Hi 👋
I’m a Front-End Developer with ⭐ 5 years of experience ⭐, specializing in building modern websites using clean HTML, CSS, and JavaScript.
✔ I help turn Figma / PSD designs into high-quality, responsive websites.
✔ I clone and optimize existing websites, making them clean, well-structured, and fully responsive across all devices.
✔ I deliver turnkey websites — from design and layout to hosting deployment and WordPress integration (with the involvement of my own team).
💡 Here are the key features that make your website stand out from competitors.
🔹 Interactive states for interface elements
According to modern front-end standards, I always implement hover, focus, and active states so the interface feels “alive” and responds clearly to user actions. This is a core requirement in web development. Without interactive states, a website feels static and unfinished.
🔹 Responsive layout (mobile-first or desktop-first)
Your website will display correctly and consistently across all devices — from large screens down to compact smartphones at the iPhone 5 level (~320px).
I also ensure proper adaptation for landscape orientation (when the phone is rotated), which many developers ignore — often making the website inconvenient or unusable in horizontal mode.
For responsiveness, I use up to 4 main breakpoints plus one additional breakpoint for landscape orientation, maintaining control over the layout without unnecessary complexity.
🔹 Retina support and image optimization
I provide higher-resolution images for Retina displays. I use modern formats such as AVIF and WebP, with browser support detection, ensuring images display correctly even in older browsers.
🔹 Component-based (modular) structure
Each interface element is implemented as a separate component. This approach is applied to both SCSS files and HTML. It allows changes to be made in one place, with updates automatically reflected across all pages where the component is used.
This structure makes the website easier to maintain and scale in the future.
🔹 Accessibility
Accessibility improves SEO and allows people who use content-reading software (screen readers) to comfortably navigate and use the website.
🔹 Semantic and valid HTML
Your website will have fully valid HTML, verified according to HTML Validator standards, with proper semantic structure and no unnecessary wrapper elements (div). This is essential for SEO, accessibility, and stable website performance.
🔹 Professional workflow
I use Gulp for build automation, SCSS for efficient styling, and gulp-file-include to manage HTML components.
My main focus is clean, scalable code, fast loading speed, and stable performance across all devices.
If you’re looking for a reliable HTML / CSS / JavaScript developer with strong attention to detail — I’ll be happy to bring your project to life.
