This project is a lightweight, high-performance web application designed for garage cooperative management. It is optimized to run on low-power ARMv7 devices (e.g., NanoPI NEO) with strict memory constraints.

This project demonstrates my ability to build modern, efficient C++ solutions for industrial and IoT applications. Following my tenure at Oracle, where I focused on large-scale systems, this project showcases my versatility in:

• Resource-constrained development: Efficient memory and CPU management on 512MB RAM devices.
• Modern C++ Stack: Utilizing C++17, asynchronous networking (Crow/Asio), and SQLite3.
• Full-cycle DevOps: From bare-metal ARM configuration to Nginx reverse-proxy deployment.

• Backend: C++17 (using the Crow Framework for high-concurrency handling).
• Database: SQLite3 with WAL (Write-Ahead Logging) to optimize SD-card lifespan on embedded devices.
• Frontend: HTML5/JavaScript (integrated as a static-file delivery via Nginx).
• Proxy: Nginx as a Reverse Proxy for enhanced security and header management.
• Platform: Ubuntu 24.04.3 LTS on NanoPI NEO (armv7l).

• Admin Authentication: Secure cookie-based role management for administrative tasks.
• Automated Billing Logic: SQL triggers handle complex recurring payment calculations based on dynamic rates.
• Payment History & Debt Tracking: Real-time balance calculations using recursive CTE (Common Table Expressions) in SQLite.
• IoT Ready: Minimalist footprint, designed for 24/7 autonomous operation.

The build process is optimized for low-RAM environments. A temporary swap file is recommended during compilation.
