Summary
UI / Frontend Developer with extensive work of commercial production experience, focused entirely on the presentation layer, high-quality layout, and frontend interface logic. I am a purely practical, results-driven developer: my core strength is transforming Figma layouts into pixel-perfect, highly responsive, and user-friendly interfaces strictly on time.
Over many years of successful work in one company, I mastered component-oriented development using Vue.js (Vuetify), reactjs, modern styling (Tailwind CSS, SCSS, Bootstrap), and legacy template engines (Twig, Smarty). I excel at digging into existing codebases, safely refactoring legacy layouts, and working in sync with backend teams via Docker. By integrating AI-assisted development tools into my daily routine, I eliminate manual boilerplate coding and deliver production-ready UI at an accelerated pace.
