Hi, I’m Natalia. I don’t just write code; I build digital engines that drive business growth. As a Full Stack Developer with a focus on the MERN Stack (MongoDB, Express, React, Node.js), I specialize in building custom web applications that are as beautiful as they are robust. My goal is simple: to take your "back-of-the-napkin" idea and turn it into a fully deployed, revenue-generating product.
