Frontend Developer Building Fast and Scalable Web Applications

I specialize in React, Next.js, and modern frontend architecture, creating performant and user-focused applications.

About

Building for the web, one component at a time.

I'm a frontend-focused software developer with experience building production web applications using modern technologies like React, Next.js, and TypeScript.

I work in a startup environment where rapid iteration, product ownership, and pragmatic engineering are required. I'm currently focused on advancing toward senior-level frontend engineering, with a strong emphasis on architecture and system design.
