A bit about me

I'm a frontend developer and, when a project calls for it, I also work on the backend. I specialise in turning complex business processes — logistics, inventory, IoT monitoring, payments — into interfaces people can use without a manual. I work with agile methodologies, mainly Scrum, and I'm comfortable leading a team's frontend.

I care about the details: clean code, reusable components, accessibility and performance. I learn fast and I enjoy projects where you have to understand the domain properly before writing the first line.
