Available to hire
I’m Emanuel Carneiro, a seasoned Full Stack Software Developer specialising in mobile and web apps built with .NET C#, React Native, React.js, and cloud architectures. I’ve delivered greenfield and legacy projects for startups, global brands, and government organisations, thriving in fast-paced teams or working independently. I love turning complex requirements into robust, scalable solutions and collaborating across product, design, and ops to ship high-quality software.
Outside work, I’m a builder at heart and enjoy exploring AI-assisted tooling to improve code and development processes. I’ve also got a long-running passion for eSports and music, which keeps me creative and driven.
