Why I Do What I Do

My mission is to heal, educate, and uplift.

As an aspiring mathematician, I’m not just chasing equations — I’m pursuing solutions to real-world problems. I believe mathematics is a universal language that can drive innovation, bridge inequalities, and improve lives. Whether it's advancing education, shaping policy with data-driven insights, or developing tools that solve everyday challenges, my goal is to use the power of math to create a smarter, fairer, and more compassionate world.

Core Values:

  • Compassion in Action
  • Education for Empowerment
  • Integrity in All Endeavors
  • Persistence Through Challenges
