What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can lead teams and drive impactful projects.

With over a decade of experience in software engineering, I have had the privilege of working with some of the world’s largest companies, including DoorDash, GitLab, and Brazil’s most successful unicorns. I pioneered the establishment of the Brazil engineering office at DoorDash, playing a key role in scaling the team to over 50 engineers while shaping technical direction and mentoring local talent. My commitment to building scalable, high-performance applications is matched only by my dedication to the open-source community, where I have made significant contributions to projects like NestJS and Kubeless.

Currently, as a Staff Software Engineer at DoorDash, I focus on developing Trust & Safety infrastructure to ensure the authenticity of Dashers. I thrive in fast-paced environments, where I can leverage my skills in system architecture and team leadership to drive innovation.

My experience spans founding startups, engineering leadership, and large-scale system design, where I have consistently delivered solutions that enhance user experiences and optimize operational efficiency.
