About

Hi, I’m Nataliia Petrychuk, a front-end developer with hands-on experience in React.js, Next.js, and responsive web applications. I enjoy turning design concepts into accessible, pixel-perfect interfaces and collaborating with designers, developers, and stakeholders in Agile environments to deliver value for government and enterprise clients.

I thrive on building reliable, scalable UI solutions, optimizing performance and accessibility, and embracing AI-assisted tools to accelerate prototyping and delivery. I’m always keen to learn new technologies and contribute to diverse teams to create meaningful user experiences.
