FAQ

What services do you offer as a front-end developer?
I specialize in building fast, responsive websites and web apps using Vue.js, Nuxt.js, and TypeScript, with a focus on optimized UIs, reusable components, and top-notch performance—like boosting FCP by 41% or LCP by 36%. I also handle testing with Jest for reliability and can dip into back-end work with Node.js or PHP when needed.
How do you ensure a website performs well?
I boost website performance by tackling both SEO and loading speed. For SEO, I’ve lifted scores by 34% — fixing missing sitemaps, tweaking meta tags, and adding JSON-LD to climb Google rankings and pull in more clients. On the loading side, I refactor code, optimize images and animations, use lazy loading for components, preload key assets, and cut unnecessary API calls—plus, I’ve added Vue virtual scrolling for smooth handling of big data lists, making sites fast and user-friendly.
What’s your approach to working with clients?
I start by chatting directly with you to nail down your needs and design specs, then deliver interactive, user-friendly solutions on time — think adaptive layouts crafted with UI/UX designers or custom features. It’s all about collaboration and results.
Why should I choose you for my project?
With 2 years of experience across teams of 1-8, I bring proven skills — 90% test coverage, modular components, and a passion for both front-end and back-end (Node.js, PHP). My work’s already sped up sites and delighted clients — let’s make yours next!
