Software engineer at INSTANVI SARL building PottaPOS, a restaurant system with offline-first sync and sub-second loading for 1000+ products.

Message

At INSTANVI SARL, I build and maintain PottaPOS, a production restaurant management system spanning a WPF desktop app, an ASP.NET Core API, and mobile applications. Its offline-first architecture synchronizes across multiple terminals, and I optimized loading for 1000+ products to under a second.

I also developed PottaAPI, a REST API with 11 endpoints for desktop and mobile clients, including real-time synchronization and validation with FluentValidation. My work includes payment integrations, reporting, inventory management, and contributions to Ntigi Shipment Management, where I implemented barcode scanner integration and receipt and waybill printing.

Across work and personal projects, I've used C#, TypeScript, Python, PHP, and Kotlin to build desktop, web, and mobile applications. I'm currently learning more about Flutter and developing my Python work beyond scripting into FastAPI backends.
