About me

I come from the construction industry, where I have worked for years. Alongside it I learned web development through the Full Stack bootcamp at ConquerBlocks and on my own. I have no computer science degree. I have projects in production and real clients in Tenerife.

I build frontends with React and TypeScript, and backends with Node.js, REST APIs and SQL and NoSQL databases. I automate processes with n8n and AI APIs. I use Claude Code and Cursor to move faster.

I'm looking for my first position as a junior Full Stack developer in Spain, the Czech Republic or Slovakia, remote or on site.

I speak Spanish, Slovak, English and Czech. I hold EU citizenship and I am open to relocating.
