Freelancer profile translated to English.
Back to original languageAbout Ruben
I am a developer with experience in web development with React and in building automation systems using N8N. I work as a technical consultant in the Microsoft ecosystem, which has given me a solid understanding of how businesses need technology to work in reality, not just on paper.
I specialize in two specific areas:
Automations with N8N — I connect tools, eliminate repetitive manual tasks, and integrate services that otherwise wouldn't communicate.
I have built complete pipelines ranging from data capture to automatic content publishing, notifications, reports, and more.
Web development with React — clean, functional, and easy-to-maintain interfaces. I work well on both greenfield projects and improving existing ones.
If you have a time-consuming manual process, an integration that isn't working correctly, or need a custom web tool, I can help you solve it directly and without bureaucracy.
Limited availability — I work with a few clients at a time to ensure quality and quick responses.
