What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth opportunities.

With over 11 years of experience in software development, I am a seasoned Full Stack Software Engineer dedicated to designing scalable and high-performance systems. My journey has taken me from Brazil to the United States, where I have honed my skills in developing enterprise-scale applications and RESTful APIs. I thrive in collaborative environments, having successfully improved cross-team communication and mentored engineers to foster a culture of technical excellence.

Throughout my career, I have led significant projects, including the development of large-scale systems for major companies like Apple. My expertise spans various technologies, including Ruby on Rails, PostgreSQL, and cloud services such as AWS and Azure. I am passionate about performance optimization and automation, consistently seeking innovative solutions to enhance system efficiency and reliability.
