Frontend Engineer & UI Craftsman
Javier
Rivas
Building scalable, accessible interfaces with React and TypeScript. Proven ability leading feature projects from planning to release.
Introduction
About
I'm a frontend engineer with 4+ years of experience building scalable, accessible user interfaces. I specialize in React, TypeScript, and modern frontend tooling, with hands-on experience in design systems, structured release cycles, and testing practices.
At DataRobot, I progressed from Associate to Frontend Engineer II, owning feature projects end-to-end — from planning and technical specs through testing and stakeholder sign-off. I thrive in fast-paced environments where quality and collaboration go hand in hand.
“I believe great interfaces are invisible — they empower users without getting in their way.”
My journey started in Industrial Engineering at ITESM, which gave me a systems-thinking mindset I bring to every line of code. When I'm not coding, I'm exploring new tools and approaches to make the web more accessible and performant.
