Hi, I'm
Leandro Carlos Pereira
Software Developer focused on creating efficient, modern, and scalable solutions.
About Me
I’m a software developer with over 12 years of experience, having started in quality assurance and evolved into building modern, scalable systems. Throughout my journey, I’ve taken part in challenging projects at companies of all sizes, contributing to frontend, backend, and at times, infrastructure.
I have solid experience with technologies like JavaScript, TypeScript, React, React Native, Angular, Node.js, NestJS, and Java, along with practical knowledge of SQL and NoSQL databases. I've also worked with CI/CD tools, Docker, and AWS services, supporting application stability and continuous delivery.
Currently, I’m expanding my knowledge in Flutter and conversational English, while developing personal projects focused on learning and innovation.
I enjoy learning, teaching, and building with quality.
