University of Toronto student passionate about software development, system design, and creating innovative solutions that solve real-world problems.
Turning ideas into polished, real-world software.
I'm a Computer Science Major at the University of Toronto with minors in Mathematics and Statistics. I have a strong foundation in programming principles and a passion for building efficient, reliable software.
My academic journey combines mathematical rigor with hands-on software development. I'm particularly interested in software development and systems, designing full-stack applications, backend services, and developer tooling that solve real-world problems.
I've been actively involved in the Computer Science Student Union as the President, after serving as Vice President of External Relations for two years, where I secured sponsorships and organized events to enhance professional development opportunities for students.
I'm currently seeking internship opportunities where I can apply my skills in software development and systems to contribute to meaningful, real-world projects.
