Hicket - Smart Multi-user Financial Ecosystem

Technical Overview

Hicket is a production-grade financial ecosystem designed for entrepreneurs and organizations requiring sophisticated fiscal control. Built with Expo and React Native, it features a unique 'Transaction State Machine' for deterministic lifecycle management and a multi-tenant architecture powered by Supabase. The application empowers teams through a robust permission system (Owner, Admin, Editor, Viewer), allowing secure collaborative financial management. Real-time data visualization is achieved through a GPU-accelerated OpenGL rendering engine, providing high-performance insights into complex financial patterns.

Problem Statement

Organizations and entrepreneurs lack mobile-first tools that combine individual ease of use with enterprise-level multi-user governance and high-performance financial visualization.

Architecture

Modular dependency injection pattern separating data layers, business logic, and UI. Implements Row Level Security (RLS) and ABAC policies for multi-user data segregation. Uses Expo Router for nested navigation and SecureStore for OAuth 2.0 + PKCE security.

Key Features
