Software Engineer & Backend Specialist

Hi, I'm Jean Chavez

Architecting scalable systems with Ruby on Rails, Cloud Infrastructure, and Next.js.

About Me

I am a passionate Full Stack Developer with a heavy focus on Backend Engineering and DevOps. My journey involves architecting robust APIs using Ruby on Rails and deploying them to production environments using Docker and CI/CD pipelines.

Specialized in solving performance bottlenecks (N+1 queries), designing scalable GraphQL schemas, and managing Linux VPS infrastructure. I balance this technical depth with modern frontend skills in Next.js and cross-platform mobile development with React Native.
