About
MobiDev developed a cross-platform fintech app for a US startup to improve financial literacy and simplify family budget planning. Built with Flutter, the app enables users to create complex automated rules for saving and spending while maintaining individual privacy. By integrating Plaid, the platform connects to thousands of banks. It features a hierarchical permission system, allowing parents to guide children’s financial habits through shared
Challenge, approach, and impact
Simplifying Complex Automation
MobiDev addressed the $400B financial illiteracy crisis by creating a family fintech app with an intuitive "rules engine." The challenge was automating complex transfers (e.g., saving 30% of surplus salary) via a secure, event-driven architecture. The scope required managing a family account network where parents track children’s spending while keeping their own personal financial data private through hierarchical permissions.

“What I find most impressive about the Family Finance project is how we took a high-level mathematical problem—complex transaction rules—and turned it into something a teenager could easily use. We didn't just build another banking app; we built a financial education tool. The decision to use an event-driven architecture was key; it allows the 'rules' to fire instantly without lag, making the automation feel like magic to the user. Integrating Plaid was a massive undertaking for a startup budget, but it gave the app immediate credibility and reach. It’s a great example of using a modern tech stack like Flutter to deliver an enterprise-grade fintech experience at startup speed.“
