  • Conversion of design from Figma to code — pixel perfect layout

    Web Programming
    I convert your design from Figma into clean, working code. Exact pixel-perfect layout that looks the same as in the mockup — in the browser and on all devices.

    What you get:
    — Pixel perfect layout (accuracy to the pixel)
    — Responsive code (mobile, tablets, desktop)
    — Modern clean code in React / Next.js
    — Smooth animations and hover effects
    — Semantic markup (HTML5)
    — SEO-optimized structure
    — Fast page loading
    — Cross-browser compatibility

    What is needed from you:
    Just a link to your Figma file or exported design. If the mockup is missing some states (hover, mobile) — we will agree together.

I want to leave the best and most sincere review about our collaboration.

To be honest, the result turned out even better than I expected. The website looks very cool, everything works exactly as it should, and it is clear that the person really tried to make everything as high quality as possible, rather than just "anyhow, to get it done."

I especially want to thank you for your patience. I think I made about 15 million edits. Here I wanted to adjust something, there I wanted to change something, and then another "little" idea suddenly appeared. And what was very pleasant for me was that there was always a calm reaction to all these edits. You were always in touch, responded quickly, and made changes promptly. This is really very valuable. I also really liked that there was no feeling of "I did it and goodbye." It was clear that it was important to you that the result turned out really great and that I was completely satisfied.

It was easy and comfortable to work: quick communication, a normal attitude towards my endless ideas and edits, attention to detail, and a desire to bring everything to perfection.

Thank you for the work, for your professionalism, and for the nerves that you heroically endured along with my "let's adjust a little more."

I definitely recommend you. If I or my acquaintances need a website again — I will without any doubt turn to you.

Excellent work on the layout of the side menu! Your efforts and attention to detail deserve the highest praise. I especially liked how you managed to create an intuitive and aesthetically appealing menu that is not only functional but also looks great.

Your idea of adding animation when hovering over categories really brought the interface to life. The animation is smooth, unobtrusive, and creates a pleasant user experience. Such details are crucial for the overall impression of the website, and you have executed it perfectly.

I want to specifically mention how you adhered to best practices in modern web development. Using Tailwind CSS for styling and implementing animations is a great choice. It not only simplifies future code maintenance but also ensures high performance.

Thank you for your professionalism and creative approach!
