- About -
Senior Frontend Engineer with 6 years building production SaaS in Vue 3, Nuxt and TypeScript: booking platforms, payment flows and data-heavy dashboards serving real paying clients. Author of two published npm libraries: a Nuxt 3 component library and a Vue 3 protocol library. I own frontend architecture end to end: component libraries, state management, testing, CI/CD, and API contract design with backend. Accessibility is a default, not a retrofit: WCAG 2.1 AA throughout, with client sites at 95 to 100 for accessibility and 100 for best practices. EU citizen, open to mid and senior frontend roles.
