Solution

We engineered a monetized quiz platform tailored for the Nigerian market, combining gamification mechanics, real-time competitions, and sponsor-led campaigns in one scalable mobile product.

The cross-platform application was developed using Flutter to ensure fast delivery and consistent performance across iOS and Android. Firebase was used for real-time data management, secure user authentication, and quiz content control — enabling the platform to support simultaneous high-load quiz sessions and maintain accurate player tracking.

We integrated Stripe to manage financial transactions, allowing users to securely withdraw their winnings and sponsors to automate payouts. A custom admin panel was built to provide full control over quiz scheduling, content updates, and branding for each campaign — making the platform scalable and fully manageable by the client.

Throughout development, we performed rigorous testing to ensure performance stability, payment security, and seamless quiz experiences. This allowed us to launch a reliable and engaging mobile solution with strong monetization potential and clear value for both users and sponsoring partners
