through lessons learned.
