How I Built a Zero-Knowledge Finance App Without the Cloud
Building a modern mobile application usually means relying on the cloud. You hook up a BaaS, send user data to an API, process it through an LLM or a Python backend, and send the results back.
But what happens when you build a personal finance app and absolutely refuse to send a single byte of plaintext data over the internet?
When I started architecting my solo project, KashIQ, I locked myself into a brutal constraint: 100% Offline-First, Zero-Knowledge Architecture (ZKA). No API calls for processing. No plaintext databases.
This created a massive engineering paradox. How do you deliver predictive behavioral analysis, machine learning, and seamless multi-device synchronization without cloud servers, and without freezing the Flutter UI thread?
Here is the architectural deep-dive into how I bypassed the cloud by embedding aerospace algorithms natively via C++ FFI, securing SQLite at the disk level, and building a peer-to-peer optical bridge...
