What I'm looking for

I’m looking for a team that values scalable back-end architecture—especially Ruby on Rails APIs and performance optimization—where I can contribute with reliable delivery, strong engineering practices, and room to grow into adjacent areas like mobile, UX, and Kubernetes.

I’m a Ruby on Rails developer with 8 years of experience building web applications. I’m proficient in Ruby on Rails and the JavaScript ecosystem, focusing on scalable back end design, API development, and application performance optimization.

I bring a System Engineering background from Universidad Nacional del Altiplano (Puno), and I enjoy tackling production-ready backend work while continuously improving how applications perform. Outside core development, I’m interested in Kotlin-Mobile development, UX, and Kubernetes.
