As a React Native Developer at REPL, I contributed to the development of cross-platform mobile applications for enterprise clients, focusing on performance, scalability, and user experience. My responsibilities included building and maintaining modular, reusable components, integrating APIs, debugging complex UI and logic issues, and ensuring consistent functionality across iOS and Android devices. I collaborated closely with designers, backend engineers, and QA teams in an agile environment to deliver high-quality, production-ready features aligned with client requirements. My work also involved improving development workflows, implementing mobile design best practices, and supporting CI/CD pipelines to streamline delivery.
