About

As a passionate front-end engineer, I build scalable, maintainable, and high-performance web applications. My approach is built around three key pillars: - Clean code & robust architecture I design component-based, modular architectures using best practices like Atomic Design, Domain-Driven UI, and Composition API. I've worked extensively with React, Vue (2 & 3), TypeScript, Vite/Webpack, and Module Federation to structure reliable and future-proof codebases. - Testing & CI/CD I set up efficient continuous integration pipelines (GitLab CI, CircleCI) and implement complete testing strategies: unit tests (Vitest, Jest), component tests and end-to-end tests (Cypress, Playwright). I believe in shipping with confidence, not luck. - Monitoring & performance optimization I closely monitor Core Web Vitals and proactively optimize UX performance (code splitting, lazy loading, bundle size). I integrate tools like Sentry for error tracking, LogRocket/Hotjar for user behavior analysis, and Lighthouse for regular audits. I’m always eager to learn, share, and help teams reach the next level of quality and delivery speed in production.
