I’ve just completed Invoice Manager — a production-ready Windows desktop application built with .NET 10, C#, WPF, MVVM, EF Core and SQLite.
The application covers the full workflow from quotation to payment, including:
• customer and service management
• quotations and invoices
• quote-to-invoice conversion
• partial and full payments
• PDF generation
• dashboard reporting
• historical document snapshots
• automated testing and CI
The project was built with Clean Architecture and includes 97 automated tests, a self-contained Windows release, technical documentation and architecture decisions.
This project gave me a chance to work not only on the UI, but also on business rules, persistence, transactional workflows, testing and release engineering.

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.
