Fun Fact

I built a full-stack mobile dating app for pets, matching users based on pet personalities. What started as a school project now has over 1,000+ test users (and lots of fluffy love stories).

Passion

I’m passionate about building tech that solves real-world problems—especially in consumer apps and AI. I love turning curiosity into code, blending creativity with logic, and creating tools that connect people (or pets!) in unexpected and meaningful ways.
