Sigma Dos by Trustsurvey

From Web Surveys to a Dedicated Mobile Experience
Sigma Dos by TrustSurvey is a survey and rewards product where users can discover personalized surveys, earn Sigcoins for their participation, and redeem rewards. The work extended the existing web experience into dedicated iOS and Android applications.
Mobile Product Experience
The mobile app brings survey discovery, reward-based participation, a rewards catalog, and sharing into one cross-platform experience. Notifications help users find available survey opportunities from their phones.
My Role and Implementation
As React Native Developer and Mobile Development Lead, I contributed to translating the existing web product into mobile interactions for iOS and Android. The application used a shared React Native codebase with TypeScript, REST API integration for surveys and rewards, and React Context API for application state.
Outcome
The project gave Sigma Dos users a dedicated mobile way to participate in surveys and engage with the rewards experience across iOS and Android.
