Hi, I'm Josh. I like building things that matter.
I'm Joshua (Josh) Koppanalil, a sophomore at Westlake High School in Austin, TX, exploring computer science, cybersecurity, machine learning, and the ideas that connect them.
Always exploring.
My interests sit at the intersection of software, security, and engineering. I like learning how systems work under the hood, building projects from scratch, and collaborating with people who enjoy solving hard problems.
Outside of tech, I enjoy jet-skiing, mountain biking, playing soccer, playing piano, and getting some sleep.
Projects.
