Hi, I'm Richard
Freelance software developer based in Cuba, building custom software for companies worldwide.
Where I come from
I'm a Computer Science Engineer, graduated from the University of Informatics Sciences (UCI) in Havana (2018–2023). Since 2022 I've been building web software, working remotely with teams and companies in different countries.
I started as a freelance junior web developer working with HTML and CSS, then moved into software engineering and full stack work. Today I work as a front-end developer on e-commerce and B2B projects. I combine frontend with DevOps, software architecture and functional requirements, and I maintain my own open source projects.
