About me

Hi, I'm Sergio Corral. The curiosity to understand how things work has always been with me. Today, I focus on developing full-stack solutions and automated systems that connect technology with the world.

Throughout my career, I have worked on development projects combining web development, automation, and cloud deployment. My experience covers Node.js, React, Python, Java, and C#, along with DevOps tools such as Docker, Git, CI/CD pipelines, and cloud platforms (AWS, Azure, Google Cloud).

I have also worked on blockchain automation projects, creating bots that interact with smart contracts to execute optimized operations on networks like Ethereum and Ronin.
