Why I Built This

I wanted to make everyday expense tracking feel simple enough to use consistently while still giving people useful insight into their spending. Vaultly turns scattered transactions into a secure, real-time experience that works across a modern mobile workflow and can grow with the user's financial habits.

Key Decisions & Challenges

  • Chose Flutter to build a consistent mobile experience from one maintainable codebase.
  • Used Supabase for authentication, PostgreSQL data, storage, and real-time sync so financial data stays connected and structured.
  • Added Firebase services and GitHub Actions to support notifications, quality checks, and repeatable Play Store delivery.
