ABOUT
Passion, Creativity, and Code
Rainer Drummond
Designer and Frontend Engineer
Hi, I'm Rainer — a Designer and Frontend Engineer from Brazil with over 5 years of experience. My journey started in design, and that has completely shaped the way I develop: I think about interfaces before code, value visual clarity, and prioritize seamless experiences.
Over the past few years, I've been part of high-impact projects in the financial sector, including a management system that processed over 375,000 transactions. This experience reinforced my attention to architecture, performance, code quality, and interface consistency.
My focus is on transforming ideas into real products, combining my background in Design and UX with advanced Frontend development, clean code and componentization best practices, plus experience in API integration and back-end development with Node.
I aim to contribute to teams that value quality, collaboration, and innovation — delivering solutions that are visually solid, technically robust, and truly useful for users.
If you want to create something exceptional, let's talk.
