About
I'm a Frontend Developer with over 8 years of experience creating fast, beautiful, and interactive websites and web apps.
I specialize in fully responsive websites using Next.js, TypeScript, Animations, Data Visualization, Gamification, Games, Photo Editors and more.
I help clients boost revenue and user engagement by building fast web applications with seamless, engaging UX that keeps visitors coming back.
My core stack includes Next.js(React), Vercel/Netlify/Supabase, TypeScript, Bootstrap/Material UI/TailwindCSS, GSAP/Lax.JS/Lottie, Canvas, Phaser.js, and tools like Git, Figma and many other.
I love music and in my spare time I play guitar. Besides web development, I’m building a music bot for Telegram.
I post (used to post) on X (formerly Twitter) and make some fun things on CodePen.
