About Me

What Drives Me

As an applied data scientist, I'm passionate about translating complex ML/NLP concepts into practical solutions that make a real difference in people's lives.

I believe AI should enhance human potential rather than replace it. This philosophy guides everything I build - from optimizing ML pipelines for real-world deployment to developing AI applications focused on human wellbeing.

Inspired by the next generation, I'm committed to building technology that creates a better future for our children and families.
