Development Approach

As a front-end developer, I focus on building clear, scalable, and visually engaging websites. I try to connect design and development so that what’s built feels coherent and intentional.

I focus on building full-stack applications with React and Next.js on the front end, and NestJS or Express with MySQL or Supabase on the back end. I also work with a range of APIs and libraries to extend functionality, while Tailwind CSS and Framer Motion bring structure and subtle motion to the interface layer.

Alongside development, I design prototypes and interface concepts in Figma and other tools, helping teams and clients visualize the product before it moves into production.
