Worked on the FellouAI/eko repository to enhance local browser data management and navigation by developing new features within the LocalCookiesBrowserAgent. Focused on implementing robust localStorage handling and introducing an openUrl method, enabling more reliable navigation to specified URLs. Improved cookie expiration logic and updated package dependencies to strengthen maintainability and security. Leveraged TypeScript and Node.js to refine data retrieval and storage paths, ensuring greater session stability and reliability for client-side browser automation. The work demonstrated a strong grasp of browser storage APIs and full stack development, contributing to more resilient offline and online user flows within the application.
