Building fast and elegant web experiences with modern technologies
About me
I’m a Senior Frontend Developer with 14+ years of experience building modern, fast, and scalable web applications.
I specialize in the Vue.js ecosystem and performance optimization. I’ve led successful transitions from jQuery and Vue 2 to Vue 3, reduced page load times by up to 30%, and built real-time systems serving thousands of users.
My recent work includes migrating architectures, optimizing analytics pipelines (+25% data reliability), and reducing tech debt to zero.
I’m a pragmatic problem solver with a strong focus on clean code, efficient tooling, and user-centric design. I enjoy mentoring developers, working across teams, and translating business needs into technical solutions.
Tech I use daily: Vue.js, TypeScript, Tailwind CSS, Vite, Vitest, Stripe/PayPal integrations, CI/CD pipelines, WebSocket debugging, and performance profiling.
