How I turned technical knowledge into R$ 120K using Growth Marketing
Hi, my name is Jônatas Ricardo Santos, a Senior Fullstack Engineer with over 15+ years of experience, specializing in frontend development and currently expanding my expertise into AI and Machine Learning. I build high-performance, user-centric web applications using modern technologies like React, Next.js, TypeScript, and GraphQL.
Here I share projects, articles, and practical insights on frontend architecture, design systems, and how AI/ML is transforming the development landscape. I'm passionate about bridging beautiful interfaces with intelligent functionality — creating products that are both delightful to use and powered by cutting-edge technology.
