Driven by curiosity and a love for knowledge, I took on roles as a research assistant, academic tutor, and practicum guide in Software Engineering. Teaching and learning went hand in hand.

Claiming Victory

2021

Achieved 2nd place in the INTEGER #3 Development Competition, my first taste of competitive success, and a big motivator to keep pushing forward.
