What I'm looking for

I seek senior frontend roles focused on design systems, accessibility, and performance where I can mentor engineers and shape frontend architecture.

I am a senior front-end engineer with 5+ years building and scaling Vue and React applications, focused on accessibility, performance, and frontend architecture.

As core maintainer of design systems and component libraries, I led development of 40+ reusable accessible Vue.js components and reduced UI development time by 30% across projects.

I mentor junior engineers, deliver trainings that elevate code quality, and define measurable performance targets using Core Web Vitals and Lighthouse.

I have implemented analytics dashboards, payment integrations, and performance automation while contributing to open source (VBox/veebox.xyz) and working across cross-functional teams to ship impactful user interfaces at scale.
