Iโ€™m a frontend developer with 5+ years of experience building fast, scalable, and polished web applications using JavaScript and TypeScript. Iโ€™ve worked with both creative studios and enterprise SaaS teams, so Iโ€™m comfortable building animation-heavy marketing sites as well as complex, maintainable product systems. ๐Ÿ’ก What I can help you with High-quality UI & animations I create smooth, production-ready animations using GSAP and Pixi.js. Itโ€™s not just about visuals I focus on performance so everything feels fast and responsive. Fast & scalable frontends I build applications in React and Svelte that load quickly, stay maintainable, and scale as your product grows. Frontend architecture Iโ€™ve designed monorepo setups, built shared component libraries, and worked on systems used across multiple teams. End-to-end features If a feature needs backend support, I can handle the Node.js/API side as well. ๐Ÿงฉ Selected work - Auditbull - SaaS audit platform with survey builder, role-based access, and data visualization - Next Level Value - Enterprise CPQ tools and multi-team frontend architecture - Set Snail - Animation-focused marketing sites (Svelte + GSAP + Pixi.js) ๐Ÿ› ๏ธ Tech stack Frontend: React, Svelte, Next.js, TypeScript, Tailwind, GSAP, Pixi.js Backend: Node.js, Express, NestJS, REST APIs Tools: CI/CD, GitHub Actions, SQL ๐Ÿค How I work - I take time to understand the problem before jumping into code - I focus on clean, maintainable, and performant solutions - I communicate clearly and keep things moving - I take ownership from idea to production If youโ€™re looking for someone who can build fast, think critically, and deliver polished results letโ€™s talk.
