🚀 Take a look at our newly upgraded Enterprise POS architecture in action! We completely re-engineered this system, migrating from a Python CustomTkinter GUI to a lightning-fast Tauri front-end paired with a robust Python FastAPI backend.

🔄 The Architecture Upgrade: CustomTkinter to Tauri

Modern Web UI: We stripped away the rigid CustomTkinter framework and rebuilt the front-end using standard HTML, CSS, and vanilla JavaScript. This shift allows for pixel-perfect styling, fluid animations, and a much cleaner, responsive layout.

Decoupled FastAPI Backend: Instead of weaving the UI and database logic together, Python now acts as a standalone, high-performance API. The FastAPI backend handles all the heavy SQLite database operations, keeping the application incredibly snappy.

Seamless API Communication: The front-end and back-end now communicate flawlessly via local HTTP endpoints, allowing the UI to fetch live inventory and process checkouts asynchronously.

The Tauri Magic: Tauri wraps this entire modern web stack into a highly optimized, low-memory native desktop executable, automatically spawning the Python backend as a silent background sidecar process.

🛒 Live Sales Terminal: Watch how seamlessly the checkout flow operates. Users can quickly select products from a searchable catalog, append them to the live billing ledger, and instantly complete transactions with zero lag.

📦 Master Inventory Manager: Total control over stock is just a few clicks away. We showcase the live adjustment capabilities by selecting an item in the manual correction terminal, inputting an intervention magnitude of 55 units, and securely updating the database through a clean confirmation modal.

📊 Deep Analytics & Logs: Data drives decisions. The walkthrough highlights the comprehensive transaction ledger tracking real-time daily metrics—like total revenue, transaction counts, and top-selling products—alongside a detailed, modal-based Monthly Sales Summary.

⚡ This project proves that robust, localized SQLite databases and powerful Python backends can be perfectly paired with beautifully sleek, modern web-based user interfaces.

Relivo — Multi-Store Retail POS & Inventory Orchestration Platform 🛍️✨ 

Relivo is an enterprise-grade retail management web app built around real-time inventory observability, order auditability, and seamless customer retention. 

The goal was to remove register checkout friction and multi-branch inventory opacity — pairing high-contrast OLED dark panels with vibrant status badges and structured tabular grids to make high-volume store tracking feel effortless. 

Special attention was given to:

• A product-focused catalog grid managing 1,482 SKUs with real-time stock threshold bars, margin calculations, and channel tags.

• Full-spectrum order audit feeds tracking turn-level transaction events from item addition down to receipt printing and pickup confirmation.

• Customer CRM integration connecting loyalty points (Gold Tier) and purchase histories directly to active order inspection panels.

• Granular transaction tracking separating payments across Visa, QRIS, GoPay, and Cash alongside exception statuses (Part. refunded, Refunded).

• High-visibility neon status badges (Out of stock, Low stock, Processing, Completed) for instant scannability during busy shifts.

• An elevated presentation aesthetic showcasing dark tablet and desktop displays resting on textured metallic and ambient backlit surfaces.

The result is a fast, reliable digital workspace that combines raw enterprise utility with modern software sophistication.
