           <p>I study Maths for my bachelor&apos;s degree and I&apos;m always awed by the beauty of it (as the motivation to learn it through so much hard work)! I love the outline of analysis proofs and I&apos;m especially obsessed with algebra structures.</p>
           <p>I also learn some computer science and data science, and I find myself better at them than Maths lol. I&apos;m drawn to the problem solving, ideas behind product design, and the empathy I feel when I&apos;m building something for humans.</p>
