Acerca de Rafael
Full-stack product engineer with strong frontend expertise, focused on building modern web and mobile applications with clean UX and production-ready quality.
I’ve built and launched products used by 5000+ users, including True Resonance, a music player available as both a Chrome extension and mobile app, and MoneyBoard, a personal finance application.
I work mainly with React, React Native, TypeScript, and Node.js, and I’m comfortable integrating into existing teams, codebases, and delivery processes.
My strongest area is frontend and mobile development, but I’m also comfortable working across the stack, including backend logic, databases, and AI / LLM integrations when relevant to the product.
I’m particularly effective in environments where teams need someone who can ramp up quickly, work independently, and deliver polished features with a strong eye for usability.
Currently open to freelance and contract opportunities.
