At Viwell, a platform committed to educating, motivating, and empowering individuals to improve their health and well-being, I played a key role in building and scaling the web experience as a Frontend Developer. I led the frontend development of the Viwell Dashboard using React.js, Next.js, TypeScript, and Ant Design, crafting a highly customized and responsive interface that supports real-time analytics, user onboarding, content management (CMS), assessments, events, and rewards modules. This enabled users to seamlessly track their wellness journey and engage more deeply with the platform. To enhance consistency across platforms, I architected a shared JavaScript repository housing core business logic, enabling code reuse between the mobile and web apps while simplifying long-term maintenance. I also introduced dynamic data visualizations using Recharts.js and AntV, providing users with interactive, easy-to-understand insights via visual charts and grids. Working closely with the backend team, I contributed to designing and integrating RESTful and GraphQL APIs, optimizing the data flow between client and server. I also used feature flags to implement new features with gradual rollouts, minimizing risk and ensuring a smooth user experience during deployments. In collaboration with the mobile team, I strengthened my skills in React Native, implemented API integrations, and contributed to developing the mobile rewards module — driving higher user engagement. As part of the migration to Next.js V2, I implemented server-side rendering, achieving a 35% reduction in page load times and significantly boosting overall web performance. To maintain code quality and reliability, I wrote comprehensive unit tests using React Testing Library and Jest, ensuring component stability and robustness across updates.
