About

I'm a software and data engineer with a passion for building AI-powered applications that solve real-world problems. My journey into tech is non-traditional — I transitioned from a career in professional tennis coaching and healthcare, bringing a unique perspective on communication, problem-solving, and user empathy to every project I build.

Currently, I'm focused on building conversational AI systems at Oral AI, where I develop HIPAA-compliant voice agents that automate front desk operations for dental offices. Previously, I've built recommendation systems at Wheare, personality-driven AI companions at Cyber Partner AI, and educational AI tools at Reality AI Lab.

I'm most energized when working at the intersection of machine learning, full-stack development, and data analytics — crafting solutions that are both technically robust and genuinely useful to the people who use them.

When I'm not coding, you'll find me on the tennis court, exploring new restaurants, or diving into the latest developments in AI and machine learning.
