Oleksandr Zaytsev is a Senior Front-end Developer based in Madrid with over a decade of experience building polished, user-focused web interfaces. He has shipped production React applications and modern front-end architectures at companies like Electronic Arts and trivago, and brings deep practical knowledge of ES6, CSS/Sass, webpack/parcel, testing with Jest/Enzyme, and state management with Redux. His career began in full-stack and front-end roles where he combined JavaScript with back-end work (Java, PHP, MySQL), giving him a strong appreciation for end-to-end integration and pragmatic debugging. Comfortable in both startup-style teams and large product organizations, he balances component-level coding discipline with delivery at scale. Outside work he’s a cat lover and keeps a developer’s curiosity alive through hands-on GitHub activity and continuous learning.
