About Me

Hello! I'm Ranielli Montagna, a full stack developer passionate about turning ideas into innovative digital solutions. With over 3 years of experience, I specialize in creating web and mobile applications that combine exceptional functionality with intuitive design.

My journey began with a curiosity about how things work on the web, and since then I have been developing projects that positively impact people's lives. I believe technology should be accessible and make a difference.

When I'm not coding, you can find me exploring new technologies, contributing to open source projects, or planning my next development adventure.
