Junior · Class of 2028 · Denver
I'm Eitan, a junior in Denver. I write code, play guitar, build audio gear, tutor math, run the business side of my school newspaper, and pick up languages for fun.
Code
01 ·
The website for Denver Jewish Day School's student newspaper, which I created. Readers get a fast static site with sections, an archive with search, staff pages and an RSS feed. Editors get a CMS (Keystatic) so they can publish without touching code.

OpenAbout
I’m a student, builder, and lifelong tinkerer. I like figuring out how things work, finding ways to make them better, and building things simply because I want to see if I can.
Most of my projects start with a question, an annoyance, or an idea I can’t quite leave alone. Sometimes that means writing software to solve a problem. Sometimes it means building electronics, experimenting with music, or finding a better way to do something I’ve done a hundred times before.
I’m a junior at Denver Jewish Day School, where I work on everything from student-built software to journalism and entrepreneurship. I write and manage the business side of The Paw, our student newspaper, and have taken on projects ranging from redesigning its website to developing apps and tools of my own. Outside the classroom, I tutor math through Calculus II, play guitar, and explore languages.
I’m interested in the intersection of software, engineering, and creative problem-solving. I don’t have one narrowly defined field I’m committed to yet, and that’s part of the fun. I’d rather keep experimenting, learn whatever a project demands, and see what I can make next.
This is where I keep the things I’ve built, the things I’m working on, and the ideas I’m exploring.
