ABOUT ME

👨‍💻

ALEKSANDR ZHOLOBKO

Frontend Developer · React · TypeScript · Vue.js

Frontend developer with 4+ years of commercial experience. I specialize in React and Vue.js with TypeScript. I build scalable UI solutions: from component libraries and design systems to complex scroll-animations with GSAP and SSR/SSG pipelines.

Experienced in fintech product teams where reliability and code quality are paramount. I conduct code reviews, configure build systems (Webpack 5, Vite), and work with multilingual interfaces supporting 26 languages.
