Sebastian Rivas

Freshman at the University of Miami studying Computer Science with minors in Mathematics and Quantitative Economics. I care about writing efficient software and understanding the systems behind it. My first instinct with any new device is to open the settings.

The more I learn about data science, the more I want to understand how to use data not just correctly, but optimally.

That same instinct is shaping how I approach my studies. I've been learning SQL on my own time because I find the challenge of querying and structuring data efficiently to be genuinely fun. I want to be at the cutting edge of technical advancement in performance, whether that means systems, data, or the tools that connect them.
