About
Learn about me.
I'm a data analyst who likes turning messy data into clear answers. I earned my B.A. in Business Analytics at Cal State Fullerton, built a foundation in computer science along the way, and I'm now pursuing an M.S. in Analytics at Georgia Tech.
I've worked in broker-dealer operations and banking security analytics, and I build my own products, like Pokernow.ai, a real-time poker analytics platform serving 1,000+ concurrent users. Now I'm looking for roles where I can bring that skill set to analytics, BI and AI.
Beyond the technical side, I bring strong analytical thinking, data-driven decision-making, and clear communication to every team I work with. I do my best work in open, cross-functional environments where I'm always learning from the people around me.
On a more personal note, I was born in Seattle, WA and grew up in Irvine, CA. My hobbies include tennis/pickleball, surfing, cinema and traveling.
