Hi, I'm Jean Chavez

Building modern web experiences with Ruby on Rails, React, and Next.js.

About Me

I am a passionate Full Stack Developer with a strong foundation in both backend and frontend technologies. My journey involves building robust applications using Ruby on Rails and crafting dynamic user interfaces with React and Next.js.

Specialized in solving N+1 queries, designing scalable GraphQL schemas, and building serverless architectures. Recently, I've expanded my skillset to mobile development with React Native, allowing me to deliver cross-platform solutions.
