About me

Frontend engineer with a taste for hard problems.

I specialise in Angular — from architecting standalone component systems to leading version migrations (v12 → v22). I've worked on projects ranging from scientific research tools at CERN to enterprise client platforms at NEORIS, including a migration project for Universidad Europea de Madrid.

I'm comfortable owning a project solo or embedded in a cross-functional Agile team. My English is professional — I worked fully in English at CERN daily, across standups, code reviews, and technical documentation with colleagues from 30+ countries.

Currently open to remote roles with UK or US companies, both full-time and contractor. EU timezone, no visa sponsorship needed.
