Pedro Nieto

I'm a Software Developer with over 3+ years of experience in building scalable, robust, and accessible applications.

Currently, I'm a Mid-level Full-Stack Software Developer at Capgemini, specializing in backend development. I contribute to the design and maintenance of services and BFFs consumed by Micro Front-ends (WebApps), leveraging Hexagonal Architecture and ensuring adherence to accessibility standards and development best practices.

In the past, I've had the opportunity to develop software in a variety of environments — from security, connectivity, and energy companies to clinical management software companies. I also developed some NPM packages and contributed to open-source projects. I usually showcase my work on my GitHub.

In my spare time, I’m usually studying, reading, playing volleyball or running. I also enjoy contributing to open-source projects and exploring new technologies. I’m always eager to learn and grow.
