Senior frontend developer focused on scalable, high-performance interfaces using React and Vue.
VietnamWhat I'm looking for
I’m a frontend developer with 5+ years of experience building interfaces from scratch or inside existing codebases—from landing pages and CRMs to large-scale B2B systems. I focus on architecture, performance optimization, and scalable solutions, while taking full responsibility for delivering results.
Most recently, I led frontend on a comprehensive school web platform, architecting client and admin parts and designing the commercial module from scratch. I set up linters and pre-commit hooks, optimized loading by removing unused styles, refactored for better structure, introduced type-safety and code review practices, and built a UI-kit with Vuestic UI for a team of 7 specialists.
Previously, I worked on a customer portal for freight and wagon repair services, developing new modules and services, refactoring and optimizing the codebase, and driving key migrations like Webpack → Vite and Vue 2.7 → Vue 3, including a shift to client-side routing. Earlier roles included fullstack development with React + TypeScript and NestJS APIs (PostgreSQL, webhooks, Docker) and B2B frontend work with Storybook, responsive UX, and localization (i18next), always pairing engineering discipline with practical delivery.
