React Developer | Building scalable web apps, UI, API integration & performance optimization
Hi everyone!
I’m a Senior Full-Stack Engineer with 5+ years of commercial experience building scalable, high-performance web applications and modern digital products. My core expertise is JavaScript/TypeScript development, with strong hands-on experience in both frontend (React, Next.js) and backend (Node.js, NestJS). I focus on building clean architecture, reusable components, maintainable APIs, and delivering fast, secure, and production-ready solutions with strong attention to performance and code quality.
I have solid experience translating product requirements and Figma designs into pixel-perfect, responsive, and accessible UI, while also owning features end-to-end - from system design and implementation to testing, deployment, and post-release improvements. I enjoy collaborating closely with product managers, designers, and engineers to deliver solutions that are both technically strong and user-focused
