As a Senior Full-Stack Software Developer at Playbook Sports, I focus on building scalable, reliable systems and leading high-impact initiatives across the engineering team.

I oversee production deployments, review and authorize pull requests, and use CircleCI to maintain smooth, test-driven release pipelines. As the lead of our internal “Task Force,” I manage urgent bug fixes and client requests—reducing turnaround times and ensuring platform stability.

Beyond the code, I mentor junior developers, promote development best practices, and help shape a collaborative, quality-focused engineering culture.

With a B.S. in Computer Science from NJIT and hands-on expertise in AWS, Django REST Framework, React, and Agile methodologies, I’m passionate about turning complex problems into efficient, user-driven solutions that scale.
