I'm a Senior Software Engineer with extensive experience in designing and implementing scalable microservices and cloud-native applications. Currently, I work at Disney Streaming, where I architect solutions that support global platforms like Disney+ and ESPN+. My role involves collaborating with cross-functional teams to define service-level objectives and improve system reliability through innovative practices.

Previously, I contributed to Hulu and Comcast Technology Solutions, where I focused on backend service development, cloud migrations, and API design. My passion lies in leveraging technology to enhance user experiences and drive operational efficiency. I thrive in environments that challenge me to push the boundaries of what's possible in software engineering.
