Who am I

I am Guillermo Serrahima, a Software Engineer from the area of Barcelona, where I currently live. I graduated from the Polytechnic University of Catalonia with a Degree in Informatics Engineering in 2018.

I am most comfortable when I am working with C++, Java, Python and Rust code. I am familiar with Git, Linux, and the command line. In my day to day I use Arch Linux as my main OS.

In addition, I have worked in the past with other languages like Golang, C, C#. I have worked on projects that used PostgreSQL, and I maintain SQLite and MySQL databases on my personal servers (depending on the scope.) I have used testing frameworks like GoogleTest and Pytest, and used CI/CD pipelines like Jenkins and GitHub CI/CD. I also regularly use Docker containers on both a profesional environment and my personal servers.

Languages

I speak Spanish and Catalan natively, and I hold and have used a professional level of English on all my job positions.
