@serhiiuser1

Front-end developer specializing in modern JavaScript frameworks and responsive UI.

What I'm looking for

I seek front-end roles focused on modern JS frameworks, component-driven UI, CMS integrations, collaborative teams, and opportunities to work on performant, user-focused web products.

I am a front-end developer with multi-year experience building HTML5/CSS3 interfaces and interactive JavaScript applications using Vue.js, React, Angular and supporting backend APIs. I deliver responsive, accessible markup and integrate CMS solutions like WordPress and Umbraco to produce production-ready websites.

My work history includes freelance projects and roles at agencies and product teams where I created markup templates, implemented component-driven UI with Nuxt and Vue, and collaborated on projects using Node.js, Express and REST/GraphQL APIs. I am comfortable with build tools (Gulp, Webpack), version control (GIT), and design handoff tools like Figma and Adobe Photoshop.

I focus on pragmatic, maintainable front-end architecture, component reusability, and close collaboration with design and backend teams to ship performant web experiences. I continually expand my skill set across modern frameworks and CMS integrations.
