What I'm looking for

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

I am a Senior Software Engineer with a passion for building impactful, high-performance web and mobile products. Currently, I lead frontend engineering for the React-based March Madness Live app at Warner Bros. Discovery, where I have successfully developed features that support millions of fans during tournament peaks. My expertise in React, Node.js, and AWS allows me to deliver real value to users through clean architecture and effective team collaboration.

Throughout my career, I have built dynamic interfaces and integrated real-time systems that enhance user engagement. I take pride in mentoring junior engineers and collaborating with cross-functional teams to create high-visibility features. My commitment to accessibility and performance has led to significant improvements in SEO and user experience, achieving 92% frontend test coverage across core features. I am excited to continue pushing the boundaries of technology to create innovative solutions.
