As a Senior Frontend Engineer at Payoneer, I develop and maintain enterprise-scale fintech applications using React, Next.js, TypeScript, and modern frontend technologies. I have led the migration of key modules to a Micro Frontend architecture using Webpack Module Federation, enabling independent deployments and improving application scalability. I work closely with engineering teams across multiple regions to deliver new features, review technical designs, and maintain high development standards. My responsibilities also include improving application performance, optimizing Core Web Vitals, writing reusable UI components, integrating backend APIs, and ensuring code quality through Cypress and Playwright end-to-end testing. I focus on building maintainable, production-ready applications that are easy to extend and scale.
