Hi, my name is

Renée Paternesi.

I craft pixel-perfect web experiences.

I'm a Senior Frontend & Design Engineer with 13+ years of remote experience across product and service companies of all sizes. Specializing in React, Next.js, and Design Systems, I combine UI craftsmanship with AI-augmented workflows to accelerate engineering velocity and deliver flawless user interfaces. I thrive in fast-paced environments where I can take extreme ownership and just get things done, from early Figma explorations to polished production code.
