Web Developer / Front-End Developer with 15+ years of experience building fast, scalable web applications and high-converting landing pages using React and Next.js
I combine engineering-quality frontend with creative motion design crafting interfaces that don’t just work, but feel alive through GSAP + ScrollTrigger, parallax storytelling, micro-interactions, and 3D experiences with Three.js.
As a React Developer / Web Developer, I take full ownership of delivery: I clarify requirements quickly, propose the best technical approach for your goals, communicate clearly, and consistently hit deadlines. I’m comfortable working both from a complete design system and from scratch—when no design is provided, I can create clean, intuitive UI using modern libraries like Material UI, Chakra UI, Ant Design, and Tailwind CSS.
High-performance UI: optimization-focused development (rendering efficiency, lazy loading, code splitting) to keep apps smooth even with heavy animations.
Landing pages that convert: pixel-perfect implementation, responsive layouts, strong content hierarchy, and a solid technical SEO foundation.
Interactive motion design: from subtle micro-interactions to full scroll-driven storytelling and cinematic section transitions.
3D in the browser (Three.js): scenes, materials, lighting, camera work, and interactivity—often combined with GSAP + Three.js for precise, timeline-driven 3D animations (scroll/hover/click).
UI without a design: when design is missing, I can confidently build a professional, consistent interface that feels modern and user-friendly.
🎬 Animation & 3D (my specialty)
I’m passionate about motion-first web experiences: smooth transitions, layered parallax depth, and interactions that guide users through a story.
I use GSAP as my main engine for advanced timelines and ScrollTrigger-based sequences, and Three.js to add depth and “wow” moments interactive hero scenes, product showcases, dynamic 3D backgrounds, and camera-driven effects.
Performance matters: I always consider responsiveness, mobile stability, accessibility (including prefers-reduced-motion), and real-world device constraints.
🧠 Why clients enjoy working with me
Fast, friendly, and reliable communication
Strong ownership and predictable delivery
Business-oriented thinking (solutions, not just code)
