Mathematics and CS @ UofT, Previously @Arcadis

I'm a software engineering student passionate about creating technology that not only works well but works for everyone. My journey focuses on accessibility engineering, data-driven development, and building solutions that make a real difference in people's lives.

Through my internships and projects, I've learned that the best solutions come from understanding real user needs and measuring impact through concrete metrics. I believe in continuous learning and sharing knowledge with the community.
