BSc (Hons) Computer Science & Data Analytics • LSSYB • CC • CCT
I try to see the world from a scientific perspective, always analyzing situations with reason and curiosity. I rely on logic to make sense of complex problems and uncover practical solutions. My belief in the power of numbers, data, and algorithms has shaped the way I think and act, driving me to approach challenges systematically. This mindset naturally drew me toward science and technology, where precision, structure, and innovation intersect. For me, every problem is like a puzzle waiting to be solved, and I find meaning in connecting patterns, identifying relationships, and transforming abstract ideas into practical applications.
At the same time, I strive to be the best version of myself — not by chasing perfection, but by embracing growth and self-discovery. I believe life is a continuous process of learning, unlearning, and relearning, where curiosity becomes the fuel for progress and resilience the anchor in times of uncertainty. Every challenge I face teaches me something new about my capabilities, and every success strengthens my belief that persistence, discipline, and vision can transform possibility into reality.
