Show HN: HCB Mobile – financial app built by 17 y/o, processing $6M/month (hackclub.com)

Mohamad, a 17-year-old from the San Francisco Bay Area, has successfully launched the HCB Mobile app, which service over 6,500 teenager-led nonprofits, clubs, and hackathons. HCB provides essential financial services, including nonprofit status, banking, and donation platforms, processing an impressive $6 million monthly. The mobile app, developed to enhance financial management for these youth-led organizations, is significant as it empowers teenagers to more effectively manage their projects and engage with their communities. The app is built using Expo, a React Native framework, enabling cross-platform functionality without the burden of maintaining separate codebases for iOS and Android. Mohamad learned to create his own Expo Modules to integrate native features and enhance app performance through techniques like memoization. Moreover, he navigated complex approval processes with Apple and Google to secure permissions for advanced features like mobile payment processing with Stripe. After dedicating over 250 hours to development, HCB Mobile stands as a testament to youth innovation in fintech, promoting the seamless operation of nonprofits driven by the younger generation.
