About me

I'm Gabriel, a full-stack developer based in Zaragoza, Spain. I like owning the whole product: from the data model and the API to the screen people touch and the pipeline that ships it.

I'm looking for a team where I can contribute from day one and keep learning from people who know more than I do.

Spanish

English

Conversational, no official certificate
