About Me

I'm Jason, a senior at Columbia University studying Computer Science and Psychology. I got into tech because I love building things that people actually use: products that solve real problems and feel intuitive. My psychology background shapes how I think about users: what motivates them, what frustrates them, and how to design experiences that just work.

When I'm not coding, you'll find me backpacking, doing photography, or playing pickleball.

What I'm Looking For

I'm seeking software engineering roles where I can build user-facing products at the intersection of technology and human behavior. I thrive in environments where I can ship quickly, learn from users, and iterate.
