Computer Science Student ✦ Full-Stack Web Developer

Editorial

I build web applications and digital products with an eye for performance, interface clarity, and code that stays maintainable after the first release. Most of my work sits around React, Next.js, TypeScript, and Convex, with systems shaped to remain legible as they grow.

I also care about what happens below the surface: how JavaScript and TypeScript execute, and enough C and C++ to keep the systems layer in view. When AI enters a product, I treat it as part of the architecture, not as a decorative feature.

I start with the problem, then try to leave the code simpler and clearer than I found it. Outside software, filmmaking and photography keep me attentive to pacing, framing, and the visual language around the work.
