About myself :
I am a Middle+ Frontend Engineer with over 6 years of experience developing responsive, user -friendly web applications. My main expertise
is in the Vue ecosystem (Vue 2/3, Nuxt, Pinia, Vuex), complemented by recent hands -on experience in React and Next.js.
I specialize in integrating frontend components with backend APIs, performance optimization, migrations, and from -scratch development. I
also contribute to team growth by mentoring newcomers, conducting technical interviews, and improving processes.
• Optimized UI by migrating from jQuery to Native JS, implementing dynamic imports and scoped styles, which reduced bundle size by 30%
and improved site load time by 50%.
• Migrated the project from Vue 2 to Vue 3, updated libraries, fixed integrations, and switched to the Composition API, reducin g the bundle
size by over 20% and improving performance .
• Unified Frontend application standards (naming, structure, common practices), created documentation and a unified docker -compose,
which reduced the onboarding time from 3 days to 1 .
In addition, I have practical experience in Backend and DevOps (Docker, Nginx), that let me collaborate effectively in cross -functional teams
and complete infrastructure -related tasks independently.
I get excited about opportunities where I can make a real impact continuously contributing to code quality, engineering pract ices, and
product success.
